SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends Description Application The 7SD610 relay is a differential protection device suitable for all types of applications and incorporating all those functions required for differential protection of lines, cables and transformers. Transformers and compensation coils within the differential protection zone are protected by means of integrated functions, which were previously to be found only in transformer differential protection. It is also well suited for complex applications such as series and parallel compensation of lines and cables. It is designed to provide protection for all voltage levels and types of networks; two line ends may lie within the protection zone. The 7SD523 is used when more than two line ends lie within the protection zone. The relay features very highspeed and phase-selective short-circuit measurement. The unit is thus suitable for single and three-phase fault clearance. The necessary restraint current for secure operation is calculated from the current transformer data by the differential protection unit itself. Data communication for differential current measurement is effected via fiber-optic cables or digital communication and telephone networks, so that the line ends can be quite far apart. Its special product characteristics make it particularly suitable for use in conjunction with digital communication networks. The units measure the delay time in the communication network and adaptively match their measurements accordingly. The units can be operated through leased lines employing twisted telephone pairs up to a max. distance of 8 kmby means of special converters and also through leased digital telephone lines (64/128 kbit) or switched systems (50 Hz networks). The serial communication interfaces for data transmission between the ends are replaceable by virtue of plug-in modules and can be easily be adapted to multimode and monomode fiber-optic cables and to leased lines or switched lines within the communication networks.

Extremely fast, selective and sensitive protection of two-end lines can now be provided by means of these units. Maximum service life and reliability The 7SD610 hardware is based on 20 years of experience gained by Siemens in design of numerical protection units. Advanced technology and a powerful 32-bit microprocessor are employed. Manufacture is subject to stringent quality standards. Particular attention was paid to electromagnetic compatibility and the number of electronic components has been drastically reduced through the use of large-scale integrated circuits. The software design incorporates our accumulated experience and makes use of the latest technological developments. High reliability is assured by use of object-oriented high-level programming and consistent quality control. A member of the SIPROTEC 4 family The 7SD610, which is a member of the SIPROTEC 4 unit family, is notable for the uniform design and the high degree of functionality, which represents a fully new quality level in protection technology. The local operation interface was designed on the basis of ergonomic requirements. Particular value was attached to readability of the multi-line backlit display. The most important protection parameter settings can be entered intuitively by means of the integrated membrane keyboard. Bymeansof the DIGSI 4 PC operating program, all the settings can be entered right at the unit and user support is provided for operational and fault analysis. Integrated measuring and control functions In addition to the protection functions, the 7SD610 also incorporates measuring, control and monitoring functions and thus contributes to economical plant and network operations control.

Backup protection The unit can also be employed as backup for the distance, in which case the tele-protection comparison of the distance relay can be effected via the communication link of the differential protection. It is thus possible to reduce the operating costs of communication for a protection section. Additional functions In addition to differential protection, the 7SD610 also incorporates a number of additional functions: − Three-stage overcurrent protection (can also be configured as backup or emergency protection) −  Instantaneous high-current tripping, optionally with interrogation of the switchgear status of all the line ends. −  Phase-selective breaker intertripping by means of the differential protection or of an external protection unit. − Single or three-pole autoreclosure using either conventional procedures or new adaptive technology.   − Overload protection − Genuine real-time mode for both units with synchronization via the communication link.

4 remote tripping commmands initiated via binary inputs

Programmable logic The integrated logic functions allow the user to implement customized automation functions via the graphic user interface. It is thus also possible to generate user-defined messages. The logic is suitable for protection applications with stringent real-time requirements, but it is also suitable for tasks with not so stringent real-time requirements, e.g. control and measuring functions. Differential protection communication / local and remote communication The 7SD610 has been provided with a number of different serial communication interfaces for various tasks: − Front serial interface for connection of a PC with the DIGSI 4 operating program or a standard browser.

