1.1

About the complete set of manuals for an IED The user’s manual (UM) is a complete set of five different manuals:

Application manual

Technical reference manual

Installation and commissioning manual

Operator´s manual

Engineering guide

en06000097.vsd

The Application Manual (AM) contains application descriptions, setting guidelines and setting parameters sorted per function. The application manual should be used to find out when and for what purpose a typical protection function could be used. The manual should also be used when calculating settings. The Technical Reference Manual (TRM) contains application and functionality descriptions and it lists function blocks, logic diagrams, input and output signals, setting parameters and technical data sorted per function. The technical reference manual should be used as a technical reference during the engineering phase, installation and commissioning phase, and during normal service. The Installation and Commissioning Manual (ICM) contains instructions on how to install and commission the protection IED. The manual can also be used as a reference during periodic testing. The manual covers procedures for mechanical and electrical installation, energizing and checking of external circuitry, setting and configuration as well as verifying settings and performing directional tests. The chapters are organized in the chronological order (indicated by chapter/section numbers) in which the protection IED should be installed and commissioned. The Operator’s Manual (OM) contains instructions on how to operate the protection IED during normal service once it has been commissioned. The operator’s manual can be used to find out how to handle disturbances or how to view calculated and measured network data in order to determine the cause of a fault. The IED 670 Engineering guide (EG) contains instructions on how to engineer the IED 670 products. The manual guides to use the different tool components for IED 670 engineering. It also guides how to handle the tool component available to read disturbance files from the IEDs on the basis of the IEC 61850 definitions. The third part is an introduction about the diagnostic tool components available for IED 670 products and the PCM 600 tool.

Chapter 2 IEC 61850 station engineering

Station engineering in IEC 61850 The way of engineering and configuring a station according to IEC 61850 standard is described in part 6 of the standard. The title of this part is: “Configuration description language for communication in electrical substations related to IEDs” This chapter contains some explanations about the definitions made by the standard. They may be requested to get a better understanding and as a reference when the different engineering steps made with the tools PCM 600/CCT are described. It is expected, recommended that the reader has a general knowledge about the IEC 61850 standard and especially of the parts 6 and 7.

Station engineering in IEC 61850

Chapter 2 IEC 61850 station engineering

The standard defines two tools and four file types for station engineering. The above figure shows these tools and files in their relation. In the ideal situation from top down the engineering process and the used tools and files have the following relation: •







System Configurator tool (SC) - Import a station.SSD file when available. If not continue with the next step - Import the ied.ICD files of the products which will be used - When no station.SSD file is available, configure the primary equipment (Busbar, Transformer, Apparatus, connections etc. to voltage level and bays. Make a single line diagram of the station. Remark: This step and the next one is not direct needed to do signal engineering in a station for IEC 61850 based communication. A minimum configuration of the plant structure is requested only. - Place the Logical nodes to the primary equipment they belong to within a bay. - Configure the communication with their subnetworks. - Place the physical IEDs in the communication subnetwork and define the access points per IED - Place the IEDs with their Logical devices and Logical nodes in the plant structure - Do signal engineering. Configure DataSets, Control Blocks and link the communication path between server and clients or between servers (GOOSE). - Export the complete station configuration in the station.SSD file for further use by the various IED Configurator tools IED Configurator tool (IC) - Import the station.SCD file and extract the information valid and used for each used IED. - Do additional engineering steps when necessary (vendor specific) - Check for received GOOSE messages and do GOOSE signal marshalling when necessary - Prepare the ied.CID file and download the file to the IED - Precondition in this case: The IED is fully engineered to its function in the project. The ied.ICD file was exported with the complete configuration to the SC tool as described above. SSD file = System Specification Description file - This file describes the single line diagram of the substation and the required Logical nodes. It is expected that the utility is able to support the project with such a file. ICD file = IED Capability Description file - This file describes the full capability in Logical nodes and Logical devices of an IED without any relation to the substation and communication organization. This is the basis for the SC tool about the volume and capability of the selected IED for signal engineering. This file is possible in two principle variants. First it is a general description without a direct project specific configuration and programming. This file describes the general capability. Second it is the ied.ICD file of the full engineered IED according to project

Chapter 2 IEC 61850 station engineering

specification and requirements. In this case the volume of available Logical nodes and therefore signals will be the final one. Which variant is used must be clarified within the project. SCD file = Station Configuration Description file - An SCD file is given when the substation and communication section contains configured values. This file contains all IEDs, a communication configuration section and a substation section. CID file = Configured IED Description file - The CID file contents is not part of the standard. It is vendor specific. It should contain the result of the engineering process on IED and station level. As it can be seen there are various possibilities in which order the engineering will be done. Especially the bay level IED for protection and control may need in most cases project specific adaptations and configuration, which has influence on the volume of used Logical nodes and therefore data objects. The concept allows to re-import an extended ied.ICD file and to add or delete signals in the station. The tools have to support this concept.

Chapter 2 IEC 61850 station engineering

Designation model of IEC 61850 The description in the following sections will reference to an example station. This is relevant for the description of the object designation and signal addressing requirements. A substation of any size consists of buildings, a lot of primary equipment, substation control equipment and a lot more. Each item has a name and will be identified by explaining to which part it belongs to. The rules will differ from country to country and by each utility.

Designation model of IEC 61850

Chapter 2 IEC 61850 station engineering

The IEC 61850 standard is based on the hierarchical addressing and designation model in a station. It follows in this way the structure of the substation equipment independent of IED structure and organization. This designation and addressing model is also visible in the IEC 61850 telegrams because the address is presented in MMS as an ASCII string, so the address can be seen directly in a readable form. The above figure shows a virtual example station. The identification is based on the IEC 61346 concepts. Reasons to use the IEC 61346 model: • • • • •

the IEC 61346 has the task to define structuring principles and reference designations. the standard is international in the same way as IEC 61850 is the standard has made a concept which can be used in all industrial systems independent of a language, project etc. the standard use only single characters per level which makes the total designation very short and therefore saves bytes to be transmitted. by using this designation model in IEC 61850 it allows to use an easy project independent identification.

The designation of a Logical node and its signals (DO) is needed to identify it to the primary object etc. The hierarchical order in a substation is the path to identify the LN.

The designation path to get the position of the circuit breaker as an example would be: • •

DeStat => E1 => Q1 => LD1 => QA1 => XCBR1 => Pos => stVal in IEC 61850 = DeStat.E1Q1/LD1QA1XCBR1.Pos.stVal

and for the operate signal of the time overcurrent protection: • •

DeStat => E1 => Q1 => LD2 => P => PTOC => Op in IEC 61850 = DeStat.E1Q1/LD2P.PTOC.Op

Designation model of IEC 61850

Chapter 2 IEC 61850 station engineering

The above model of designation identification is possible when the station configuration is based on the “FuncName” method in IED 61850. This is specified in the Header section of the SCL file. The standard identifies these object or signal designations as the technical key. The standard recommends to use the IEC 61346 based designation model, but it is not a must. But a similar naming structure is requested when an existing identification concept has to be used.

2.1

IEC 61346 designation model used for IEC 61850 Basics of the IEC 61346 standard: •







three different views are defined - the functional view (identified by =) - the product view (identified by -) - the location view (identified by +) to separate two levels in a row the character “.” is used. It is allowed to leave the “.” out, when the last character is a digit and the first character of the next level is a letter. the transition from one view to another is visible when both identification signs are used in the sequence from > to. E.g. =-QA1 indicates this is a transition from functional view “=” to product view “-”. The functional view is here the bay Q1 and the product is the circuit breaker QA1. each level is represented by one character. A second character is used to identify a type within a level, e.g. QB = HV switching equipment of type disconnector, QA = circuit breaker and QC = grounding disconnectors.

