7SA513 line protection relay (Version V3)
Fig. 1 7SA513 line protection relay
Application The 7SA513 numerical line protection relay provides selective and fast clearance of faults on overhead lines and cables with single and multiple end infeed in high voltage networks with any type of meshing. The neutral point can be earthed, compensated or isolated. The main function is a fast 6-system distance protection with a polygon fault detection and tripping characteristic. A fault detection program with a V/ I/ characteristic is also available instead of the polygon fault detection characteristic. The unit also incorporates all functions usually required for line protection. It can also be used as backup overcurrent and distance protection for all types of differential protection equipment. The unit can be integrated both into conventional installations and into SINAUT LSA 678 substation control and protection.
Design The compact 7SA513 line protection relay contains all the components required for analog value acquisition and evaluation, the operating and display panel, indication and command outputs, binary input options, serial interfaces and auxiliary voltage converters. The use of a powerful 32-bit signal processor combined with a 16-bit standard processor permits integration of numerous protection functions into a compact device. Three housing versions can be supplied. The version for surface-mounting on a switchboard is fitted with double-tier terminals accessible from the front. The versions for flush-mounting in a switchboard or cubicle have connecting elements at the rear and are available with or without a glass cover. Method of operation All data processing within the 7SA513 line protection relay is digital, from the measurement and digitization of voltages and currents to the tripping decision logic. Computer-bound, digital measuring methods largely suppress the influence of inrush currents, transient DC components, higher frequency transients and harmonics. In the distance protection function measuring errors due to load currents and currents on the parallel line can be compensated.
Serial interfaces The unit is equipped with 2 serial interfaces. The operating interface on the front is suitable for connecting PCs. The DIGSI operating program running under WINDOWS, provides user-friendly settings, evaluation of fault recordings and faults, and commissioning. The system interface is available as a fibre optics interface for connection to the SINAUT LSA 678 substation control and protection or a relay data concentrator. The communication protocol used conforms to the recommendations of VDEW/ ZVEI based on IEC 8705103. The Siemens-specific protocol conforming to DIN 19 244 is still available for existing installations. Setting All parameters can be set by the operator using the integrated keypad and display panel or a PC. The parameters are stored in non-volatile memory so that they are retained even after the supply voltage has been switched off. Self-monitoring The hardware and software components are constantly monitored and any irregularities are immediately detected and signalled. This ensures a high degree of safety, reliability and availability.

Distance protection The main function of the 7SA513 line protection relay is a six-system distance protection. By parallel calculation and monitoring of all six impedance loops a high degree of sensitivity and selectivity is achieved for all types of fault. The shortest command time is less than one network cycle. The fault detection characteristic used is the polygon impedance fault detection Z< (see Fig. 2). The shape of the fault detection polygon permits optimum adaptation to the load conditions on the protected line. Starting of unfaulted loops is eliminated to prevent the adverse influence of currents and voltages in the fault free loops. Overcurrent fault detection can be activated in parallel to the polygon impedance fault detection. As an option to the polygon impedance fault detection, voltage and angle-dependent overcurrent fault detection may also be used (see Fig. 3). This V/ I/ characteristic uses the phase voltages VphE or the line voltages Vphph depending on the phase angle and the phase current Iph according to the selected mode of starting. The polygon tripping characteristic permits separate setting of the reactance X and the resistance R (see Fig. 4). The reactance section R can be set separately for faults with and without earth involvement. Earth faults are detected by monitoring the earth current IE, the negative phase sequence current I2 and/or the displacement voltage VE. Five distance zones can be set forward, reverse or non-directionally, two of them as overreach zones for automatic reclosure and permissible tripping schemes. For each distance zone a time stage is available for the directional and non-directional characteristic (A total of 10 independent time stages). Compensation for load current and parallel lines is included. Digital filtering of the measured values makes the unit insensitive to disturbances in the measured quantities. In particular the influence of DC components, capacitive voltage transformers, series compensated lines and frequency changes are reduced. Sound phase polarization and voltage memories provides dynamically unlimited directional sensitivity. Phase selective 1-pole or 3-pole tripping is possible when used with 1-pole or 1 and 3-pole rapid or delayed auto reclosing scheme.

