2. GENERAL SYSTEM DESCRIPTION The SICAM PAS system is an op en, modularly-designed numerical system for energy automation. The specific functions of a power automation system are combined with those of a programmable logic controller system and include the communication possibilities of today’s IT-world. SICAM PAS has been designed specifically for the requirements of energy & power automation systems and is scalable d ue to its distributed architecture. The SICAM PAS power automation system provides a system solution for an efficient execution of all tasks required in a substation. SICAM PAS can be integrated into the existing communication structure of the substation, using standardized communication standards. SICAM PAS can also be used as a communication gateway. The full graphical process visualisation system SICAM PAS CC (CC: control centre) can be located directly in the substation and provides for easy control and monitoring. (See chapter 3 for a more detailed description of SICAM PAS CC). The CFC (Continuous Function Chart), a user-friendly graphical configuration tool for automation purposes is an option, included in the option is the specifically developed substation automation CFC function blocks. New devices can be integrated into the system and can be intuitively configured (via SICAM PAS UI). Especially using the possibility to adapt the configuration and the on-line settings (when the configuration is done on the SICAM PAS running the same hardware), without generation and loading, this makes the parameterisation and testing quicker and easier. For diagnostic purposes SICAM PAS has dedicated tools aboard. With using IT technology and with its integrated tools for test and diagnostics SICAM PAS is ready for the future, which a also secures the investment. The SICAM PAS power automation system provides innovative solutions for most diverse task definitions resulting from the use of distributed information systems in different locations. It is suitable for use both in interconnected and distributed switchgears of electric utilities and in the manufacturing industry. SICAM PAS has been designed as a modular, open system which complies with all widely used communication standards. In addition to this, it supports you in the implementation of projectspecific automation tasks in the field of substation automation and power automation. The SICAM PAS CC control and display system provides numerous options to realize your system management concept via individually designed user interfaces and operator actions. The consistent use of Windows technologies, convenient user interfaces and the operating logic of the system components ensure that newcomers become familiar with SICAM PAS within a short time.

3. SICAM PAS SYSTEM ARCHITECTURE Possible topologies of the SICAM PAS system are shown below. These do not necessarily fit together with the architecture on which this offer is based. Please see part C for the valid SICAM PAS architecture, as well as part B for the scope of delivery and service for this offer.
3.1.
SICAM PAS a system with distributed architecture
The SICAM PAS system consists of one Station Unit called “Full Server” (In a SICAM PAS hot-hot redundant system there are 2 “Full Server”) When wanting to increase the performance, numbers of connections ,system availability and topological reasons the SICAM PAS system can be extended with additional Station Units named “Device Interface Processor DIP“. • •
SICAM PAS is suited for the operation in a substation with one SICAM PAS Station Unit Can also work in co-operation with other SICAM PAS Station Units in a distributed system. The various SICAM PAS Station Units are in this case exchange information via a powerful Ethernet- LAN.
A powerful data distribution system for real time data enables the SICAM PAS system to allocate tasks to various SICAM PAS Station Units. These Station Units together form one SICAM PAS system and thus have a higher performance, system availability and more connections communication possibilities.

3.2. Hot-Hot (Control Master/ Monitoring Only) redundancy of a SICAM PAS system The availability of the SICAM PAS power automation system can be further enhanced in doubling the SICAM PAS Station Unit „Full Server“. The HMI server can also be built redundantly, as shown below and can serve several HMI clients.
Picture 3- redundant SICAM system (2 Station Units „ Full Server“ and redundant HMI server with 3 HMI clients)
The architecture consists of the 2 SICAM PAS systems in a hot-hot configuration. Both systems are acquiring data independently from each from the connected IED’s and/or satellite RTU’s. This hot-hot redundancy can be used only together with IED’s and satellite RTU’s which support dual/multiple master protocols (i.e. Profibus FMS, IEC 60870-5-101) or client server protocols as a server which can be accessed from dual / multiple clients (IEC61850) Both SICAM PAS “Full Servers” data bases are automatically yet independently updated from the field connected IED’s and satellite RTU’S (monitoring direction) No information exchange between the HOT-HOT SICAM PAS station units is required when no internal commands are generated (e.g. derivation SICAM PAS