The IEC 61346 defines the rules etc. and gives explanations how to organize the structure and the use of the characters but it does not give a model for each industrial area. This has to be done by working groups. For the substations for electrical energy distribution the German community of interest “IG EVU” has taken this task. Member of the IG EVU are beside others the main vendors and the main utilities of Germany. The papers are available and free of charge via Internet “www.igevu.de”. The documents can be found on the page “Veröffentlichungen”. The following extracts of the designation trees shows the position of the used elements.

Substation Configuration description Language (SCL)

3

Chapter 2 IEC 61850 station engineering

Substation Configuration description Language (SCL) The SCL language is based on XML. It is of course not needed to know the XML file in its details and do any step which requests XML knowledge, but the organization of the information within the SCL files (ied.ICD and/or station.SCD) might be of interest. Especially to know where the engineering additions like DataSets and Control Blocks belongs to. The SCL XML file is defined in five sections or descriptions, which are specified in IEC 61850–6 clause 9. These sections are: • • • • •

the Header the Substation description (section) the Communication description (section) the IED description (section) the Data Type Templates

The first two sections can be seen as tasks to organize the IEDs within the substation and to establish the communication. These tasks are done by the PCM 600 tool. The Logical nodes as part of the IED are logically linked to the substation section by PCM 600. The signal engineering task and routing of the signals is the task of the CCT tool. Its precondition is that PCM 600 has done the complete organization on the two sections substation and communication. The DataSets and Control Blocks configured by the CCT tool are located in the IED section because they are logically defined as part of the Logical nodes (see IEC 61850–7–2 clause 9). The CCT needs the correct configured communication section when it comes to GOOSE engineering. The Data type templates section is requested to give the correct content description of each Logical node type to all user of the information. These are the clients. Each IED and vendor may have/has its own Logical node type definitions.

A reference to the GoCB is included in the communication section when the GoCB is configured. The above graphical presentation of the XML file is a standard view of XML editors. It gives a better picture about the structure of the XML contents.

3.1

The Substation section The substation description in IEC 61850–6 clause 9 describes the organization of the primary equipment in a single line diagram on one side. On the other side it describes the used LNs belonging to a bay. The second part is of interest for the signal engineering. In part 6 clause 8.4 of the standard the object and signal designation rules are described. The identification for the signals are therefore also used in the telegrams defined in IEC 61850–8–1 is named “Technical key”. The technical key is used within the SCL description to identify and reference objects. See chapter 2, section 1 "Station engineering in IEC 61850" about the concept based on IEC 61346. PCM 600 generates an “SCL Technical key” independent of the naming given by the project. The PCM 600 generated technical key is based on the definitions given in IEC 61346 and for electrical substations. When a project is using its own naming model this will be used by the SCL description as technical key. PCM 600 allows to select the version which should be used in the SCL files when exporting a station.SCD file.

Signal identification in the communication system The signal identification rules used by IEC 61850 are described in part 7–2 clause 19.2. and used in part 6 clause 8.4.2 The signal designation consists of four parts: 1. a user defined part identifying the Logical device LD in the process (LDName) 2. a function related part to distinguish several LNs of the same class within the same LD/IED (LN-Prefix) 3. the standardized LN class name and the LN instance number, which distinguishes several LNs of the same class and prefix within the same LD/IED 4. a signal identification inside a LN consisting of data and attribute name as defined in IEC 61850–7–3 and IEC 61850–7–4

The above figure is taken from the standard IEC 61850–6 (figure 5). The standard defines two options how to use part 1 and part 2 above: 1. Function related naming • identified in the SCL header with NameStructure = FuncName 2. Product related naming • identified in the SCL header with NameStructure = IEDName Within one SCL project only one option can be used.

19

Substation Configuration description Language (SCL)

Chapter 2 IEC 61850 station engineering

The LDName part is build in this option out of the objects IED (A) and LD (B). The link to the primary process is not given in this model. The LNName is in this option the LN Prefix, the LN class and the LN instance no (C). The LN prefix allows in this model to identify several versions of a LN class. For example the eight different versions the LN class PDIF. The link between the IED and the primary process (Substation (1), Voltage level (2), bay (3)) is given in the substation section of the station.SCD file but not in the signal identification in the telegram. The project may decide how to deal with this matter. The IED name may be extended with a short form of the three missing levels. The IEDName must be unique in this designation model. Remark: The standard defines the maximum length for the signal naming and for identification parts to 32 ASCII characters each. This has to be regarded for the object identification for part 1 to part 4 (see figure 6). In addition it might be possible that client IEDs have additional restrictions which have to be taken into account. Most vendor have to use the LN Prefix to identify their versions etc. Therefore the product related naming model (IEDName) will be used.

3.2

The communication section The organization of the physical IEDs to the communication network is independent of the substation structure. The IEC 61850 standard defines the communication network with no relation to an existing media and protocol. The first mapping to an existing media and protocol is done in IEC 61850–8–1 with: • •

Ethernet as medium MMS (Manufacturing Message Specification) protocol as defined in ISO 9506–1 and IOS 9506–2.

The IEC 61850 standard describes in part 7–2 the Abstract Communication Service Interface (ACSI) in a media and protocol independent form. Part 8–1 specifies the mapping of this ACSI to the existing MMS. The communication section in the SCL file describes the minimum of what is needed to identify how information is routed between the IEDs in a project. This is. • • • • • •

The link to the IEDs is done by PCM 600 when the IED is placed and the link to the subnetwork established. The list of “Connected AP” in the communication section of the SCL file includes all IEDs with their APName. A station as shown in figure 3 the station uses two voltage levels with a set of bays and IEDs per bay. The communication network can be done in several ways for this station. The most typical variants are shown in figure 10.

Both variants fulfil the requirements and performance. Variant 2 may be used, when the availability question is discussed. In this case only one voltage level of the station is lost when a subnetwork fails. The client IEDs must be able to handle two access points.

The IED section The IED section describes the complete IED as it is needed for IEC 61850 communication and signal engineering. The Data Type Template part of an IED may be seen as part of the IED, even when separated in its own section. The ied.ICD files includes the description of the LNs, their Data Type Templates and the used/supported services. The structure of the IED section follows the definitions made in the IEC 61850 standard. There are two basic IED types which are used: •

22

station level IEDs - IEDs located on station level and dealing with the information transmitted from/to the bay IEDs are identified as client IEDs. They are represented by Logical nodes of group “Information (I)”. This are the LNs = ITCI, IHMI and

Chapter 2 IEC 61850 station engineering

Substation Configuration description Language (SCL)



ITMI. They are the receiver of information in monitoring direction and sender of commands (control). These LNs have no data objects. They are only used to do the link of the report control blocks (BRCBs) from the server IEDs. bay level IEDs - all IEDs on bay level are server IEDs.

Signal engineering is done within the server IEDs.