−  IEC system interface for con-

Fault indications

nection to a substation control and protection system using the IEC 60870-5-103 protocol. This interface is prepared for other protocols such as Ethernet, PROFIBUS FMS/DP and DNP 3.0. −  Serial service / modem interface for connection of a PC or modem respectively. Direct connection or centralized operation via the RS485 bus or star coupler. Local / centralized or remote operation by means ofDIGSI 4 or a standard browser. − Time synchronization interface for IRIG-B or DCF 77 signals. The signal level is adjustable. −  The 7SD610 relay is also provided with a fiber-optic interface for communication with the neighboring differential protection relay.

Data for the last 8 faults are stored in the unit. The latest fault overwrites the oldest fault. The fault indications have a time resolution of 1 ms. They thus provide a detailed log of the fault event sequence.

Operational measured values In order to facilitate system management and commissioning, all the relevant measured values are shown as primary and secondary values with their corresponding dimension and associated with the objects to be protected. In addition the current and voltage measured values of the unit at the remote end of the line are also displayed. The measured values can be read on the display or by means of DIGSI 4. A distinctive feature of the 7SD610 is graphic display of the local and remote measured values in a browser window. Indications The 7SD610 makes available detailed data for network fault analysis and for supervision during operation. The indications are stored in nonvolatile memory and are thus immune to failure of the auxiliary voltage. Since the units at the ends of the line are time-synchronized, the time stamps for the operational event and fault event messages are identical.

Operational indications All indications not directly related to a fault (e.g. operator control action, monitor signals, unit start-up), are stored in the status indication buffer. The time resolution is 1 ms. Spontaneous indications Indications can be displayed spontaneously as they are generated in the process in an indications window by means of DIGSI 4. Fault recording An instantaneous value recorder with a time resolution of 1 ms is provided. A maximum of 8 fault records can be stored in the non-volatile fault record buffer, which is immune to failure of the auxiliary voltage. The total time period of a fault record is5 s. If, in addition to the CTs, VTs are also connected to the 7SD610, the fault records contain the current and the voltage during the fault. The calculated differential and restraint currents are shown in the fault records, so that the relevant tripping parameters are immediately visible. The fault records of both ends of the line are time-synchronized. The fault records of the line ends can be displayed in an integrated time-synchronized depiction by means of the SIGRA 4 graphic analysis program. Evaluation of fault records is thus considerably enhanced to a degree previously associated only with fault recorders. Commissioning program Currents and optionally the voltages are displayed graphically with absolute value and phase by means of a special program, which runs in conjunction with a standard browser on the PC. In addition, local and key measured values of the communication links are displayed.

The differential and restraint currents are also displayed as measured values in the tripping characteristic. Control Control of circuit-breakers and disconnectors (electrically / motor-actuated disconnectors) is possible by means of the integrated control functions via the integrated operator panel, the binary inputs and using DIGSI 4. The 7SD610 incorporates the complete scope of control functions of the SIPROTEC 4 unit family. Time synchronization A battery-buffered clock is provided as standard. The clock can be synchronized by means of a serial signal at the timesynchronization interface (DCF77, IRIG-B via a satellite receiver), via a binary input (1 minute pulses) or via the substation control interface. Every message is provided with a real-time date and time tag with a resolution of 1 ms. A special feature of the 7SD610 allows time synchronization via the communication links. It is thus sufficient if one unit is externally synchronized with respect to time. Timekeeping of the other unit is corrected and synchronized with his master unit. Assignable binary inputs and contact outputs Binary inputs, binary outputs and LEDs are assignable with indications, user-specific and independent of one another. Selectable function keys Four function keys can be assigned to permit the user to perform frequently recurring actions very quickly and simply. Typical applications are: jumps to a given position in the menu tree in order to display the event log or to perform automatic functions, such as ”Switching of circuit-breaker”, hot line tagging, reclose blocking, etc.