from an indication) and there are 2 independent telecontrol connections to the control centre (which selects the active channel). In case internal commands are generated or only one telecontrol interface is available, an exchange of a status (“Control Master” / “Monitoring only”) between both SICAM PAS Station Units is a necessity to ensure that only one source is enabled to send commands and to switch the telecontrol interface to the Station Unit with the status “Control Master”. Possible locations for controls are: • • •
Local HMI SICAM PAS CC Remote control from a control centre Internally generated command (derivation, automatic sequence,…)
The following mechanisms are providing the necessary functionality of a single command source: •
SICAM PAS CC Remote Command
•
Internally generated command => CFC logic
•
=> Software redundancy function of WinCC => task of the connected control centre => Switching the telecontrol interface, when one is only available
The switching between of the status (“Control Master” / “monitoring only”) of the 2 „Full Server“ can be done via: •
•
Internal supervision function Done with CFC logic o o Exchange of status via OPC mechanisms Operator from SICAM PAS CC HMI place
Optional additional information can be generated and exchanged Verification of the status of the communication drivers to IED’s and satellite RTU’S connected to both Station Units => Switch over criterion: Station Unit 1 drivers not o.k. / Station Unit 2: drivers o.k. • •
Information to the control centre which Station Unit is the “Control Master” Life signal from both Station Units to the control centre

Especially in case of the LAN/WAN based telecontrol protocol IEC60870-5-104 where the substation is connected via a router (not in our scope) it is necessary that the owner of the substation implements all aspects of security (like firewall …) in the used router in order to protect the substation against unauthorized access. Satellite RTU’s can be connected to the SICAM PAS system via the telecontrol protocols IEC 60870-5-101 and/or DNP V3.00 (level 2). The transmission rate of the implemented protocols can be at maximum: • • • • •
IEC 60870-5-104 (Slave) 10/100 MBit/s IEC 60870-5-101 (Slave) up to 38,4 kBit/s (balanced and unbalanced mode) DNP V3.00 Level 2 (Slave) up to 38,4 kBit/s IEC 60870-5-101 (Master) up to 38,4 kBit/s (balanced and unbalanced mode) DNP V3.00 Level 2 (Master) up to 38,4 kBit/s
The implemented functions of these protocols and the rules for exchanging the data between the SICAM PAS system and the control centre are described in the attached protocol description / interoperability list.

7.2. Communication with IED’s and satellite RTU’s The maximum number of IED’s and/or satellite RTU’s which can be connected to a SICAM PAS system is 150, independent o f the used communication protocol (IEC61850, IEC 60870-5-101, IEC 60870-5-103, DNP V3.00 (level 2), Profibus FMS / DP or Modbus-RTU). The following protocol options (available per order code) for communication to IED’s and satellite RTU’s are available for the SICAM PAS system: IEC 61850
IEC 61850 is the international standardized communication protocol in a substation for connecting IED’s and devices within a substation using Ethernet MMS. IEC 61850 also supports a direct data exchange (broadcast, multicast) between IED’s and therefore allows for example system interlocking without a central unit.
Profibus FMS
Most SIPROTEC 4 bay control and protection relays can be connected to the SICAM PAS Station Unit using Profibus FMS. Within Profibus FMS many features which a re later found in the IEC61850 can already be used.
IEC 60870-5-103
Many of suppliers of protection relays, bay controller, and other IED’s support this protocol and can be connected to the SICAM PAS.
IEC 60870-5-101
(Master) the international standardized protocol IEC 60870-5-101 is used for the connection of satellite RTU’s. ‚balanced‘ and ‚unbalanced‘ modes are supported. For the connection of satellite RTU’s automatic dial-up communication is also supported. The establishment of the connection to the satellite RTU can be done cyclically and driven by event (e.g. to send a command). In monitoring direction the establishment of the connection can also be done cyclically and driven by events. Analogue and ISDM modems can be used; it is also possible to use a GSM modem in the substation. For the communication to the satellite RTU’s Backup modems can also be used. " other satellite RTU’s can therefore be connected when the “standard modem” is busy.
PROFIBUS DP
PROFIBUS DP is a powerful field bus protocol using the Tokenassingprocedure. This protocol is mainly used in the process automation area and also in automation systems for energy- and gas- substations. For simple applications, where functions like time synchronization and transmission of fault recording is not required, SIPROTEC 4