Organization of LDs, LNs, DOs and DAs in an IED

The above figure is a short summary about the logical organization of the signals below the IED. • • •

A server represents the communication interface to the subnetwork (Ethernet). one or more Logical device(s) are connected to a server a set of Logical nodes belong to a LD

23

Substation Configuration description Language (SCL)

• • • •

Chapter 2 IEC 61850 station engineering

the LN LLN0 is a special LN per LD and contains the DataSets, the various control blocks, inputs (from GOOSE messages) etc. The LN LPHD is a special LN per LD and contains data objects which describe the status of the physical device (the IED) each Logical node represents a function and contains a number of data objects (DO) each DO is represented by a number of data attributes (DA)

The data objects are representing information signals which may be routed to station level IEDs. So the signal engineering task is to select the requested signals (DOs) and link them to the client IEDs as receiver. The control services are not directly engineered. They are included in the data objects which handle both directions the command (control) and the response (monitoring). So when routing the DO in monitoring direction the control is then also known by the clients. The organization of the IED from LD down to DAs can be viewed in the CCT tool. This organization concept has to be taken into consideration when DataSets are configured. The number of data objects and data attributes per DO is defined by the used LN type in this IED. The contents is taken from the Data Type Templates which belong to an IED type.

3.4

Signal engineering DataSets IEC 61850 has defined DataSets and report control blocks for signal transmission in monitoring direction. DataSets are also used for GOOSE messages in horizontal direction. Which data objects or single data attributes should be collected in a DataSet is not specified and can be done to rules which may be defined in a project. The following figure shows a DataSet where all position information of the apparatuses of a bay are put into one DataSet. The vendor of an IED can define DataSets as defaults which are part of the IED and always available. They need to be linked to the client IEDs only when you want to use them as they are. The vendor has to declare when these DataSets can be modified to projects need or not.

IEC 61850–7–2: Example of a DataSet

General rules for DataSet configuration: • • • •

All data objects or their data attributes which are signals in monitoring direction can be selected for a DataSet only those data attributes of a data object can/will be selected which have the same function constraint (FC). data objects with different FC can be selected for a DataSet. For example DOs with FC = ST and DOs with FC=MX can be member in one DataSet. a single data attribute can be selected when it is specified with a trigger option. For example the data attribute stVal of the data object Pos can be selected as a member of a DataSet, because it is specified with the trigger option data change detected (dchg).

The description of the DataSets with name and the list of data object members (FCDAs = Functional Constraint Data Attributes) is included in the SCL file in the IED section in the Logical device subsection. As specified in IEC 61850–7–2 clause 9, the DataSets are part of a Logical node. They are most likely included in the LLN0.

3.4.1

Buffered Report Control Block (BRCB) To be able to transmit the signals configured in a DataSet a BRCB must be configured which handles and specifies how the events will be transmitted to the clients.

25

Substation Configuration description Language (SCL)

Chapter 2 IEC 61850 station engineering

The contents of a BRCB is listed in IEC 61850– 7–2 in clause 14, table 23. The BRCB contains a lot of attributes which are of interest to handle and secure the communication between the client and the server and may be set once as default in a project. Others are of application interest in the way events are handled in a project. •









Buffer time - This parameter describes how long the report should wait for other expected events before it will send the report to the client. When it is known, that additional events will be generated as a follow up it is useful to wait for example 500 ms for additional events stored in the report. This feature reduces the number of telegrams transmitted in case of a burst of changes. But on the other side it increases the overall transaction time for events from IED input to presentation on HSI which is normally defined to be one second! Trigger options - The data attributes know three different trigger options (dchg, qchg, dupd). Within the BRCB the two other can be defined (integrity and general interrogation). The attribute Trigger option is a multiple choice and allows to mask the supported trigger options in this BRCB. Integrity period - When integrity is selected in the trigger option attribute, it is needed to define an integrity period to force the transmission of all data listed in the DataSet. This is done by the attribute Integrity period. This feature can be used as a background cycle to ensure that the process image in all partners is the same. Nobody is perfect and someone in the long chain from the contact up to the NCC may have lost an event. The background cycle can repair it. General interrogation - A general interrogation is only done on request from a client. Not all Data-sets may contain information which is needed for a general update of the client. For example data with T(ransient) = TRUE are not part of a GI. When the BRCB attribute general interrogation is set to TRUE a GI request from the client will be handled. The report handler will transmit all data defined in the Data-set with their actual values. The IEC 61850 standard defines that all buffered events shall be transmitted first before the GI is started. A running GI shall be stopped and a new GI shall be started, when a new GI request is received while a GI is running. Purge buffer - This BRCB attribute can be used by a client to clean the event buffer from old events. The events are discarded on request of the client. This feature can be used to delete old events not transmitted to the client due to stopped communication. After the link is reestablished the client can decide to clean the buffer or to receive the history.

Trigger Options IEC 61850 has defined in total five different TrgOp. Three of them belonging to data attributes and marked per data attribute in the column TrgOp of the CDC tables in part 7–3. The other two belonging to the configuration of control blocks. The five trigger options are: •

26

dchg = data-change

Substation Configuration description Language (SCL)

Chapter 2 IEC 61850 station engineering

-









The classical trigger. Whenever a process value has changed its value either binary or a measurement a transmission is done. How it is detected and how the Logical node is informed is not part of the standard. qchg = quality change - Looking to the possibilities of the quality data attribute type (q) any changes in the quality description will be transmitted. dupd = data value update - This trigger option give the possibility to define that a transmission should be done on a condition which can be controlled by the application. integrity - This trigger will force the transmission of all process values defined in the Data-set when a timer value (the integrity period) expires. It can be used for example to do a process signal update in the background (e.g. every 15 minutes). general interrogation - This trigger is forced by the clients (= station level IED; NCC gateway, station HMI, ...). Normally a GI is asked for, when the client and the server start or restart a session. When the client is able to receive the actual values and when the Logical device has scanned all process values at least once, an image of the actual process signal status can be transmitted to the client.

Link BRCB to a client LN The BRCB has to know to whom the events shall be transmitted. This is the signal routing engineering step. The IEC standard 61850–6 describes that this is given by including the LN of the client IED in the ReportBlockEnabled option. The selected client IED with the corresponding LN (e.g. ITCI) is included in the SCL structure of the Report Control description of the IED section. CCT is doing it when the client LN is linked with the name field of the BRCB by the drag-and-drop method. The description of the BRCB with selected DataSet, configured parameters and selected IEDs is included in the SCL file in the IED section in the LN0 structure for the LD where this LN0 belongs to.

IEC 61850: Principle operation of GOOSE messages

The Generic Object Oriented Substation Event (GOOSE) class model is used to distribute input and output data values between IEDs on bay level (in horizontal direction) through the use of multicast services. GOOSE messages bypass the server and enables a fast transmission from publisher to one or several subscribers (receivers).

29

Substation Configuration description Language (SCL)

Chapter 2 IEC 61850 station engineering

GOOSE messages are unidirectional, send only messages which request an application specific method to secure that sender and receiver of the message operates safely. This implies that the receiver of the GOOSE message distributes also GOOSE messages and close the loop for communication (request — respond on application level). The return message is not a must. It depends on the application in which way a confirmation may be done. The GOOSE message concept will be used for all application functions where two or more IEDs are involved. Typical example is the station-wide interlocking procedure. The very simplified figure above shows the GOOSE concept for three IEDs which interchange GOOSE messages between each other. To send GOOSE messages a GoCB must be defined and a DataSet is needed which contains the data objects of single data attributes to be send. A GOOSE message is forced to be transmitted when a trigger change is detected for a data attribute. All members of the Data-set will be copied in the send buffer with their actual value and the message is sent. All subscriber which knows the address of this GOOSE message will receive the telegram. The GOOSE message includes sequence number etc. to verify that all messages are received. The concept what has to be done in case of a lost message etc. is part of the application and not described in the standard. The DataSet for GOOSE messages are configured in the way described above. A GoCB has to be defined per GOOSE-DataSet. GOOSE messages bypass the server and send direct from the communication part on the Ethernet. This is identified for the communication in the SCL communication section in the GSE element, where the name of the GoCB is listed under the ConnectedAP.

