SIPROTEC 4 7SJ61/62/63 / 6MD63 M ultifunction Protection Relay and Bay Controller Description Application

Line protection

The SIPROTEC 4 units are numerical relays that also perform control and monitoring functions and therefore support the user in costeffective power system management, and ensure reliable supply of electric pow er to the customers. Local operation has been designed according to ergonomic criteria. Large, easy-to-read displays w ere a major design aim. The SIPROTEC 4 units have a uniform design and a degree of functionality w hich represents a whole new quality in protection and control. The use of a pow erful microcontroller and the application of digital measured value conditioning and processing largely suppresses the influence of higher-frequency transient phenomena and DC components. The protective functions evaluate t he fundamental wave. The overload protection evaluates r.m.s. values.

The SIPROTEC 4 units can be used for line protection of high and medium voltage networks w ith grounded (earthed), lowresistance grounded, isolated or compensated neutral point.

Programmable logic

The integrated logic characteristics allow the user to implement his own functions for automation of sw itchgear (interlocking) or a substation via a graphic user interface. The user can also generate user-defined messages. Communication

The SIPROTEC 4 units possess up to t hree serial interfaces: − Front int erface for connecting a PC − System interface for connecting to a control system via IEC 60870-5-103 or Profibus-FMS/DP, Modbus RTU, DNP 3.0 − Data t ransmission − Time synchronization via binary input IRIG B/SCADA (DCF 77) − Prepared for UCA, Ethernet

Motor protection

For motor protection, the SIPROTEC 4 units are suitable for asynchronous machines of all sizes. Transformer protection

The SIPROTEC 4 units perform all functions of back-up protection supplementary to t ransformer differential protection. The inrush suppression effectively prevents tripping by inrush currents. Back-up protection

The SIPROTEC 4 units can be used universally for back-up protection. Control

The integrated control function permits control of disconnect devices (electrically operated/motorized swit ches) or circuitbreakers via the integrated operator panel, binary inputs, DIGSI 4 or the control and protection system (e.g. SICAM). They support substations wit h single and duplicate busbars. The number of elements t hat can be controlled (usually 1 to 5) is only restricted by the number of input s and outputs available. A full range of command processing functions are provided. Application matrix

Protection functions

The SIPROTEC 4 units are available with a variety of protective funct ions. Pre defined application packages can be implemented to make selection easier for the user. Metering values

Extensive measured values, limit values and metered values permit improved system management, as w ell as simplified commissioning. Transducer

Uses two 4 to 20 mA input interfaces. Operational indications Indications with t ime stamp

The SIPROTEC 4 units provide extensive data for fault analysis, as well as control. All indications listed below are protected against power supply failure. Fault signals The last eight fault cases and 3 sensitive ground f ault cases are always stored in the unit. All fault recordings are time stamped wit h a resolution of 1 msec.

Operational indications All indications that are not directly associated with the fault (e.g. operating or switching actions) are stored in the status indication buffer. The time resolution is 1 ms, buffer size: 80 indications. Fault recording up to 5 seconds

The digitized values for phase currents, ground (earth) currents, line and zero-sequence current s are recorded in a fault recording. The record can be started using a binary input, on initiation or w hen a trip command output occurs. Up to eight fault recordings may be stored. For test purposes, it is possible to start a fault recording via DIGSI 4 or the connected control and protection system.

Time synchronization

Continuous self-monitoring

A battery-backed clock is a standard component and can be synchronized via a synchronization signal (DCF77, IRIG B via satellite receiver), binary input, system int erface or SCADA (e.g. SICAM ). A date and time is assigned to every indication.

The hardware and software are continuously monitored. If abnormal conditions are detected, the units signals immediately. In this w ay, a great degree of safety, reliability and availability is achieved. Reliable battery monitoring

Selectable binary inputs and outputs

Binary inputs, outputs and LEDs can be assigned to perform specific functions as defined by the user. Selectable function keys

Four function keys can be assigned to permit the user to perform f requently recurring actions very quickly and simply. Typical applications are, for example, jumps to a given position in the menu tree in order to display the list of operating indications or to perform automatic functions, such as “ Switching of circuit-breaker” .

The battery that is provided is used to back-up the clock, switching statistics, the status and fault indications and the fault recording in the event of a power supply failure. Its funct ion is checked by the processor at regular intervals. If the capacity of the battery is found to be declining, an alarm is generated. Regular replacement is therefore not necessary. All setting parameters are stored in t he Flash-EPROM which are not lost if t he power supply or battery fails. The SIPROTEC 4 unit remains fully f unctional.

