Page 23: Overall Operation
1 Introduction Overall Operation The SIPROTEC 7SJ62/63/64 are numerical, multi-functional, protective and control devices equipped with a powerful microprocessor. All tasks are processed digitally ex- clusively, from acquisition of measured values up to commands to the circuit breakers. Figure 1-1 illustrates the basic structure of the devices 7SJ62/63, Figure 1-2 illustrates the basic structure of the device 7SJ64.
Page 24 1.1 Overall Operation Voltage inputs can either be used to measure the three phase-to-ground voltages, or two phase-to-phase voltages and the displacement voltage (V voltage). It is also pos- sible to connect two phase-to-phase voltages in open-delta connection. The four voltage transformers of 7SJ64 can either be applied for the input of 3 phase- to-ground voltages, one displacement voltage (V voltage) or a further voltage for the synchronizing function.

Page 26 1.1 Overall Operation Power Supply The before-mentioned function elements and their voltage levels are supplied with power by a power supplying unit (Vaux or PS). Voltage dips may occur if the voltage supply system (substation battery) becomes short-circuited. Usually, they are bridged by a capacitor (see also Technical Data).
Page 27: Application Scope
1 Introduction Application Scope The numerical, multi-functional SIPROTEC 4 7SJ62/63/64 are versatile devices de- signed for protection, control and monitoring of busbar feeders. The devices can be used for line protection in networks that are grounded, low-resistance grounded, un- grounded, or of a compensated neutral point structure. They are suited for networks that are radial or looped, and for lines with single or multi-terminal feeds.
Page 28 1.2 Application Scope trolled, one binary input (single point indication) or two binary inputs (double point in- dication) may be used for this process. The capability of switching primary equipment can be restricted by a setting associat- ed with switching authority (Remote or Local), and by the operating mode (inter- locked/non-interlocked, with or without password request).
Page 29 1 Introduction munication that covers all of the information types required for protective and process control engineering. The integration of the devices into the power automation system SICAM can also take place with this profile. Besides the field-bus connection with PROFIBUS FMS, further couplings are possible with PROFIBUS DP and the protocols DNP3.0 and MODBUS.

2 Functions 2.2.8 Two-Phase Time Overcurrent Protection (non-directional only) Two-phase time overcurrent protection is used in isolated or resonant-grounded systems where interaction with existing two-phase protection equipment is required. Since an isolated or resonant-grounded system can still be operated with a ground fault in one phase, this protection function detects double ground faults with high ground fault currents.

Page 77 2 Functions The pickup value of the relay element 50-2 is set at address 1202, the assigned time 50-2 Element delay 50-2 DELAY at address 1203. This stage is often used for current grading in view of impedances such as transformers, motors or generators. It is specified such that it picks up for faults up to this impedance.
Page 78 2.2 Overcurrent Protection 50, 51, 50N, 51N short safety delay 50-2 DELAY (e.g. 100 ms). For faults on the outgoing feeders the element 50-2 is blocked. Both elements 50-1 or 51 serve as backup protection. The pickup values of both elements (50-1 PICKUP or 51 PICKUP and 50-2 PICKUP) are set equal.
Page 79 2 Functions The dropout times 1215 50 T DROP-OUT or 1315 50N T DROP-OUT can be set to Pickup Stabilization (Definite Time) implement a uniform dropout behaviour when using electromechanical relays. This is necessary for a time grading. The dropout time of the electromechanical relay must be known to this end.

For ground and grounded currents with grounded network, you can often set up a separate grading coordination chart with shorter delay times. The time multiplier can also be set to ∞. After pickup the element will then not trip. Pickup, however, will be signaled.

Page 83 2 Functions If the current exceeds the value set in address 2205 I Max, no further restraint will take place for the 2nd harmonic. The lower operating limit of the restraining function amounts to 0.25 times the sec- ondary nominal current of the fundamental harmonic (250 mA with 1 A sec. nominal current).

2 Functions Directional Overcurrent Protection 67, 67N With directional time overcurrent protection the phase currents and the ground current are provided with three elements. All elements may be configured independently from each other and combined according to the user's requirements. High-current elements 67-2 and overcurrent element 67-1 always operate with definite tripping time, the third element 67-TOC, operates with inverse tripping time.
Page 90 2.3 Directional Overcurrent Protection 67, 67N Figure 2-17 Overcurrent protection for parallel transformers For line sections supplied from two sources or in ring-operated lines the time overcur- rent protection has to be supplemented by the directional criterion. Figure 2-18 shows a ring system where both energy sources are merged to one single source.
Page 91 2 Functions rent elements or high-set elements the delay may be bypassed via a Manual Close pulse, thus resulting in high-speed tripping. Furthermore, immediate tripping may be initiated in conjunction with the automatic re- closure function (cycle-dependent). Pickup stabilization for the 67/67N elements of the directional time overcurrent protec- tion can be accomplished by means of settable dropout times.