Link GoCB to an IED The IEDs which should receive this GOOSE message must be known and they have to be informed in the engineering state that they will receive GOOSE messages. This is given when the external Reference, the name of the IED and the member of the DataSet is included in the LN0 under the structure of the LD of the receiving IED. This part is identified as “Inputs”. The IEDs which shall receive the GOOSE are selected by CCT. CCT is doing it when the IED itself (the IED icon) is linked with the name field of the GoCB by the drag-and-drop method.

Chapter 3 IEC 61850 Station configuration tasks

IEC 61850 Station configuration tasks The IEC 61850 standard defines the complete part needed for information communication in a substation. This can be split into the following parts: • • • • •

the definition of data objects and their common data classes with their data attributes the definition of Logical nodes (LN) as the communication interface for a substation function (e.g. a protection function) the definition of a basic communication structure for substation and feeder equipment the practical mapping of the communication to an existing protocol the MMS the definition of the engineering process for a substation control system in a configuration description language for communication in electrical substations

We refer to the IEC 61850 standards in their actual version as a basis for the engineering tasks described inhere by using the PCM 600 and the CCT. The main parts which are of interest are described in a brief form in chapter 2 "IEC 61850 station engineering". A short form of the complete station and signal engineering sequence can be described as shown in the following figure.

Chapter 4 PCM 600 and CCT tool set for station engineering

PCM 600 and CCT tool set for station engineering PCM 600 and CCT are state of the art tool sets based on Microsoft.net technology. The two tools are able to do the station configuration tasks as defined by IEC 61850–6. They are doing it for the IED and subnetwork configuration in a plant structure and in a communication structure by PCM 600. The signal engineering which is defined by the DataSets, the report control blocks and the GOOSE messages is done with the CCT. PCM 600 is a tool which supports in itself the tasks needed to do IEC 61850 station engineering but it is also the platform for several sets of tool components used to support IED engineering for ABB IED product families. This manual describes the IEC 61850 station configuration task only. It is requested to use the IED engineering guide manuals in addition when ABB IEDs are part of the IEC 61850 based station project. The description of the PCM 600 is limited in most cases to the part needed for IEC 61850 station configuration. The CCT is a tool which is used by ABB as a base product for signal engineering of several protocols. This version of CCT is also limited to the tasks needed to do signal engineering for IEC 61850 protocol. The precondition to use CCT is that the plant structure with the IEDs and the communication structure is build by PCM 600. See chapter 3 "IEC 61850 Station configuration tasks" for a description of the general tasks for IEC 61850 station configuration by using PCM 600 and CCT.

PCM 600 views and windows The PCM 600 tool set runs under the operating system Windows 2000 or Windows XP. It is expected that the user is familiar with the handling and use of the Windows platform. In this chapter only those items are explained and shown which are specific to PCM 600 but still based on Microsoft windows methods. When you start PCM 600 and no project is already selected you will get an empty window with the base menubar and toolbar only. Once you have selected a project, you will be given the possibility to select different views. The start menu of a project may look like the menu shown in the figure below.

the plant structure the communication structure

The plant structure is the most commonly used view and shows the organization of the stations in the geographical order top down from a defined highest level (e.g. the network control center (NCC)) down to each IED logically connected to a bay in the station. The plant structure is used to select the tools per IED. The communication structure is not needed for normal operation. It is used to view the communication network and links from the PCM 600 to each IED. Only the private communication from the PCM 600 to each IED is managed and handled by the PCM 600. To select the communication structure do a right mouse click on the area next to the Plant Structure tab. Select communication and an additional page will be included which shows the communication structure of the PCM 600

Object Properties The Object Properties window is a standard Microsoft window which allows the user to view and when needed to modify properties of the selected object. In the PCM 600 frame this window is used by some tools like GDE to insert the IP address of the IED selected and some other properties like object naming in the HMI picture and so on. It might be necessary to check some properties for communication to adapt and synchronize the communication network. The shown properties in the object properties window follow the selected object in the Project Explorer or in a tool.

Output The Output window is shown on the bottom array of the PCM 600 screen when selected. It is a log script which is used by PCM 600 to list all activities, warnings, error messages etc. which come up during operation of the PCM 600. It might be needed and used when a task does not operate as expected. The information in the output list may provide a clue as to why it does not operate etc. The Output view is not needed for normal operation and can be closed.

IED tools These tools are not used for IEC 61850 station configuration. Each started IED tool will be visible in the residual screen area surrounded by the three windows Plant Structure, Object Properties and Output. For normal operation only the Plant Structure is needed and it is recommended to close the other two windows. More then one tool can be open at the same time for one IED or for some IEDs in parallel. But only one tool at a time is active. The tool is selected either by its tool tab or by selecting the IED. See the IED engineering guide manuals for more derails.

The window keeps open after your selection. Depending on the selected object it will show directly the possible choices.

Save tool engineering results PCM 600 stores additions and changes in the plant and communication structure direct in its database. This function is not needed for IEC 61850 station configuration. The PCM 600 stores all changes for which it is responsible directly in the database. This is useful because these changes are only of type organization and have no influence on IED data. Changes, additions etc. done within a tool are only moved to the project database when they are saved. This possibility is context sensitive and will be displayed in the PCM 600 base menu bar under File when a tool has the ability to save.

PCM 600 options for operation The options can be selected from the menulist Tools>Options. A pop up window will be displayed showing the entry point for the four different options. The four option windows are: 1. Log Configuration • to organize the log file which is produced during the sessions and shown in the Output view of PCM 600 2. Category Manager • allows the definition of user groups with different rights to work with PCM 600 according to their need and task. 3. System Settings • specifies the basic decision about access rights for PCM 600 by the authentication method 4. User Manager • is used to edit the list of persons or users which can use PCM 600 when an authentication method is selected

3.1

PCM 600 access The set up and the possibilities to organize PCM 600 access can be seen as a branch with three basic alternatives. For each of the three alternatives you have to set up information in the user manager and select a user category out of the list described by the category manager. Changes in the System Settings, Category Manager and User Manager can only be done by a user of the category type “System Engineer”. The used alternative is selected in the Authentication. Select the System Settings window to choose the authentication.

The User Manager window has four input fields. Three of them are used to define the access for a user for either PCM or Windows authentication. The field Real Name might be used to identify the user, when the user name is a short version of his name. The PCM authentication uses the following inputs to identify a user: • • •

User Name Set Password (optional) User Category. The user category is defined in the category manager. It belongs to the user name and is not part of the authentication check.

The Windows authentication uses the following inputs to identify a user: • • • •

User Name Windows Account. User Category. The user category is defined in the category manager. It belongs to the user name and is not part of the authentication check. Set Password is not used!

PCM authentication When the PCM authentication method is used a Login window pops up after start of PCM 600. The user has to identify himself with his user name and the password when it is used for access control.