Continuous self-monitoring The hardware and software components are continuously monitored. If abnormal conditions are detected, the unit signals them immediately. In this way, a high level of safety, reliability and availability is achieved. In addition, the 7SD610 is provided with high-speed current monitoring stages, which on phase failure or implausible current measurement in the analog stage immediately block the protection unit and thus effectively prevent possible consequential overreaction by the differential protection unit. Reliable battery monitoring The internal battery is used to backup the clock, event logs and fault recording in the event of a power supply failure. Its function is checked by the processor at regular intervals. If the capacity of the battery is found to be declining, an indication appears on the display. Routine replacement is therefore not necessary. All protection and other setting parameters are stored in the FlashEPROM, and therefore not lost if the power supply or battery fails. User-friendly local operation Many advantages can already be found on the clear and user-friendly front panel: Positioning and grouping of the keys support the natural operating process. A non-reflective backlit display. Programmable (freely assignable) LEDs for important indications. Arrow keys ensure an easy navigation in the function tree. Operator-friendly input of the set values via the numeric keys or DIGSI 4. Four programmable keys for frequently used functions at the push of a button.

SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends DIGSI 4 Operating program DIGSI 4 the operating program for SIPROTEC 4 units The PC DIGSI 4 operating program is the user interface for the 7SD610 units. It is a modern PC operating program that is usable with Windows versions 95/98/ NT4.0. DIGSI 4 is the tool used for configuration, programming and the comfortable user interface for the 7SD610 and other SIPROTEC 4 relays. With the additional program SIGRA 4 comprehensive fault analysis is possible. The DIGSI remote program offers a remote access via modem to the relay with it´s rear service/modem interface. Simple setting of the protection The required protection functions can be easily selected from the complete range of functions provided. As a result, the functional clarity in the further menus is enhanced. The newly introduced display of primary values (setting values are referred to rated values of the object to be protected) allows standardization of the setting values. Conversion into secondary values and loading into the protection unit are pushbutton operations.

Routing (marshalling) matrix Routing is transparent thus ensuring that you can always clearly assess the situation. The matrix clearly displays, for example, which LEDs, binary inputs and relays are connected to which internal signals. By means of a click, connections can be made even up to the substation control system. It is possible, for example, by making use of the filter functions, to display only marshalled information. Moreover, the viewpoint can be altered. In the binary output view (relays), the tripping matrix is displayed in a clear manner. SIGRA 4: Universal program for evaluation of fault records Fault records stored in the protection unit can be visualized in a straighforward manner and evaluated. Harmonic and individual measuring points can be easily calculated, phasor and circle diagrams can be displayed, in addition to numerous other functions.

SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends Communication With respect to communication, particular emphasis has been placed on high flexibility, data security and use of customary standards in the field of energy automation. The concept of the communication modules allows interchangeability, on the one hand, and, on the other hand, is open for future standards (e.g. Ethernet).

Master control unit

Local PC interface The PC interface provided on the front panel on the unit allows rapid access to the parameters, status and fault event data by means of the DIGSI 4 operating program. Use of this program is particularly advantageous during testing and commissioning.

Typical applications employing fiber-optic cables or communication networks Three applications are shown in Fig. 17. The 7SD610 differential protection relay is connected to the current transformers and to the voltage transformers at one end of the cable, although only the currents are required for the differential protection function. The voltage connection improves, among other things, the frequency measurement and allows extension of the measured values and the fault records. Direct connection to the other units is effected via monomode fiber-optic cables and is thus immune to interference.

1) Available as of 05/2001

Two different modules are available, one of which covers distances of up to10 kmand the other up to35 km. In the case of direct connection via fiber-optic cables, data communication is effected at 512 kbit/s and the command time of the protection system is reduced to 15 ms. Parallel compensation (for the load currents) is provided within the protection zone of the cable. By means of the integrated inrush restraint, the differential protection relay can tolerate the surge on switching-on of the cable and the compensation reactors, and thus allows use of sensitive settings under load conditions.

The other example shows two differential units. The data exchange is made via a communications network. 7SD610 offers many features to reliably and safely handle data exchange via communication networks. Depending on the bandwidth available in the communication system, 64 kBit, 128 kBit or512 kBit can beselected for the X21 interface, whereas the G703.1 interface works with 64 kBit/s. The connection to the communication converter is effected via cost effective 820 nm interface with multimode fiber. This communication converter converts the optical input to electrical signals.