relays can be connected to the SICAM PAS Station Unit using Profibus DP.
Additionally connecting IED’s with DNP V3.00 (level 2) and Modbus RTU protocol is possible.
Examples for the connection of IED’s Depending on the implemented functions and the technical specifications of the hardware and the interfaces, the following combinations may be implemented: IEC 61850 SIPROTEC 4 protection relay SIPROTEC 4 Bay Processing Unit Protection devices of third party manufacturers • • •

MREC AGH GHALA 63/20kV Substation Automation SICAM PAS Solution, System Description
With the OPC Server SICAM PAS process variables can be read and written from OPC clients which arelocated either in the same system or connected via TCP/IP to the SICAM PAS system. Using these OPC mechanisms it is for example possible to connect a third party HMI. The OPC Server is part of the SICAM PAS basic package. The OPC Client can read and write data from other OPC-Servers. An application example is the data exchange between the SICAM PAS Station Unit and the SIMATIC automation systems.
7.4. Communication with the HMI system The process visualization and control System SICAM PAS CC is connected via LAN connection (Industrial Ethernet TCP/IP) to the SICAM PAS Station Unit(s). The SICAM PAS CC visualization and control system can be configured as: • Single User System (1 SICAM PAS CC to control 1 SICAM PAS system) • Multi User System (1 SICAM PAS CC to control several SICAM PAS systems) • Multi User System using client/server architecture The SICAM PAS CC Server can be redundant Please see chapter 3 for more detailed description of the SICAM PAS CC visualization and control system and the system requ irements.
8. SYSTEM SAFETY Reliability and safety requirements as required in a substation automation system are fulfilled to a high degree by the SICAM PAS system. Electromagnetic compatibility of SICAM PAS electronic components is also given particular attention. SICAM PAS promptly signals faults because it has continuous running safety check running in the background. This ensures that the operation /maintenance personnel can locate the faulty system components more quickly. •
Interruption of power supply
The SICAM PAS system automatically reboots after an interruption of the supply voltage. All the parameters are securely stored in the real-time data base and all applications are started as “services” automatically in the same state as before the interruption. The SICAM PAS system is designed to be maintenance free, i.e. no buffer ba tteries are required and there is fan -free operation.
•
Communication
Faults in data transmission caused by electromagnetic influences, earth potential differences, ageing of components or other disturbances or noise sources on the transmission channels, are reliably detected. The safety procedures of the protocols detect:

A telecontrol fault group indication can be parameterised from individual information items and transmitted as a group indication to the control centre, logged or used for signalling at the cubicle. Using the graphical automation tool CFC single faults can be easily and comfortably grouped in a user friendly way, using the structured text function of the automation tool of SICAM PAS.
Our scope of supply ends with the physical telecontrol interface of the SICAM PAS Station Unit(s). The connection to a public net using Web-browser or WAN connections via router is within the responsibility of the substation owner. Especially in case of the LAN/WAN based telecontrol protocol IEC60870-5-104 where the substation is connected via a router (not in our scope), it is necessary that the owner of the substation implements all aspects of security (like firewall …) in the used router in order to protect the substation of unauthorized access. At the latest after commissioning or transfer of the equipment for operation Siemens will not be able to ensure that all security relevant patches can be installed, therefore Siemens must reject the responsibility for the protection against unauthorised access.