Fig. 4 Tripping characteristics of the distance protection
Distance protection (continued) Following the loss of V.T. voltage inputs, the distance protection can be blocked automatically to prevent incorrect operation. The distance protection has an instantaneous tripping level I>>>. If this level is exceeded tripping is immediate. This level can be used on very long lines if a large short-circuit current is expected from close in faults while the short-circuit current for reverse faults will definitely be reduced to a level below the setting value. The function can be deactivated (default setting). Fault location The fault location function calculates the fault impedance and the distance-to-fault. The result can be displayed in ohms, kilometers or percent of the line length. Parallel line and load current compensation is also available for fault location function. Signal transmission For fast selective clearance of faults up to 100 % of the line length a signal transmission function is available. The following modes may be selected: D Permissible underreach transfer trip with fault detection D Zone acceleration with Z1B D Permissible overreach with overreach zone Z1B D Direction comparison with directional fault detection D Unblocking mode with overreach zone Z1B D Unblocking mode with directional fault detection D Blocking mode D Overreach zone comparison via pilot wires D Reverse interlocking. The transient blocking function is provided with overreaching schemes to transient or current reversals resulting from the clearance of short circuits on parallel lines.

Network power swing

Fig. 5 Polygon for power swing detection
Network power swings During network power swings large currents can occur alone with small voltages. Small voltages and large currents imply small impedances which can cause distance protection tripping. To avoid uncontrolled tripping by the distance protection and to achieve controlled tripping in the event of loss of synchronism (pole slip), a power swing supplement is available for the 7SA513 line protection relay. The following operating modes for network power swings can be set: D Power swing blocking to prevent the distance protection from tripping D Power swing tripping for controlled tripping in the event of unstable power swings (out-of-step protection). Weak infeed protection To prevent delayed tripping of permissible schemes during weak or zero infeed situations, an echo function is provided. If no fault detector picks up at one end of the line, the signal received here is returned as echo to allow accelerated tripping at the other end of the line. It is also possible to initiate tripping during a weak infeed. At the end of the line where the fault detector does not pick up, a phase selective 1-pole or 3-pole trip is issued if a corresponding drop in the PhE voltage is present.
Overcurrent protection as a backup function and emergency function during measured voltage failure The 7SA513 line protection relay includes overcurrent protection. It can be used as a backup function and as an emergency function in the event of a short-circuit or interruption in the voltage transformer circuit or if the circuit-breaker of the voltage transformer trips. The settings for the emergency function may differ from those of the backup protection function. The overcurrent protection can be set as two-stage definite-time overcurrent protection or as inverse-time overcurrent protection.
Switch-on-to-fault protection Instantaneous tripping is possible when energizing a short-circuited line. Initiation of the binary input Manual Close will, depending on the setting, result in instantaneous tripping in Z1, Z1B or fault detection. On definite, large current faults the high current instantaneous stage can initiate very fast 3-pole tripping even if the binary input Manual Close is not initiated.
Automatic reclosure The 7SA513 relay is equipped with automatic reclosure (ARC). The range of functions includes: D 3-pole RAR/DAR1) for all types of faults D 1-pole RAR for 1-phase faults, no reclose for polyphase faults D 1-pole RAR for 1-phase and 2-phase faults without earth, no reclose for poly-phase faults D 1-pole RAR for 1-phase and 3-pole RAR/DAR for poly-phase faults D 1-pole RAR for 1-phase and 2-phase faults without earth and 3-pole RAR/ DAR for other faults D Multiple-shot DAR D Interaction with an external device for automatic reclosure via binary inputs and outputs D Control of the integrated ARC function by external protection D ARC blocking for faults on the cable portion of mixed cable/overhead lines D Interaction with an internal or external synchro check D Monitoring of the circuit-breaker auxiliary contacts. High resistance earthfault protection in an earthed network In earthed networks where high resistance earth faults can occur, the fault detection of the distance protection may not be sensitive enough. The 7SA513 line protection relay has protection functions for high-resistance earth faults of this nature. Only one of these functions can be active at any one time: D Directional or non-directional earth fault protection with definite-time overcurrent characteristic D Directional or non-directional earth fault protection with inverse-time overcurrent characteristic D Directional or non-directional earth fault protection with voltage-dependent characteristic (V0 inverse characteristic). To implement a directional comparison scheme, the directional earth-fault function can be supplemented with a signal transmission logic. Earth-fault direction detection is performed with residual current and residual voltage. In addition or as an alternative to the residual voltage, the start point current (IY) of an earthed transformer may be used for polarization of the directional earth-fault function. A phase selector permits single pole tripping by the earth-fault protection in the event of single phase earth-faults in conjunction with uni-polar automatic reclosing. Synchronism check When connecting two network sections by control command or following a 3-pole auto-reclosure, it must be ensured that the two network sections are in synchronism. For this purpose a synchronism check function is provided. After verification of network synchronism, the function enables the CLOSE command. Alternatively reclosure can be enabled after a checking that the busbar or line is not carrying a voltage (dead line or dead bus). Overvoltage protection On very long EHV lines that carry no or light load impermissible overvoltages can occur due to the Ferranti effect. For protection against these overvoltages the 7SA513 line protection relay contains a two stage overvoltage protection. Compounding can be set for the V> stage that calculates the voltages at the remote end of the line. Tripping can be performed at the local circuit-breaker or at the remote end of the line by transmission of an intertripping signal. Circuit-breaker failure protection The 7SA513 line protection incorporates a single stage circuit-breaker failure protection function to detect failure of trip commands, for example due to a defective circuit-breaker. The current detection logic is phase selective and can therefore also be used in single pole tripping schemes. If the fault current has not been interrupted after a set time delay has elapsed, the busbar trip command is generated. Parameter set switchover It is possible to switch between four different parameter sets via the binary inputs, the integrated operating panel or the serial operating interface. In this way it is possible to adapt the protection relay settings if the network configuration has been changed by switching actions. Parameter set switchover is also possible via the compatible VDEW/ZVEI interface protocol. Fault value recording The digitized measured values of the phase currents, earth currents, phase voltages as well as displacement voltage and several binary channels are stored with a set pre- and post fault time. The fault value recording can be transferred to a PC and the SINAUT LSA 678 substation control and protection for evaluation. Parallel use of a PC and the substation control and protection is possible. If the VDEW/ZVEI interface is used, up to 8 fault value recordings can be stored. The data memory is a ring buffer with a maximum length of 10 s (at fN = 50 Hz). The oldest fault value recording is overwritten by the latest data. Fault value recording can be started via a binary input or, as an aid to commissioning, via the integrated operator panel or PC. The recording duration can then be parameterized. The fault value recording memory is protected against failure of the supply voltage. Marshalled command and alarm relays, LEDs, binary inputs The device is equipped with several command relays with trip duty contacts. They can be assigned both to the commands of the integrated protection functions as well as to all other alarm outputs or binary signals. Alarm relays and LEDs can be freely assigned for user-specific output and display of alarms and events. Several single indications can be grouped together to form a group indication. The retentive LED displays are protected against failure of the supply voltage. All binary inputs can also be freely marshalled. Measuring and test functions Numerous measuring and test functions are integrated in the 7SA513 line protection for commissioning and operational measurement: D Measurement of the in-service impedance of all 6 loops and display of direction, reactance and resistance D Monitoring of the phase sequence D In-service measurement Iph1, Iph2, Iph3 D In-service measurement Vph1-ph2, Vph2-ph3, Vph3-ph1, Vph1, Vph2, Vph3 D Active and reactive power measurement (W and VAR) D Frequency measurement D Trip circuit test with circuit-breaker, 1 and 3-pole D Test ARC, 1 and 3-pole.