Windows authentication In the Windows authentication method each user must have a different account on this PC. Only in this case a selective input is possible. In this case the user has already identified himself to the PC, when he started Windows. So a separate access control is not needed. A user can change his password, by entering his old password once, and then the new password twice. The system engineer can change passwords without knowledge of the old passwords.

Chapter 4 PCM 600 and CCT tool set for station engineering

Connectivity package support for PCM 600 PCM 600 is a tool which allows the user to include the engineering tool components for product families of ABB for transmission and distribution. In the way you are using ABB products it might be that you will have several sets installed using the concept of connectivity packages. How to install a new product package or to add an additional communication protocol is described in the documentation for PCM 600. To engineer the ABB IED 670 product family you must have enabled the use of these tools and protocols in the connectivity package manager. Please check that before you may start the PCM 600.

en05000561.vsd

Figure 30:

Connectivity manager: version selection window

Always use the latest version of a tool package or protocol. This can be easily done in the menubar Set Latest. In the above Connectivity Package Manager window the following packages are available •

It will be used to include the ied.ICD file of bay IEDs in the station.SCD file. It will be used, when the DRH tool is used to read the DR files from all IEDs running the IEC 61850 protocol. See IED engineering guide manual for more details about the disturbance report handler (DRH). IEC 61850 Connectivity Package - This package is needed for IED 670 products, which communicate with PCM 600 on Ethernet, TCP/IP and using elements of the IEC 61850 protocol. LON Connectivity Package - This package is not needed for IED 670 products. It is used for products using LON to communicate with PCM 600. IED 670 Connectivity Package - This package is needed in the latest revision to engineer IED 670 products. It contains the description of the IED 670 products. SPA Connectivity Package - This package is not needed for IED 670 products. It is used for products using SPA to communicate with PCM 600.

Chapter 4 PCM 600 and CCT tool set for station engineering

PCM 600 Set up communication link per IED 670 The communication between the IED 670 and the PCM 600 is independent of the used IEC 61850 communication protocol within the substation. It can be seen as a second channel for communication. When an additional link from PCM 600 to the IED 670 is requested see 'Engineering guide for IED 670 products'. The IP address used for the Ethernet channel with IEC 61850 protocol has to be filled in by the PST tool as part of IED 670 engineering.

5.1

PCM 600 Set up communication link per Generic IEC 61850 IED A Generic IEC 61850 IED (Gen-IED) can only communicate with the PCM 600 in the same way as the IED 670 products are when using the IEC 61850 protocol. That is only given for the disturbance file reading from the relays. The DRH tool is responsible for that task. For more details about the DRH tool see 'Engineering guide for IED 670 products'.

CCT views and windows The CCT tool set runs under the operation system Windows 2000 or Windows XP. It is expected that the user is familiar with the handling and use of the Windows platform. In this chapter only those items are explained and shown which are specific for CCT but still based on Microsoft windows methods. When you start CCT you will get a screen with the different panels but no contents. Once you have selected a project, you will get the possibilities to select different panels. The typical screen with an open project may look like shown in the figure below.

Project Navigator The Project Navigator shows the four sections in a SCL project in different levels of details. The known four sections are: •







Substation section - for information only. Only the sequence: Station > Voltage level > Bay is shown Communication section - for information only. Only the configured Subnetworks and their configured Access points are shown IED section - the tree structure can be expanded from > to: IED > LD > LN > DO > DA including the full extension of complex data objects - added DataSets, Report Control Blocks (RCB) and GOOSE Control Blocks are shown below the LN level when enabled to be included (normally below LLN0). - the configured Data objects (DO) are listed with all their Data attributes in the Attribute Editor within the IEC 61850 Data Engineering pane Data Type Templates - similar to the IED structure all existing LNodeTypes, DO Types, DA Types and Enum Types are shown in a tree structure. - The LN Types and their DOs are listed in the Attribute Editor within the IEC 61850 Data Engineering pane. The structure of DO Types, DA Types and Enum Types is not shown in the Attribute Editor

Properties The Object Properties window is a standard Microsoft window which allows to view and when needed to modify properties of the selected object. Due to the fact, that CCT operates only with the IED section properties should only be modified for the IED and the level below where useful and needed to be adopted. It has to be regarded, that most of the properties are under control of the configuration done by the station configurator PCM 600 or by the vendor of the IED. This is also valid for changes done for example in the given IED naming. It must be known that changing the IED name has influence on the substation section which is not supported by the CCT. The station configurator PCM 600 has control over the station wide naming and addressing rules.

Chapter 4 PCM 600 and CCT tool set for station engineering

Remark: The role of CCT is to do signal engineering and signal routing. The PCM 600 is responsible for the station configuration and naming within the project. The IEC 61850 Attribute editor may be used for monitoring and view of Logical nodes and their data objects and data attributes only. Even when it is possible to modify values, this may be done only in cooperation of the owner of this value which will be PCM 600 or the vendor of the IED. Remark Changes in the Properties may have influences to other SCL sections which are not updated by the CCT. When doing changes the position and influence of the attribute may be well known. They may have also influence on the IED configuration, which is vendors responsibility.

Output The Output window is shown on the bottom array of the CCT screen when selected. It is a log script which is used by CCT to list all activities, warnings, error messages etc. which come up during operation of the CCT. It might be needed and used when a task does not operate as expected. The information in the output list may give a hint why it does not operate etc. The Output view is not needed for normal operation and can be closed. There are two different views given: • •

Out - shows all messages unfiltered Log - shows only those messages with a category that is at least the same as the threshold defined in chapter 4, section 7.2 "Logger options".

Column Visibility Control (CVC) The CVC panel is available and can be used when “Report Control Engineering” or “Goose Control Engineering” is active. It allows to select only those columns which are of interest for signal engineering, like “Integrity Period”, “BuffTime”, etc. The list of selections shown when the Attribute Editor is selected are not foreseen for IEC 61850 views.

IEC 61850 Data Engineering This panel is surrounded by the above described various panels. For normal operation and after set up the Column Visibility Control the Output panel and the CVC can be closed. The IEC 61850 Data Engineering panel has four different tabs which are used for the different engineering tasks. • • • •

Pinning Clicking the symbol in a column header will fix or release the column to be shifted, when the spreadsheet is moved in horizontal direction. The column will automatically shift to the next right ascending position of fixed columns, when the columns left from the selected one are not fixed. So to get a correct sequence of fixed columns start to fix the columns from left to right.

58

CCT views and windows

Chapter 4 PCM 600 and CCT tool set for station engineering

Filtering This is the MicroSoft standard method of filtering in a column. Clicking the filter icon pops up a drop down list with possible choices. The first four choices are standard, the following one is the list of possible elements in this column. Selecting an element out of the list will mark all rows where the filter criteria matches in a way as described by the toolbar Filter action selection. Filter selection possibilities The Filter Action drop down list in the Toolbar allows to select a variant of how the filtered and not filtered rows should be marked and made visible: • •





HideFilteredOutRows 1. hides all rows which do not match the filter criteria DisableFilteredOutRows 1. shows all rows but disables the possibility to make changes (edit) in the rows which do not match the filter criteria AppearanceOnly - will leave all rows visible but colors the rows which do not match the filter criteria. The color is predefined. Default - is the same then “HideFilteredOutRows”

Filter with included filter bar When the Filter bar icon in the Toolbar is selected an additional row will be blended in below the column header row. This row enables to select the specific filter criteria from a drop down list, to enter the filter criteria right from the selection icon, to select an available element out of the list of elements available in this column and to reset the filter for this column. It is an extended but simple to use choice possibility for filtering. Column sorting To sort the sequence of columns to your own criteria can be done by the standard MicroSoft methods. Select the header element of a column and move it left or right to the position you want to have it. The position where it will be placed will be shown by two red arrows. In the same standard way it is possible to adjust the width of a column by selecting the right border of the column and move it. Grouping Grouping allows to sort the rows of a spreadsheet in groups. The different groups which will appear depends on the type and contents of the selected row for grouping.