The third example shows the relays being connected via a twisted telephone pair. Data exchange and transmission is effected via a leased line of a max. length of 8 km. Here a transformer is in the protected zone. In this application 7SD610 is set like a transformer differential relay. Vector group matching and inrush restraint is provided by the relay.

SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends Functions Differential protection (ANSI 87L, 87T) The differential protection function has the following features: • Measurements are performed separately for each phase; thus the trip sensitivity is independent of the fault type. • An adaptive measurement method with high sensitivity for differential fault currents below rated current offers the detection of highly resistive faults. This trip element uses special filters, which offer high security even with high level DC-components in the short-circuit current. The trip time of this stage is about 35 ms, the pickup value is about 10 % of the rated current. • A high-set differential trip stage which clears differential fault currents higher than the rated current within 15 ms offers fast tripping time and high-speed fault clearence time. A highspeed charging comparison method is employed for this function.  When a long line or cable is • switched on at one end, transient peaks of the charge current load the line. To avoid a higher setting of the sensitive differential trip stage, this setpoint may be increased for a settable time. Under normal operating conditions, the relay is switched automatically to the sensitive setting. • A new feature of the unit is parameterization of the current transformer data. The unit automatically calculates the necessary restraint current by means of the previously entered current transformer error. The unit thus adaptively matches the working point on the tripping characteristic so that it is no longer necessary for the user to enter characteristic settings. • Different current-transformer ratios may be employed at the ends of the line. A mismatch of 1:8 is permissible. The tripping values of the unit are referred to a nominal operating current previously entered by the user.

  Siemens SIP5.4 ⋅ 2001

• Differential protection trip-

ping can be combined with overcurrent pickup. In this case pickup of the protection relay is initiated only on simultaneous presence of differential current and of overcurrent. • Easy to set tripping characteristic. Because the relay calculates its restraint current only the setpoint   Diff > and Diff>> must be set. • Differential and restraint current are monitored continously during normal operation and are displayed as operational measured values. • High stability during external faults even with different current transformers saturation level. For an external fault only 5 ms saturation free time are necessary to guarantee the reliability of the differential protection. • Single-phase short-circuits within the protection zone can be cleared using a time delay, whereas multi-phase faults are cleared instantaneously. Because of this function, the unit is optimally suited for applications in inductively compensated networks, where differential current can occur as a result of charge transfer phenomena on occurrence of a singlephase earth fault within the protection zone, thus resulting in undesired tripping by the differential protection relay. Undesired tripping of the differential protection can be suppressed by making use of the provision for introduction of a time delay on occurrence of single-phase faults. • With transformers or compensation coils in the protection zone, the sensitive response threshold  I Diff > can be blocked by an inrush detection function. Like in transformer differential protection, it works with the second harmonic of the measured current compared with the fundamental component. Blocking is cancelled from an adjustable threshold of the short-circuit current, so that very high current faults are switched off instantaneously.

The interference zero current, which flows through the earthed winding, is eliminated from the differential current. The 7SD610 thus behaves like a transformer differential relay whose ends, however, can lie quite far apart. Characteristics of differential protection communciation through the active interfaces The 7SD610is athome in communciation networks The data required for measurement of differential currents and numerous other variables are exchanged between the protection units in the form of synchronous serial telegrams employing the full duplex mode. The telegrams are secured using CRC check sums so that transmission errors in a communication network are detected immediately. Moreover, each telegram carries a time stamp accurate to a micro-second, thus allowing measurement and monitoring of the telegram transmission delay times. •  Data communication is immune to electromagnetic interference, since fiber-optic cables are employed in the critical region. •  Monitoring of each individual incoming telegram and of overall communication between the units, excluding supplementary equipment.