SIPROTEC 4 7SJ61/62/63 / 6MD63 M ultifunction Protection Relay and Bay Controller SIPROTEC 4/ SICAM system/ SCADA SIPROTEC 4 as integral part of SICAM energy automation system

SIPROTEC 4 is tailor-made for use in the SIMATIC-based SICAM energy automation system. The SICAM family consists of the following components: SICAM RTU, the modern telecontrol system with automation and PLC functions SICAM SAS, the m odern integration of switchgear automation and information technology SICAM PCC, the information and communication technology on a PC basis Softw are data management and communication is one of t he strong-points of combining of SICAM and SIPROTEC 4. Powerful engineering tools (SICAM plus TOOLS on the basis of STEP7 and SICAM WinCC) make working w ith SICAM convenient. The SIPROTEC 4 units are optimally matched for use in SICAM SAS and SICAM PCC. Wit h SICAM and SIPROTEC 4 continuit y exists at three central points: Data management Software architecture Communication. All central system components (SICAM and SIPROTEC 4 CPUs, SICAM WinCC, SICAM plus TOOLS, bay controllers and protection equipment), as well as the DIGSI 4 operating program, are established on the same basis. The interface and ability to link SICAM/  SIPROTEC and other components of the substation control, protection and automation is assured via open interfaces, such as IEC 60870-5-103 or PROFIBUS. Service bus

DIGSI 4 offers the additional possibility of accessing bay controllers via modem. It is possible to read out from t he office desk or when travelling (by laptop and modem) the operational and fault event logs, fault records, as well as operational measured values of all protection devices of an installation. This permits rapid and extensive access for the service personnel. Star coupler

All SIPROTEC units operate also with the proven star coupler. The star coupler is used for sim ple applications which also give the user an alternate method of retrieving information remotely.

SIPROTEC 4 7SJ61/62/63 / 6MD63 M ultifunction Protection Relay and Bay Controller Communication

With respect to communication, particular emphasis is placed on the requirements customary in energy automation: Every data item is timestamped at the source, i.e. where it originates. The communication system automatically handles the transfer of large data blocks (e.g. fault recordings or parameter data files). The user can apply these features without any additional programming effort. For the reliable execution of a command, the relevant signal is first acknowledged in the unit involved. When the command has been enabled and executed, a check-back indication is issued. The actual conditions are checked at every command handling step. Whenever they are not satisfied, controlled interruption is possible.

It is generally impossible to communicate with a unit that has failed. If a unit were to fail, there is no effect on the communication wit h the rest of the system.

Commands can be derived from t his limit value indication. Zero suppression In a certain range of very low m easured values, the value is set to zero to suppress interference.

For internal met ering, the unit can calculate an energy metered value from the measured current and voltage values. If an external meter with a metering pulse output is available, the SIPROTEC 4 unit can obtain and process metering pulses via an indication input. The metered values can be displayed and passed on to a control center as an accumulation with reset. A distinction is made betw een forw ard, reverse, active and reactive energy. Measuring transducers

Characteristic with knee For measuring transducers it sometimes makes sense to extend a small range of the input value, e.g. for the frequency that is only relevant in the range 45 to 55, 55 to 65 Hz. This can be achieved by using a knee characteristic. Live-zero monitoring 4 - 20 mA circuits are monitored for open-circuit detection.

SIPROTEC 4 7SJ61/62/63 / 6MD63 M ultifunction Protection Relay and Bay Controller Functions Control and automatic functions Control

In addition to the protection funct ions, t he SIPRORTEC 4 units also support all control and monitoring functions t hat are required for operating medium-voltage or highvoltage substations. The main application is reliable control of swit ching and other processes. The status of primary equipment or auxiliary devices can be obtained from auxiliary contacts and communicated to the 7SJ62/63 via binary inputs. Therefore it is possible to detect and indicate both the OPEN and CLOSED position or a fault or intermediate circuit-breaker or auxiliary contact position. The switchgear or circuitbreaker can be controlled via: − integrated operator panel − binary inputs − substation control and protection system − DIGSI 4 Automation

With integrated logic, the user can set, via a graphic interface (CFC), specific functions for the automation of swit chgear or substation. Functions are activated via function keys, binary input or via communication interf ace. Swit ching authority

Switching authority is determined according to parameters, comm unication or by key-operated sw itch (when available). If a source is set to “ LOCAL” , only local switching operations are possible. The following sequence of swit ching authority is laid dow n: “ LOCAL” ; DIGSI PC program, “ REM OTE” Every sw itching operation and change of breaker position is kept in t he status indication memory. The swit ch command source, swit ching device, cause (i.e. spontaneous change or command) and result of a switching operation are retained.