9.2.1. Configuration and Parameterization The clearly structured configuration interface provides you a comprehensive overview of your system parameters. Import and export functions allow the exchange of configuration data. This reduces the expenditure and error sensitivity during the configuration and parameterization of a system. The elements of the user interface can be arranged according to the requirements of the individual user. You can specify that continuously required table columns are always shown in the corresponding view, whereas non-required columns are hidden. The settings are maintained also after a restart of the program. Sorting and filter options provide for increased transparency and convenient parameterization. System-specific automation functions are graphically configured. To do so, you use both default logic functions and specific power automation function blocks. Your parameter entries are immediately checked for plausibility. Tooltips provide information on the permissible values or on the value range. In addition to this, the user is supported by a context-sensitive online help. It is not necessary to explicitly generate the configured and parameterized data for the runtime environment. SICAM PAS UI - Configuration structures the parameters in the individual views:

MREC AGH GHALA 63/20kV Substation Automation SICAM PAS Solution, System Description
Importing configuration data You can import the configuration data of bay and protection devices in the DBF, XML or SCD format, whereas configuration data of substations are imported in the XML format. For IEC 61850, all devices included in an SCD file are imported and created automatically within the framework of the SCD file import. Export of configuration data Control center
Configuration data created via SICAM PAS for the connection of your station to higher-level control centers via IEC 60870-5-101 can be exported in the XML format and then imported by the control system.
SICAM PAS CC
Configuration data required for the process visualization via SICAM PAS CC are exported in the PXD format. Afterwards, these data are imported by the SICAM PAS Wizard and used for the generation of the control and display interface of your SICAM PAS system.
Exchange of configuration data via OPC If your SICAM PAS system works as a n OPC Client, you can apply data of the corresponding OPC Server. In this context, the OPC Browser displays in a comprehensive manner which information is available and which information is already used. This is a convenient method to extend or reduce a n already performed data selection.
9.3. Automation Functions The SICAM PAS automation blocks provide a comprehensive tool allowing individual solutions of operational automation tasks. Automation functions are formulated via CFC or Structured Text (ST). CFC allows the graphical connection of function blocks. In addition to usual link blocks such as AND, OR, NOR, etc., you can use a comprehensive library of system-tested power automation function blocks. In this way, you can realize typical task definitions such as

9.7. HMI In the SICAM PAS system, SICAM PAS CC performs the control and display functions of the process information of your system. In this way, functional and spatial contexts of your system components are represented conveniently in overview and system diagrams. The logging of status changes of your process information and operator actions in the correct time sequence is performed via message lists such as the alarm and event list. You can intervene into the process and control it from system diagrams. System data such as messages and measured values can be logged and saved in freely definable archives. The assignment of specific authorizations, the possibility to use bay and telecontrol blockings, different switching modes and the consideration of switching authorities complete the control functions. For more information on these functions. The communication with the SICAM PAS is performed via Ethernet (TCP/IP).

Import After the creation of a station, you use the SICAM PAS Wizard to import SICAM PAS information configured and parameterized with the SICAM PAS UI - Configuration tool. The import includes: •
Import of the SICAM PAS tags to the SICAM PAS CC tag management.
•
Import of the SICAM PAS messages to the SICAM PAS CC alarm logging.
•
•
Import of the SICAM PAS measured values and metered value to the SICAM PAS CC tag logging. Creation of the SICAM-specific structure tags and of the required internal tags (variables).
Initialisation The SICAM PAS Wizard initializes the project. Within the framework of the initialization: •
the SICAM symbol library is imported.
•
the SICAM-specific alarm logging is created.
•
the SICAM text library is created.
The initialization can be performed independently of the SICAM PAS data import. In this way, you can start the configuration of the SICAM PAS CC project before the completion of the project via SICAM PAS UI - Configuration. The activities of the SICAM PAS Wizard are logged in the SICAM Report which provides you with detailed information on the success of the activities or on error messages and warnings.
SICAM PAS symbol library The SICAM PAS symbol library includes •
Objects for the representation of the switching devices
•
Objects for the visualization of measured and metered values
•
•
SICAM PAS
Message window templates for alarm logging (templates for the event list, warning message list and the protection message list) Control elements e. g. for the control of the switching authority, for synchronized switching, etc.