The check sum (correctness of the telegram contents), the address of the neighbor ing unit and the transmission delay time of the telegram are monitored. • Unambiguous identification of each unit is ensured by as signment of a settable communication address within a differential protection topology. Only those units mutually known to each other can cooperate. Incorrect interconnection of the communication links results in blocking of the protection system. • Detection of telegrams, which are reflected back to the transmitting unit within the communication network. • Detection of path switching in a communication network. Automatic restraint of the protection function until measurement of the parameters of the new communication link has been completed. • Continuous measurement of the transmission delay time to the remote line end. Taking into account of the delay time in differential current measurement and compensation thereof, including monitoring of a settable maximum permissible delay time of 30 ms. • Generation of alarm signals on disturbed communication links. Statistical values for the percentage availability of the communication links per minute and per hour are available as operational measured val ues.

Phase-selective intertrip and remote trip/indications Normally the differential current is calculated for each line end nearly at the same time. This leads to fast and uniform tripping times. Under weak infeed conditions, especially when the differential function is combined with an overcurrent pickup a phase selective intertrip offers a tripping of both line ends. • 7SD610 has 4 intertrip signals which are transmitted in high-speed (20 ms) to the other terminals. These intertrip signals can also be initiated and transmitted by an external relay via binary inputs. In cases where these signals are not employed for breaker intertripping, other alternative information can be rapidly transmitted to the remote end of the line. • In addition, four high-speed remote commands are available, which can be introduced either via a binary input or by means of an internal event and then rapidly communicated to the other end.  Provided that the circuit• breaker auxiliary contacts are wired to binary inputs at the line ends, the switching status of the circuit-breakers is indicated and evaluated at the remote ends of the line. Otherwise the switching status is derived from the measured current.

Possible modes of operation of the differential protection section • Special modes of operation such as the „Commissioning mode“ and „Test operation“ are advantageous for com missioning and servicing the units. • In general, an alarm indication is generated on interruption of the communication links and an attempt is made to re-establish the communication link. The units operate in the emergency or pickup mode, provided that these have been parameterized. • The complete configuration can also be used in a testing mode. The local end is in an operating mode, which, for example, allows testing of the pickup values. The current values received from the remote end of the line are set to zero, so as to achieve defined test conditions. The remote end unit ignores the differential currents, which occur as a result of testing, and blocks differential protection and breaker intertripping. It may optionally operate in the backup protection mode. • Differential protection is activated in the commissioning mode. However, test currents injected at one end of the line and which generate a differential current do not lead to output of a TRIP com mand by the differential protection or to breaker intertripping. All those indications that would actually occur in conjunction with a genuine short-circuit are generated and displayed. TRIP commands can be issued by the backup protection.

SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends Functions Thermal overload protection (ANSI 49) A built-in overload protection with a current and thermal alarm stage is provided for the thermal protection of cables and transformers. The trip time characteristics are exponential functions according to IEC 60255-8. The preload is considered in the trip times for overloads. An adjustable alarm stage can initiate an alarm before tripping is initiated. Overcurrent protection (ANSI 50, 50N, 51, 51N) The 7SD610 provides a threestage overcurrent protection. Two definite-time stages and one inverse-time stage (IDMT) are available, separately for phase currents and for the earth current. Two operating modes are selectable. The function can run in parallel to the differential protection or only for backup during interruption of the protection communication. Two stages e.g. can run in backup mode, whereas the third stage is configured for emergency operation. The available ANSI/IEC inverse-time curves are: • Inverse • Short inverse • Long inverse • Moderately inverse • Very inverse • Extremely inverse • Definite inverse Instantaneous high speed switch-onto-fault overcurrent protection (ANSI 50HS) Instantaneous tripping is possible when energizing a faulty line. On large fault currents, the high speed switch-onto-fault overcurrent stage can initiate very fast three-pole tripping. Circuit-breakter closure onto a faulty line is also possible provided that the circuit-breaker auxiliary contacts of the remote end are connected and monitored. If an overcurrent arises on closing of the circuit-breaker atone end ofa line (while the other end is energized) the measured current can only be due to a short-circuit. In this case, the energizing line end is tripped instantaneously.