This includes the processing of single and double commands wit h or wit hout feedback, sophisticated m onitoring of t he control hardware and softw are, checking of the external process, control actions using functions such as runtime m onitoring and automatic command term ination after out put. Here are some typical applications: Single and double commands using 1, 1 plus 1 common or 2 trip contacts User-definable bay int erlocks Operating sequences combining several switching operations such as control of circuit-breakers, disconnectors and earthing switches Triggering of switching operations, indications or alarm by combination with existing information

Assignment of feedback to command

Indication filtering and delay

The positions of t he circuitbreaker or sw itching devices and transformer taps are acquired by feedback. These indication inputs are logically assigned to the corresponding command output s. The unit can therefore distinguish whether the indication change is a consequence of swit ching operation or whether it is a spontaneous change of state (intermediate position).

Indications can be filtered or delayed. Filtering serves to suppress brief changes in potential at the indication input. The indication is passed on only if the indication voltage is still present after a set period of time. In the event of indication delay, there is a wait for a preset tim e. The information is passed on only if the indication voltage is still present after this time.

Chatter disable

Indication derivation

Chatter disable feature evaluates whet her, in a configured period of time, the number of status changes of indication input exceeds a specified figure. If exceeded, the indication input is blocked for a certain period, so that the event list w ill not record excessive operations. Filter time

All binary indications can be subjected to a filter time (indication suppression)

A further indication (or a command) can be derived from an existing indication. Group indications can also be formed. The volume of information to the system interface can thus be reduced and restricted to the most important signals.

Transmission lockout

A data transmission lockout can be activated, so as to prevent transfer of information to the control center during w ork on a circuit bay. Test operation

During comm issioning, all indications can be passed to a automatic control system for test purposes.

Motor control

For direct activation of the circuit-breaker, disconnector and grounding switch operating mechanisms in automated substations, the SIPROTEC 4 units 7SJ63/6MD63 with highperformance relays are available. Interlocking of t he individual swit ching devices takes place with the aid of programmable logic. Additional auxiliary relays can be eliminated. This results in less w iring and engineering effort.

This function is based on the phase-selective measurement of the three phase currents and the ground current (four transformers). Two definite-time overcurrent protection elements (DM T) exist both for the phases and for the ground. The current threshold and the delay time can be set in a wide range. As an option, inverse-time overcurrent protection characterist ics (IDMTL) can be activated:

For directional and nondirectional time-overcurrent protection functions the initiation thresholds and tripping times can be switched via binary inputs or by t ime control. See page 25.

Directional tim eovercurrent protection (ANSI 67, 67N)

Phase and ground directionality is performed independently in the 7SJ62/7SJ63. The phase and ground function parallel the non-directional overcurrent element. Their response value and delay times can be set separately. As an option, inverse directional timeovercurrent protection characteristics (IDMTL) can be connected. The tripping characteristic can be rotated about ±45 degrees.

The directional overcurrenttime protection maintains a voltage memory of 2 cycles prior to the f ault. By means of voltage memory, directionality can be determined reliably even for close in (local) faults. If the swit ching device closes onto a fault and the voltage is too low to determine direction, directionality (directional decision) is made w ith voltage from voltage memory. If no voltage exists in m emory, tripping occurs according to the coordination schedule.

Sensitive directional ground-fault detection (ANSI 64, 67Ns)

For isolated-neutral and compensated netw orks, the direction of power flow in the zero sequence is calculated from the zero-sequence current I 0 and zero-sequence voltage V 0. For netw orks w ith an isolated neutral, the reactive current component is evaluated; for compensated networks the active current component or residual resistive current is evaluated. For special network conditions, e.g. highresistance grounded networks with ohmic-capacitive ground fault current or low resistance grounded networks with ohmic-inductive current, the tripping

characteristics can be rotated approximately ±45 degrees (see Fig. 45). Two modes of ground fault direction detection can be implemented: tripping or in “ signaling only mode” .

It is used for selective protection of sections fed from two sources with instantaneous tripping, i.e. without the disadvantage of time coordination. The directional comparison protection is suitable if the distances between the protection stations are not significant and pilot wires are available for signal transmission. In addition to the directional comparison protection, t he directional coordinated time-overcurrent protection is used for complete selective back-up protection. If operated in a closed-circuit connection, an interruption of the transmission line is detected. Fig. 47

Directional comparison protection

Breaker failure protection (ANSI 50BF)

If a faulted portion of the electrical circuit is not disconnected upon issuance of a trip comm and, another command can be initiated using the breaker failure protection w hich operates the circuitbreaker, say, of an upstream (higher-level) protection relay. Breaker failure is detected if aft er a trip command, current is still flow ing in the f aulted circuit. As an option it is possible to make use of the circuit-breaker position indication. Phase balance current protection (Negative sequence protection) (ANSI 46)

In line protection, the twoelement phase balance current/negative sequence protection permits detection on the high side high-resistance phase-to-phase faults and phase-to-ground faults that are on the low side of a transformer (e.g., with the switch group Dy 5). This provides back-up protection for high-resistance faults beyond the t ransformer. To detect the unbalanced load, the ratio negative-sequence current /  nominal current is evaluated.