When creating your system diagrams, you simply move these graphical objects via Drag&Drop from the library to your diagram. As a next step, you connect them with the information parameterized via SICAM PAS UI - Configuration. Switching device objects IndustrialX Controls are used in SICAM PAS for the visualization and control of the switching objects. IndustrialX Controls can be used in the multi-client and Web n avigator environment. The SICAM switching device objects for circuit breakers and disconnectors support four representation modes each: •

If other representation options are required, you can assign the different states to bitmaps which have been defined for this purpose. The GIF image format ensures optimum display performance.
Bay overview objects Bay overview objects are a vailable in the SICAM PAS symbol library. These IndustrialX Controls visualize the switching status of the overall bay. During the pa rameterization, you select the individual switching devices for which the color is to change when the switching state changes. In this way, bay overview objects increase the information content of your overview diagrams.
Status di splay The status display graphically visualizes the information statuses Not topical, WIN CC status not OK, Bay blocking, Telecontrol blocking a nd Manually updated. Via a context menu, you can display the current status of a selected information object in text form. The color representation of the individual status in the graphical representation can be selected for the individual user.
Dynamizations If a distinction must be made between synchronized and unsynchronized controlling of a switching device, you can define additional dynamizations in the switching device object. In this way, the control dialogs are extended and the control method can be chosen in runtime. Some SIPROTEC 4 bay devices support synchronized s witching. If the switching device objects are only used in monitoring direction (missing entry of the control variables), no control dialog is output.
Two-step control ling The switching devices are controlled in two steps with the IndustrialX Controls. The switching direction is selected in the first step, whereas the command output is initiated in the second step. If a subdevice supports the Select before Operate function, it can be combined with the two-step method.

EnableSwitching Depending on other tabs (variables), control dialogs can be prevented in runtime. As an example, this feature is used if the switching authority changes between several operator terminals of a SICAM WinCC Client/ Server configuration.
PermissionLevel In the WinCC properties dialog, you can specify the user authorizations to determine which operator actions or parameterization tasks may be performed by a certain operator.
LabelButtonOn With this parameter in the WinCC properties dialog, you can specify object-specific texts for runtime dialogs e. g. Step up/Step down for the transformer control.
Language adaptation The default version of SICAM PAS CC provides German and English configuration and runtime dialogs. However, all texts used in these configuration and runtime dialogs are stored in text files. For this reason, they can be translated conveniently to other languages.
SICAM PAS CC alarm logg ing - message list s In the SICAM PAS CC message lists, the incoming messages are logged with the absolute time stamps formed in the bay devices or substations. The time stamp and the message state are completed by additional information. Examples of additional information: Cause, event source, status information, protection times, etc. Besides the values IN/OFF and RAISED/CLEAR, the value display also comprises fault positions (double-point indications) and bit pattern indications. Value texts can be parameterized for the individual message, such as Step up/down. You can create up to eight different value text groups. Command output indications are logged in addition to process indications. In the alarm list, you can select which indication status is to be ackno wledged. RAISED state CLEAR state RAISED and CLEAR state. RAISED indications remain in the alarm list until the corresponding CLEAR indication and the acknowledgement which might be required. • • •