Adding new rows and sub-rows or deleting a row When the spreadsheet allows the adding of new rows this is be seen in the bottom area below the spreadsheet. The button Add allows to add a row. All rows and sub-row possibilities are visible by select buttons per row type. To delete a row or several rows you have to select these rows by the standard MicroSoft methods (CTRL or SHiFT button pressed). Press the keyboard Delete key to delete the selected rows. A confirmation window will pop up and you have to confirm your action.

Sorting You may sort one or several rows in alphanumeric order by selecting the columns you want to sort and click the direction for sorting button in the Toolbar. Be aware that a sequential order as it was given by the spreadsheet before is lost (e.g. the sequence of data objects and data attributes in a complex data object structure). You have to deselect the spreadsheet and select it again to get the logical sequence back.

Text matching search In a long list you may search for a specific row. This is possible by searching in a selected column for the start character of the element you are looking for. Select the column in which you are searching. Type the first character of the element. The first row which matches will be highlighted. Each time you type the character the next row which matches will be highlighted.

It is also used when a failure occurs or when any other abnormal sequence occurs which may be clarified by ABB. The log file is requested by ABB when you communicate a failure or any other item. It is therefore requested to keep the log file history for this purpose. You may clear your hard disc from the burden of the CCT history from time to time. Ways to configure the log: •

Log Category - allows a selection from which message type upwards the messages should be listed in the Log window of the Output panel Log File Size - this is the size per file! A daily file of 1MB is hard to achieve. Be aware of the volume when you select a daily file. Clear the history from time to time! CCT extends the file name with the date when the file was started. So a daily log makes it easy to identify the file which is of interest. Append Log File - will continue to write in the existing file when a new session is started. The different parts of each session can be identified by date and time. Write Daily Log - we recommend enabling this function. A daily file makes it easier for search in a list as well to check other dates etc. Log File Path - the path is fixed and can not be modified Log File Name - the name is fixed and can not be modified

Chapter 4 PCM 600 and CCT tool set for station engineering

This is possible for six different Node types and for each node type up to three naming elements (Token) can be chosen. The available naming elements depends on the node type. You have to chose a Separator between the naming elements to get the string readable. Supported Node Types: •





Communication section - Subnetwork - Connected access points IED section - IED - Logical Node - Access point Data Type Templates - Logical Node type

The configuration of a Node Type can be done as follows: • • • • •



select a Node Type row or add a new one by clicking the Add button select a node type out of the drop down list select the various Token (1 to 3) and select a naming element out of the drop down list fill in the separators of your own choice when you leave the selected row, CCT detects the changes and starts to update the complete sections and the Project Navigator with the new presentation form. This takes some ten seconds depending on project size etc. Wait until CCT has finished the update. To see the result you have to close the option window and open the sections in the Project Navigator

An empty Token is left out. Make some examples to see the results and configure it to your demands.

Chapter 5 Set up a project in PCM 600

Set up a project in PCM 600 PCM 600 operates on projects. •





A project contains all information about the station configuration, the IEDs, the engineering of the IEDs when done with PCM 600, the uploaded and downloaded files and internal files produced by PCM 600 and the tool components used to run the project. A project is stored under the directory of PCMDataBase on the PC or workstation on which PCM 600 is installed. PCM 600 runs various projects under the control of PCM 600. But only one project can be active at a time. These imported projects are handled by the MSSQL$SERVER which is part of PCMDataBase. Projects may be grouped into two categories: - Engineering projects for IEC 61850 based stations. Engineering projects are focused on the complete engineering of a substation with its IEDs. The most practical size for a project is a substation. - System monitoring projects. System monitoring projects are focused on the monitoring information from the operating IEDs located in several substations. The most practical size for a project depends on the structure of the grid and customer's responsibility. This is described in the 'Engineering guide for IED 670 products'.

Tasks in an IEC 61850 station engineering project in PCM 600: • • • • • •

build up a plant structure for the substation place the bay IEDs to the voltage levels and bays place / check the bay IEDs to be connected to the IEC 61850 subnetwork engineer ABB IED products to generate their ied.ICD files load all other bay IEDs with their ied.ICD files export the station.SCD file for use in CCT



re-import the station.SCD file from CCT to update the ABB IED products and to generate the ied.CID files do signal engineering for the IEDs which are receiver of GOOSE messages.

Chapter 6 Set up a project in CCT

Import/export station.SCD files CCT as a tool for IEC 61850 signal engineering can do this tasks for a single IED or for a complete station with all IEDs linked to communication and defined in the substation section of the SCL file. This section describes the import and export of a station.SCD file.

save your project before select Tools > SCL Import/Export > Export SCL File an export window will pop up which shows a default place where CCT will store the station.SCD file. This is done in the directory “SCL” below the directory where the project is stored. This directory will be created by CCT if it does not exist. browse and select another place and/or name for the file when necessary press Export

The CCT will generate a station.SCD file by keeping those parts which are not touched by the CCT which is the Substation and Data Type Templates section. The communication and IED section may have been modified and extended by CCT. In addition CCT creates a set of ied.ccf files per IED in the project. These files include the SCL part which is of interest for the named IED only. They may be used to re-import the IED part to the IED configurator tool directly. These files are located at the same place as the station-SCD file.

Chapter 6 Set up a project in CCT

Import/export ied.ICD files CCT as a tool for IEC 61850 signal engineering can do this tasks for a single IED or for a complete station with all IEDs linked to communication and defined in the substation section of the SCL file. This section describes the import and export of an ied.ICD file. CCT can be used to configure DataSets and report control blocks (BRCBs) for a single IED before it is integrated in a station project. This makes sense when the IED is used more then once in the project. Import of the ied.ICD file to CCT, do DataSet and BRCB engineering and export it back allows to use the extended IED as a template for similar or same control or protection IEDs. In the actual version of PCM 600 it is only possible to include client IEDs in a station project via CCT.

Chapter 7 Station configuration with PCM 600 About this chapter This chapter describes how a station can be configured to fulfil the IEC 61850 requirements for signal engineering. The configuration of the substation from voltage level to bay and IEDs and the configuration of the communication structure is part of this chapter.

Set up a substation for IEC 61850

Chapter 7 Station configuration with PCM 600

Set up a substation for IEC 61850 PCM 600 organizes the structure of a substation in the Plant Structure window. The plant structure is used to locate each IED in its location within the electrical grid. It is a geographical image of the substation and the bays within the substation. You will build up the plant structure according to your project requirements. To do this PCM 600 offers some elements which build the hierarchical order from a Center down to the IEDs in a bay. The organization of the station according to IEC 61850–6 is done in PCM 600 on the basis of the 'Product related naming' (IEDName). This is shown in chapter 2, section 3.1 "The Substation section", figure 8. The following levels are available: 1. Project = Center (not used for the naming) 2. Region = when your grid might be subdivided into regions this level should be used in addition (optional) 3. Substation = Name of the substation (relevant for object designation) 4. Voltage Level = identifies to which grid type or part in the substation the IED belongs to 5. Bay = Bay within the voltage level 6. IED = selection of the IED which is used in the bay. Several IEDs are possible within a bay (e.g. one control IED and two protection IEDs) Level (2.) is optional all other level are a must to identify an IED. Once a plant structure is built the identification should be renamed by the names/identifications used in your project and to the specification for object identification as described in chapter 2 "IEC 61850 station engineering". Use the right mouse button to build the plant structure and to rename the elements.