20 Siemens SIP 3.1 ⋅ 1999

Auto-reclose (ANSI 79)

M ultiple recloses can be defined by the user and lockout will occur if a fault is present after the last reclose. The following functions are possible: 3-phase ARC for all types of fault Separate settings for phase and ground faults Multiple ARC, one rapid auto-reclose (RAR) and up to nine delayed autorecloses (DAR) Starting of the ARC depends on the trip command selection (e.g. 46, 50, 51, 67). Blocking option of the ARC via binary inputs ARC can be initiated externally Blocking of the directional and non-directional high-set elements.

Thermal overload protection (ANSI 49)

For protecting cables and transformers, an overload protection with an integrated prewarning element for temperature and current can be applied. The temperature is calculated using a thermal homogeneous-body model (according t o IEC 60255-8), w hich takes account both of the energy entering the equipment and the energy losses. The calculated temperature is constantly ad justed accordingly. This takes account of the previous load and the load fluct uations. For thermal protection of m otors (especially the stator) a further time constant τ can be set so that the thermal ratios can be detected correctly while the motor is rotating and when it is stopped. The model automatically functions correctly, if the equipment is operated within the limits of the ambient temperature for w hich the maximum load current is rated by the manufacturer. If the ambient tem perature fluctuates (e.g. summer/w inter), correction is possible via a second parameter set. The tripping time t  is calculated for a current step w ith static current values acc. to the following form: Overload protection w ithout preload detection 2

Start inhibit (ANSI 66/ 86)

If a motor is started up too m any times in succession, the rotor can be subject to thermal overload, especially the upper edges of the bars. The rotor temperature is calculated from the stator current and the temperature characteristic is shown in a schematic diagram. The reclosing lockout only permit s startup of the motor if the rotor has sufficient t hermal reserves for a complete startup, see Fig. 50. Emergency startup

This function disables the reclosing lockout via a binary input by st oring the state of the thermal image until the binary input is active. It is also possible to reset the t hermal replica to zero.

Undercurrent monitoring (ANSI 37)

With this funct ion, a sudden drop in current is detected that can occur due to a reduced motor load. This can cause shaft breakage, no-load operation of pumps or fan failure. Voltage protection Overvoltage protection (ANSI 59)

The overvoltage protection detects unwanted network and machine overvoltage conditions. Undervoltage protection (ANSI 27)

The two-element undervoltage protection provides protection against dangerous voltage drops (especially for electric machines). Applications include the isolation of generators or mot ors from the netw ork to avoid undesired operating states and a possible loss of stability. Proper operating conditions of electrical machines are best evaluated w ith the positive sequence quantities. The protection function is active over a wide frequency range (45 to 55, 55 to 65 Hz). The undervoltage protection is supervised by a binary input using the CB position to block protection trips prior to placing equipment on-line. Regionalization

The SIPROTEC 4 units 7SJ61/62 can be supplied in regional versions. The user purchases only the functions required. The available functions are matched to the technical requirements of t he regions. See table at right.

1) The 45 to 55, 55 to 65 Hz range is available for f N= 50/60 Hz

Frequency protection (ANSI 81O/U )

Frequency protection can be used for overfrequency and underfrequency protection. Electric machines and parts of the system are protected from unwanted speed deviations. Unwanted frequency changes in the netw ork can be detected and the load can be removed at a specified frequency sett ing. Frequency protection can be used over a wide frequency range (45 to 55, 55 to 65 Hz). Four elements (selectable as overfrequency or underfrequency) and each element can be delayed separately. Blocking of the f requency protection can be performed if using a binary input or by using an undervoltage element. Customized functions ANSI 32, 51V, 55, etc.

Additional functions, which are not time critical, can be implemented via the CFC using measured values. Typical functions include reserve power, volt age controlled overcurrent, phase angle detection, and zero sequence voltage detection.