Status of the devices SICAM PAS CC visualizes the status of the device connections to the SICAM PAS Station Unit. If the connection is lost, the color of the switching device objects and measured-value objects in the diagram changes. In addition to this, the device status can be logged in the message lists.
SICAM Valpro SICAM Valpro is an optional component for the processing, display and printing of archived measured and metered values. It is based on the SICAM PAS CC archive system (SIMATIC WinCC tag logging). SICAM Valpro displays archived values in a graphical or tabular representation. The following values are evaluated: •
Original values
•
Maximum and minimum values in different time intervals, e. g. 15 minutes or hourly values
•
Power factors
•
Sum/difference values of metered values in different time intervals.
Groups can be defined for the representation and measured values can be assigned to the groups. The diagram representation can be defined freely with regard to many properties, such as the curve type or the background. Curve properties can be defined specifically for an individual curve. Measured-value curves are represented analogous to the fault record evaluation. The tabular representation of the archived values can be added to the graphical representation or positioned independently. The cursor po sition and the first visible table row correlate. Graphical representations and tables can be output on a printer. Tables with archive data can be exported in the CSV format, whereas text reports can be exported in the text format. In this way, they are available for further processing in other programs (such as Excel). SICAM Valpro can be used on the SIMATIC WinCC Server or clients. As an alternative, it can also be executed independently of SIMATIC WinCC. For the offline evaluation, you require group files which you have created with SICAM Valpro in the SIMATIC WinCC environment. SICAM Valpro requires an individual authorization for each computer.

9.7.4. Substation Control Functions SICAM PAS provides a series of functions tailored to the requirements of substation control tasks. These include: •
Switching authority
•
Bay blocking
•
Telecontrol blocking
•
Time synchronization
•
Fault recording
9.7.4.1. Switching Authority In distributed systems, the switching authority defines which layer has the switching authority. The bay control layer, the station control layer or the control center layer can have the switching authority. Besides local/remote switching by means of the key switches of the bay devices, a distinction between local and remote control can be made on the station control layer.

The switching authority can be defined for the specific channel, i. e. one telecontrol channel has the switching authority, whereas the others and the local control have no authority.
9.7.4.2. Bay Blocking To perform maintenance tasks on a feeder, it might be useful to interrupt the data exchange in control and monitoring direction with the bay devices concerned. The bay blocking can be enabled or disabled for a specific device. If the bay blocking is set, value changes of the process information and the status information are not transmitted. The bay blocking is visualized by the graphical representation variants of the switching objects. Setting and clearing of the bay blocking is logged in the event list of the SICAM PAS CC HMI. In addition to this, you can specify during the parameterization whether the information affected by the bay blocking are a lso marked individually as Not topical in the event list.
9.7.4.3. Telecontrol Blocking To perform maintenance tasks in a station, it might be useful to interrupt the communication with higher-level control centers in the control and monitoring direction. The telecontrol blocking can be enabled or disabled for a specific channel. If a telecontrol blocking is set, the local control has the full volume of information available. Setting and clearing of the telecontrol blocking is logged in the event list of the SICAM PAS CC control and display system.
9.7.4.4. Time Synchronization If your SICAM PAS Station Unit is to take over the time synchronization of bay devices, substations and SICAM PAS CC, this can be performed via a DCF 77 or GPS time signal receiver manufactured by the Hopf company. The SICAM PAS Station Unit itself can also be synchronized via this time signal.
9.7.4.5. Ethernet station bus In the case of system configurations with an Ethernet station bus (IEC 61850), a separate time master can be used on the Ethernet which synchronizes all connected devices, the SNTP clients, as an SNTP server (Simple Network Time Protocol).

In this case, the SICAM PAS Station Unit also acts as the SNTP client with regard to the time synchronization. Nevertheless, it performs the synchronization of the devices connected to the SICAM PAS Station Unit via other protocols.
9.7.4.6. Fault Recording For protection devices connected to a SICAM PAS Station Unit via the PROFIBUS FMS, IEC 61850 or IEC 60870-5-103 protocols, the fault records created in these devices are transmitted automatically. These fault records are archived automatically in communicationspecific directories on the fullserver or DIP. The fault records transmitted can be evaluated using SICAM Recpro. SICAM Recpro consists of the following components: •
SICAM Recpro Explorer for the management and evaluation of fault record archives in combination with an evaluation program.
•
SICAM Recpro Collector for the generation and management of a central fault record archive
•
ComtradeView for the visualization of fault records
SIGRA 4 can be used for a comprehensive and sophisticated fault record analysis. This analysis tool calculates further tags and graphically represents the fault records in different views.