Non-volatile storage of operational records The 7SA513 unit provides detailed data for the analysis of faults and for checking states during operation. All the event memories listed below are backed up against failure of the supply voltage. D Time As a standard a battery backed up clock is available which can be synchronized via a binary input. The clock can be set via the PC and VDEW/ZVEI interface. The time and date are assigned to all events. D Fault records The events of the last 3 network faults can be retrieved at any time via the integrated operator panels. The events of the last 8 network faults are available via the PC interface. D Operational events All events that are not immediately associated by the fault are stored in the operational event memory. D Tripping statistics For each pole of the circuit-breaker the trip and close cycles as well as the disconnected current are summated separately. D Automatic display on the LCD An operating mode can be activated in which up to 2 operational measured values are display in the integrated LCD. When a fault occurs the display automatically indicates 2 selected items of fault information. User-definable binary inputs and time delays, external trip signals To register binary signals that could for instance be generated by other protection devices, 4 binary inputs are provided. They are stored in the operational event buffer and can be signalled via alarm relays, LEDs and SINAUT LSA substation control. The unit is also equipped with 2 settable time stages. The start and reset signals can be marshalled to binary inputs, the time stage output to alarm relays and LEDs. A wide range of pick-up and dropoff times can be set. In future the use of external time relays for special applications will no longer be necessary. Phase selective remote tripping with and without automatic reclosure can be achieved by coupling external signals via binary input.