Inrush restraint

The relay features second harmonic restraint. If the second harmonic is detected during transformer energization, triggering of trip non-directional and directional elements are blocked. Commissioning

Commissioning could hardly be easier and is fully supported by DIGSI 4. The status of the binary inputs can be read individually and the state of t he binary outputs can be set individually. The operation of sw itching elements (CBs, disconnect devices) can be checked using the switching functions of the bay controller. The analog measured values are represented as wide-ranging operational measured values. To prevent transmission of information to the control center during maintenance, the bay controller communications can be disabled to prevent unnecessary data from being transmitted. During commissioning, all indications with test marking for test purposes can be connected to a control and protection system.

Typical applications Line feeder w ith load shedding

In unstable netw orks (e.g. solitary networks, emergency power supply in hospitals), it may be necessary to isolate selected loads from t he network to prevent overload of the overall netw ork. The overcurrent time protection functions are effective only in the case of a short circuit. Overloading of the generator can be measured as a frequency or voltage drop.

Fig. 60

Line feeder w ith load shedding

Dynamic setting for coldload starts

The initiation thresholds and the tripping tim es can be changed for directional and non-directional time overcurrent protection functions via binary input or time control. Example: Cold load pickup after a ten-minute power failure. After long outage periods, there is an increased demand for energy for a limit ed period due to cooling or heating systems. The less sensitive settings are activated wit h the aid of a timer (CB OPEN time). When a second timer (ACTIVE time) finishes its run, the original settings are reactivated. A third tim er (STOP time) supervises the process, starting as soon as the current level falls below t he original setting. If t he current stays below that level while the second timer is running, the original setting is reactivated after the third timer finishes ist run. This gives more reliability on protection, since the original settings are reactivated faster. Fig. 61

26 Siemens SIP 3.1 ⋅ 1999

The auto-reclose features provide starting and blocking functions as described on page 20. Figure 63 gives an example w here the blocking of the reclosing function is applied. Time current coordination is implemented with the tim e-overcurrent sett ings of t he bay controller. If a fault occurs, the f eeder is tripped with an instantaneous element and automatically reclosed. With the circuitbreaker operating instantaneously, no other protection devices will operate (fuse saving scheme). If the fault still exists after t he breaker is automatically reclosed, additional reclosing attempts can be made. (A high-set instantaneous element of the upstream breaker can be set so it w ill not operate for a fault beyond the downstream protection device.) Low-set instantaneous elements of t he upstream breaker will be blocked during subsequent faults on the feeder; however, the downstream breaker can be set to provide an additional instantaneous trip or be time-delayed to allow downstream fuses to operate. If suff icient time delay is provided, a downst ream fuse can operate and no further breaker operations are required. Time coordination of the breakers will limit the outage to a smaller portion of the feeder if the fault is downstream of the second breaker. If additional reclosing equipment is installed on the same feeder,

reclosing schemes can be altered to limit protection to smaller portions of the feeder (zone sequencing). Relay settings are assigned and allow the furthest downstream breaker to operate f irst. This makes it possible to reduce the number of reclosing attempts on the feeder. Busbar protection (reverse interlocking)

By using binary inputs (closed-circuit or open-circuit current) it is possible to block the high current tripping of individual protection relays. In this w ay, it is possible to implement a simple bus protection (reverse interlock scheme).

Fig. 64

Bus protection (reverse interlocking)

Transformer protection

The high-set element permits current coordination w here the overcurrent element f unctions as a back-up for the lower-level protection relays, and the overload function protects the t ransformer f rom thermal overload. Low-current single-phase faults on the low voltage side that map into the negative-sequence system on the high-voltage side can be detected with the negative sequence protection. The available inrush restraint prevents tripping due to inrush currents of the transformer.

Via a binary input, it is possible to detect a locked rotor and isolate im mediately. The reclosing lockout can be deactivated for “ emergency startup” . The undervoltage function prevents startup on insufficient voltage and the overvoltage function prevents insulation damage.

In this case the sensitive transformer must also be looped into the ground current circuit.

Connection of circuitbreaker Undervoltage releases

Undervoltage releases are used for automatic tripping of high-voltage motors. Example: DC supply voltage of control system fails and manual electric t ripping is no longer possible. Automatic tripping takes place when voltage across the coil drops below the trip limit. In Fig. 74, tripping occurs due to failure of DC supply voltage, by automatic opening of the live status contact upon failure of protection unit or by shortcircuiting the t rip coil in event of netw ork fault.

In Fig. 75, tripping is by failure of auxiliary voltage and by interruption of t ripping circuit in event of network failure. Upon failure of protection unit, t ripping circuit is also interrupted, since contact held by internal logic drops back into open position. Motor control (see page 13). Trip circuit supervision (ANSI 74TC)

One or tw o binary inputs can be used for monitoring the circuit-breaker trip coil including its incoming cables. An alarm signal occurs whenever the circuit is interrupted. Fig. 75