  Siemens SIP5.4 ⋅ 2001

In the case of circuit-breaker closure the auto-reclosure is blocked at both ends of the line to prevent a further unsuccessful closure onto a short-circuit. If circuit-breaker intertripping to the remote end is activated, intertripping is also blocked. Auto-reclosure (ANSI 79) The 7SD610 relay is equipped with an auto-reclosure function (option). For 1-phase or for multiphase faults different dead times can be set. The function includes several operating modes:

• 3-pole auto-reclosure (AR) for all types of faults. • 1-pole auto-reclosure for 1-phase faults, no AR for multi-phase faults. • 1-pole AR for 1-phase faults and for 2-phase faults without earth, no AR for multiphase faults. • 1-pole AR for 1-phase and 3-pole AR for multi-phase faults. • 1-pole AR for 1-phase faults and 2-phase faults without earth and 3-pole AR for all other faults. • Multiple-shot AR. Up to 8 ARs are possible. • Interaction with an external protection relay for AR via binary inputs and binary outputs. • Adaptive autoclosure: Both breakers open after the fault in the protection zone has been detected. Only one relay switches on the breaker. If the fault has disappeared the other line end is switched on via communication links. If not, the line end makes a final trip. • Interrogation of synchrocheck protection before autoreclosure occurs. This issues the release signal for autoreclosure to the unit via a binary input. • Monitoring of the circuitbreaker auxiliary contacts and CB- ready status. • Voltage check for discrimination between successful and non-successful reclose attempts.

In addition to the above mentioned operating modes, several other operating modes can be performed and configured according to user-specific requirements by means of the integrated programmable logic (CFC). Breaker failure protection (ANSI 50BF) The 7SD610 relay incorporates a two-stage breaker failure protection to detect the failure of tripping command execution, for example due to a defective circuit-breaker. The current detection logic is phasesegregated and can therefore also be used in single-pole tripping schemes. If the fault current is not interrupted after a settable time delay has expired, a retrip command or a busbar trip command is generated. The breaker failure protection can be initiated by all integrated protection functions as well as by external devices via binary input signals. High-speed current monitoring and other monitoring functions Numerous monitoring functions for hardware and software are implemented in the 7SD610 unit. The measuring circuits, analog-to-digital conversion and the supply voltages,

memory and software execution (watch-dog function) are monitored. An open circuit between the CTs and relay inputs under load may lead to tripping of a differential relay if the load current exceeds the differential setpoint. The 7SD610 provides fast bus wire supervision which immediatelly blocks all line ends if an open circuit is measured by a local relay. This avoids maloperation due to open circuit. Only the phase where the open circuit is detected is blocked. The other phases remain under differential operation. Additional measurement supervision functions are: • Symmetry of voltages and currents • Summation of phase currents and comparison with the measured current at measuring input for the  I 4  earth current transformer. If a significant difference is detected, the differential protection is blocked immediately, because this difference can only originate in a hardware fault of the unit’s ana log part. • Phase-sequence supervision.

Trip circuit supervision (ANSI 74TC)

Measured values at remote line ends

One or two binary inputs for each circuit-breaker pole can be used for monitoring the circuit-breaker trip coils including the connecting cables. An alarm signal is issued whenever the circuit is interrupted. For each trip circuit 1 or 2 binary inputs can be used.

Every two seconds the currents and voltages are freezed at the same time and transmitted via the communication link. Therefore, currents and voltages at the two line ends are always available with their amount and phases . This allows checking the whole configuration under load conditions (load current of 10 % is sufficient). In addition, the differential and restraint currents are also displayed. Important communication link measurements, such asdelay time or as percentage availability per minute/hour are also available as measurements. These measured values can be processed with the help of the CFC logic editor.