PCM 600: Set up a plant structure by using Object Type window

Naming conventions for IEC 61850 The following definition is taken from IEC 61850–6 clause 8.4: The SCL model allows two kinds of object designation: 1. A technical key, which is used on engineering drawings and for signal identifications. This is contained in the attribute name as identification of each object. If this value is used as reference to an object, it is contained in an attribute name

87

Set up a substation for IEC 61850

Chapter 7 Station configuration with PCM 600

starting with a string denoting the reference target object type, and ending with the string Name. The technical key is used within SCL for referencing other objects. Observe that name is a relative identification within a hierarchy of objects. 2. A user oriented textual designation. This is contained in attribute desc. Attributes are not allowed to contain carriage return, line feed or tab characters. The semantics of desc shall also be relative within an object hierarchy. End of reference to the standard. PCM 600 takes care for these two possibilities. The two possible designations naming are available per object in the object properties for all hierarchical levels beginning with the station as highest level. The technical key is automatically generated by PCM 600 based on the rules and type specifications of IEC 61346 and the definitions done for substations by a technical committee. The technical key is shown in the Object Properties under “SCL TechnicalKey”. •





the start point is the station which is predefined by “AA1” where 1 is the index. Leave the station name untouched, even when it is the wrong station name. PCM 600 needs this start definition to build the technical key by itself. the second hierarchical level is the voltage level. The voltage level has to be selected in the Object Properties from a drop list. The corresponding character is automatically included in all objects. The drop list explains the voltage range for each character so it should be no problem to select the right character. The list is build on the definitions of the standard. the bay and the IED is appended with the coding defined in the IEC 61346 standard and the substation definition lists.

The “user oriented textual designation” is visible in the plant structure for each object. It is the name given by default or changed via the Rename possibility. It is shown in the Object Properties in the row Caption.

en06000029.vsd

Figure 55:

PCM 600: IEC 61850 signal designation concept

Set up a substation for IEC 61850

Chapter 7 Station configuration with PCM 600

In the above figure the bay named in the example “B_TR42” is visible in the object properties with the two designations. The technical key AA1C1Q1 can be read like this: • • •

AA1 = station 1 in the project C1 = voltage level from 380 to 420 kV Q1 = the first bay in the voltage level

Selection of object designation for the technical key As described before PCM 600 supports two possibilities for object designation. One of this two possibilities will be selected for the technical key in the SCL file when you export the station as station.SCD file. Using the designation according to IEC 61346 guarantees (Navigator Object Technical Key) that the naming is correct but maybe not useful in the naming your station is using. Using your own designation model (PCM Navigator Object Caption) is useful and can be done when the total length according to IEC 61850 (32 characters) is regarded and the designation for each level is unique. It should also be checked and notified when one of the user IEDs (most likely the client IEDs) have additional rules for the length of each level etc. Be careful and make a general concept for all partners in the project. See the standard IEC 61850–6 and chapter 2 "IEC 61850 station engineering" for more details.

1.2

PCM 600 selection of an IED This section includes the description how to select an ABB IED 670 product as bay IED. For the total capability see 'Engineering guide for IED 670 products'. A control or protection IED 670 can be delivered in two general versions: • •

open configuration IEDs pre-configured IEDs

When selecting an IED 670 a wizard is displayed which helps you to make the correct selection.

Open configuration IED An open configuration IED is described by: • •

the delivered hardware the delivered lists of selected functions

It includes: •

a set of ordered functions available for engineering the logic and operation of the functions

It does not include: • • •

any configuration of the application configuration program any engineering preparation for the IO hardware and IO signals no defined settings other then the default values

89

Set up a substation for IEC 61850

Chapter 7 Station configuration with PCM 600

It is important to understand, that the list of delivered functions correspond to the list of available function blocks in the IED itself. You can not use more function blocks than ordered. An IED is selected by: • •

• •

selecting the correct IED version 1.0 onwards type in the IP address for the IED to communicate with PCM 600. This IP address may be the same as used for the communication protocol (e.g. IEC 61850 or DNP 3.0 on Ethernet) but it must not be the same. This IP address is the link to the PCM 600 tool set. Browse to the folder where your order specific zip-file is stored. When you do not use an order specific configuration indicate that in the selection box.

Chapter 7 Station configuration with PCM 600

Select the “Replace... ” alternative. Because it is a Gen-IED it must be possible to replace the IED object types with the known Generic IEC 61850 IED object types. select “Allow overwriting... ” . The Gen-IED is a not known IED until now for the PCM 600. It must be possible to overwrite the default IED type with the type defined in the vendors IED.

The SCL file import starts and a progress window shows the status. A message will indicate the conclusion of a successful import. The IED name may not change by loading the file. Check and adapt the IED name to the projects definition with the Rename selection in the right mouse button menu.

Note The actual version of PCM 600 does not support the integration of client IEDs in the plant structure nor in the communication structure. This is actual only possible by adding the client ied.ICD file in the CCT and configure the communication section in the CCT with the additional client IED. See chapter 6, section 3 "Import/export ied.ICD files" how to do it.

Client IEDs can be integrated in a station project by CCT only. The communication structure can be checked by selecting it in the Project Explorer beside the Plant structure. By opening the tree structure it is visible that the OPC server of the PCM 600 itself is on top with the NETWORK below. All bay IEDs configured in the Plant Structure must be shown and connected to the NETWORK.

Chapter 7 Station configuration with PCM 600

Import/Export station.SCD files The IEC 61850 standard defines four file types in the sequence of engineering. These files have a different definition which is explained in IEC 61850–6 clause 7. Three of this file type are used in the engineering process for an IED 670. • • •

ied.ICD = IED Capability Description station.SCD = Station Configuration Description ied.CID = Configured IED Description

Export a station.SCD file The procedure is a follows: • • • • • •



select the station in the plant structure. See figure 62 select “Export System SCL...” with the right mouse button a standard Windows menu pops up to select a location. Choose a destination where the file should be stored and give it a name PCM 600 starts the process and will generate a new selection window. See figure 63 select “SCL Object Naming” variant for your project. See chapter 7, section 1 "Set up a substation for IEC 61850". check that the selection box “Export Private Section” is blank (not set). IEC 61850–6 defines in clause 8.2.6 the possibility to include a private structure of presentation in the SCL file for later reuse etc. This is actually not supported and not needed. start export. A progress window will show the export procedure which will take some time depending on the number of IEDs.

Import a station.SCD file When an exported station.SCD file is extended with the signal engineering by the CCT tool it is necessary to import the extended station.SCD file back and update the IED 670 products with the additional configuration. The procedure is as follows: • • • •

select the station in the plant structure. select “Import System SCL...” with the right mouse button a standard Windows menu pops up to select the file to be imported. Browse to the destination the file is stored and start the reading. a selection menu pops up which queries how the file should be handled during import. See figure 64. 1. The standard is the basic window as shown in the right screen-shot in figure 64 2. “Update PCM Structure from SCL” expects that the file is the one which was exported but now extended by configuration actions done in CCT. This is the normal case and set by default. 3. “Append SCL to PCM Structure” will append the information for each IED to the existing ICD part in the IED. This is useful, when the station configuration part is done on a basis ied.ICD file with no specific engineering or the ICD file does not exist for the IED 670 until now. 4. “Advanced Options” expand the window as shown in the left screen-shot of figure 64. 5. “Don't import ...” protects the existing IEDs in case the station.SCD file does not match the original configuration in PCM 600. 6. “Replace unknown ...” can be used when it is known, that the file includes additional IEDs which are needed. The IED of type “Generic IEC 61850 IED” is used to integrate these kinds of IEDs in the plant structure etc. 7. “Allow overwriting ...” should only be done when it is clear what happens and justified with the complete project.

Chapter 8 Signal engineering with CCT

IEC 61850 Attribute Editor The IEC 61850 attribute editor in this CCT version is not used for editing. It is only allowed and possible to view the structure and contents of Logical nodes and their data objects and data attributes. The organization of Logical nodes and their contents is under control and responsibility of the IED vendor. The structure and content of a Logical node is defined in IEC 61850–7–3 and IEC 61850–7–4. It describes the data objects, the data attribute classes and the base types as mandatory or optional elements of a Logical node. The IED products define their Logical nodes based on this standards. But these Logical nodes are described as LN types, because these LN contain only the used and available data objects etc. So each IED product will have its own set of used Logical node types. The SCL structure takes care of this in the Data Type Templates section where all used and available Logical node types, their data object types and their data attribute types and when given their additional base types of type Enumerated are included. The reference to the LN types is given in the IED section for each logical node by the LN type name as part of the Logical node identification.

The field is ready to accept a new name entry - regard the rules for DataSet naming according to IEC 61850–7–2 clause 11.2.2.1 Data Set Entries - lists all selected Logical nodes, Data objects or data attributes which are selected to be a member of the DataSet. - the used functional constraint (FC) is shown in brackets at the end - allows to remove (delete) a selected member out of the list. - the address (reference) of each selected FCD or FCDA is shown. The reference includes the logical device part below the server as start point. This gives the possibility to select any FCD, FCDA within the IED to be a member of the DataSet. In which way this is useful to get the right information sorted logically is a question to the project. - the selected Logical nodes with their data objects or the selected data objects directly are called Functional Constraint Data (FCD) or Functional Constraint Data attributes (FCDA) when the member is a direct data attribute IED Data Model - lists all Logical nodes within the IED with their data objects and data attributes in a tree structure - each element can be selected to be a member of a DataSet - allows, requests to select a FC to separate those attributes which will be member of the DataSet entry. Only FC = MX or ST are possible constraints for reports to clients. - allows to add the selected object to the list box of Data Set Entries. It will be then a member of the DataSet (Add) - allows to modify an already available member by overwriting its contents with the one of the selected object (Modify) Filtered Preview - This list box shows all data attributes of the selected FC of the selected object in the IED Data Model list box. These attributes will be transmitted in case one of the data attributes has forces a trigger to send the DataSet member.

Remark Analyzing all defined data attributes defined in IEC 61850–7–3 only data attributes with FC = MX or ST are marked with the capability to generate a trigger. And they belong to process data objects which contain the process information used at runtime. All other data attributes belong to control (commands), settings, functional configuration parameters or descriptions. These information are handled by other IEC 61850 communication services and are not part of a report.

Remark CCT has to update the contents of all four list boxes whenever a new object, item etc. is selected. To do this it reads the main part of data base to identify which objects etc. have to be presented. This takes some time and it is not directly shown by an hourglass or similar. A small help in this situation would be to start the Windows Task Manager and minimize it. The small dynamic icon in the low right corner shows when the CPU is active.

Chapter 8 Signal engineering with CCT

To configure a DataSet the following steps are requested in CCT: • • •

• • • • • •

select the Data Set Engineering tab in the IEC 61850 Data Engineering pane select the Logical node where the new DataSet should be located. This should be in normal cases the LLN0 of a LD. when requested and agreed in a project it is possible by the IEC 61850 standard to locate the DataSet in any LN. This is not allowed for DataSets which are used by GOOSE messages. These DataSets are only allowed in LLN0 ! press the Add button to add a new Data Set in the Data Sets list box give the DataSet a name. The name must be unique within the station to be able to identify it in the communication between a client and a server IED. select the FCD or FCDA which should be member of the DataSet in the IED Data Model list box. select the correct FC out of the list in the Func. Constraint list box click Add to add the FCD, FCDA to the Data Set Entries list box click Modify when the selected member of the Data Set Entries list box should be replaced or modified by the FCD, FCDA selected in the IED Data Model list box

Repeat the procedure for all DataSets which are needed in this IED. Continue to do it for all IEDs where additional DataSets are requested.

2.1

Predefined DataSet The IEC 61850 standard allows to have predefined DataSets which the vendor of an IED has included in his product. These predefined DataSets will be visible when you open an IED and will be listed under the LLN0. These DataSets may be modified or extended in a project. The possibility to do it must be announced by the vendor of the IED. ABB has defined four predefined DataSets for the IED 670 products: •

• • •

MeasFlt - includes those measured values which will be transmitted on dchg trigger given by a threshold value (deadband) StatIed - includes the behavior status of all Logical nodes StatNml - includes the trip signals (operate) of all protection Logical nodes StatUrg - includes the urgent alarms of the Logical nodes. The definition of what is urgent was done by ABB experts and may be checked by the project

When the Report Control Engineering pane is selected you will get a pane which contains a list with several columns and some or a lot of rows. Each row represents a BRCB description with all BRCB attributes which are of interest. When already client IEDs are linked to that BRCB this is visible by the icon element to expand the BRCB for next level rows. Each next level row contains the identification of a linked client IED. The five main steps to generate a BRCB are: •

give the BRCB a unique name according to the rules described in IEC 61850–7–2 clause 14.2.2.2 and the rules defined in the project select the DataSet out of the list of available DataSets for this BRCB. Always only one DataSet per BRCB. See the example in the figure above link the BRCB to the client IEDs which should receive these event telegrams. This is done by selecting the icon of the Logical node of the client IED (e.g. ITCI or IHSI) and link it to the name field of the corresponding BRCB by using the drag-and-drop method. Repeat this for all client IEDs which should receive the information. See the arrow in the figure above. configure the BRCB attributes to the standards defined in the project. do Update DataFlow by selecting this task via the menubar Tools > IEC 61850 Data Flow Engineering. CCT will now add the needed information in the SCL file in: - the IED section for the 'BRCB' in the Logical node defined for this DataSet and therefore for the BRCB. Should be normally LLN0 - the IED section with the identification of the connected client IEDs per BRCB

For the identification of a column the same text is used in the BRCB list and in the CVC. To see them in the CVC completely you have to select an element. The complete description will pop up, when there is more text then in the visible part. The sorting order for the column may be changed to your demands.

Each row represents a GoCB description with all GoCB attributes which are of interest. When already IEDs are linked to that GoCB this is visible by the icon element to expand the GoCB for next level rows. Each next level row contains the identification of a linked IED. GOOSE messages are not handled by the server. They are directly send by the communication handler as Unicast messages. The access to the Ethernet may need additional address information and timing parameters to monitor the correct sending. These parameters can/must be set per GoCB in an additional address definition row.