Lockout (ANSI 86) All binary outputs can be stored like LEDs and reset using the LED reset key. The lockout state is also stored in the event of supply voltage failure. Reclosure can only be issued after the lockout state is reset. Local measured values The measured values are calculated from the measured current and voltage signals along with the power factor (cos ϕ), the frequency, the active and reactive power. Measured values are displayed as primary or secondary values. The relay uses a high-resolution AD converter and the analog inputs are factory calibrated, so a high accuracy is reached (under 0.5 % with rated current). The following values are available for measured value processing: • Currents 3 x   phase, 3 0, E • Voltages 3 x Vphase-earth, 3 x Vphase-phase, 3V0, Ven • Symmetrical components 1, 2, V 1, V22 (positive and negative phase-sequence system) • Active powerP (Watt), Reactive power Q (Var), Apparent power S (VA) • Power factor PF (= cos ϕ) • Frequency f • Differential and restraint current per phase Limit values are calculated by means of the CFC. User-specific indications can be derived from these limit value indications like overload conditions, overvoltage.

Commissioning and test functions Special attention has been paid to commissioning. All binary inputs and outputs can be displayed and set directly. This can simplify the wiring check significantly for the user. The measured values can be displayed via DIGSI 4 on the PC screen as primary, secondary and/or percentage values simultaneously. This provides a complete overview of the actual system conditions. The 7SD610 provides a circuitbreaker test function. Singleand three-pole TRIP commands can be issued and followed by a reclosing command. The pole open time can be set separately from the auto-reclosure dead time.

SIPROTEC 4 - 7SD610 Differential Protection Relay for Two Line Ends Control and automation functions Control

Switching priorities

In addition to the protection functions, the SIPROTEC 4 units also support all control and monitoring functions required for operating mediumvoltage or high-voltage substations. The principle task is reliable control and monitoring of switchgear and processes. The status of the circuit-breaker or disconnectors can be obtained via auxiliary contacts and transferred to the 7SD610 via binary inputs. Therefore it is possible to detect and indicate both the OPEN and CLOSE position or a faulty or intermediate position. The switchgear or circuit-breaker can be controlled via: − integrated operator panel −  binary inputs −  substation control system −  DIGSI 4.

The switching authority is selected by settings, DIGSI 4, binaryinputor - if available - by means of key-operated switches. The hierarchy of the switching authority is as follows: LOCAL, DIGSI 4, REMOTE. If the ”LOCAL” mode is selected, only local switching operations are possible. Every switching operation and change of breaker position is stored in the status indication memory. The switching command source, switching device, cause (i.e. spontaneous change or command) and result of a switching operation are recorded.

Command processing The 7SD610 supports all the tasks required for command processing, including the processing of single and double commands with or without feedback as well as monitoring of the control process. The control actions are monitored in terms of using functions such as runtime and subject to automatic command termination after feedback from the external process is provided to the 7SD610. Typical applications are: • Single and double commands and feed-back • User-definable bay interlocks • Operating sequences combining several switching operations such as control of circuit-breakers, disconnectors and earthing switches. • Derived triggering of switching operations, indications or alarms by logical combination of existing information.

Indication derivation A further indication (or a command) can be derived from an existing indication. Group indications can also be formed. The number of indications via the system interface can thus be reduced and restricted to the most important signals. Data transmission lockout

Filter time / filtering and delay of indications All binary indications can be subjected to a filter time (indication delay) to prevent spurious operation. Indications can be filtered or delayed. Filtering serves to suppress transient changes at the indication input. The indication is passed on only if the voltage is still present after a set periodof time. In the case of indication delay, there is a delay for a preset time. The information is passed on only if the voltage is still present after this time.

A data transmission lockout can be activated, so as to prevent transfer of information to the control center during work on the unit. Test mode During commissioning a test mode can be selected; all indications then have a test mode suffix for transmission to the control center.

Typical connection Connection to current and voltage transformers A typical connection is to the phase CT. The residual current at the  I E input is formed by summation of the phase currents. This ensures optimum supervision functions for the current. Optionally, voltages are measured by means of voltage transformers and are fed to the unit as a phase-to-earth voltage. The zero voltage is derived from the summation voltage by calculation performed in the unit. As a matter of fact, the 7SD610 unit does not require any voltages for operation as differential protection.