The CTs must be of the same design and feature at least a separate core for high-im- pedance protection.

Function With three-phase connection, undervoltage protection uses the positive sequence fun- damental component or, optionally, also the actual phase-to-phase voltages.
Page 140 2.6 Voltage Protection 27, 59 The undervoltage protection works in an additional frequency range. This ensures that the protective function is preserved even when it is applied, e.g. as motor protection in context with decelerating motors. However, the r.m.s. value of the positive-se- quence voltage component is considered too small when severe frequency deviations exist.

2.17 Flexible Protection Functions (7SJ64 only) 2.17 Flexible Protection Functions (7SJ64 only) The flexible protection function is a general function applicable for a variety of protec- tion principles depending on its parameter settings. The user can create up to 20 flex- ible protection functions.
Page 265 2 Functions The maximum 20 configurable protection functions operate independently of each other. The following description concerns one function; it can be applied accordingly to all other flexible functions. The logic diagram 2-90 illustrates the description. The function can be switched ON and OFF or, it can be set to Alarm Only. In this Function Logic status, a pickup condition will neither initiate fault recording nor start the trip time delay.

2 Functions 2.19 Synchronism and Voltage Check 25 (7SJ64 only) The synchronization function is only available for device 7SJ64. It has configuration options for four different synchronization functions. The function and operation is de- scribed in the following using the SYNC Function group 1. The same applies to function groups 2 to 4.
Page 286 2.19 Synchronism and Voltage Check 25 (7SJ64 only) Figure 2-101 Bus coupler The synchronism check of 7SJ64 usually cooperates with the integrated automatic re- closing system and the control functions of the control function. It is also possible to employ an external automatic reclosing system. In such a case signal exchange between the devices is accomplished via binary inputs and outputs.
Page 287 2 Functions ditions it is not. The circuit breaker operating time is not taken into consideration. The SYNCHROCHECK mode is used. It corresponds to the classic synchrocheck function. On the other hand, asynchronous systems include bigger differences and the time window for switching passes relatively quick.

2.19 Synchronism and Voltage Check 25 (7SJ64 only) is smaller than Address 6x03 (lower voltage limit Vmin). The synchrocheck cannot be bypassed via binary input. If the monitoring function Fuse-Failure-Monitor is used and if it has picked up at the same time as the measurement of the synchronization was requested, the synchroni- zation is not started either (message „25 Sync.
Page 289: Synchronous / Asynchronous
2 Functions 2.19.1.3 Synchronous / Asynchronous The operating mode ASYN/SYNCHRON uses the frequency slip of the two power systems (parameter F SYNCHRON) to determine whether the power systems are asyn- chronous to each other ("Switching under Asynchronous System Conditions") or syn- chronous ("Switching under Synchronous System Conditions").
Page 290: De-Energized Switching
2.19 Synchronism and Voltage Check 25 (7SJ64 only) When the check has been terminated successfully, the device determines the next instant at which the two systems are in phase from the angle difference and the fre- quency difference. The ON command is issued at this instant minus the operating time of the circuit breaker.
Page 291: Direct Command / Blocking
2 Functions The associated messages indicating the release via the corresponding condition are as follows: „25 V1> V2<“, „25 V1< V2>“ and „25 V1< V2<“. Via binary input „>25 V1>V2<“, „>25 V1<V2>“ and „>25 V1<V2<“ release con- ditions can be issued externally provided the synchrocheck is controlled externally. Parameter TSUP VOLTAGE (address 6111) can be set to configure a monitoring time which requires above stated release conditions for de-energized connection to be ful- filled at least this time before switching is allowed.
Page 292: Interaction With Control, Ar And External Control
2.19 Synchronism and Voltage Check 25 (7SJ64 only) 2.19.1.7 Interaction with Control, AR and External Control With Control Basically, the synchrocheck interacts with the device control. The switchgear compo- nent to be synchronized is selected via a parameter. If an ON command is issued, the control takes into account that the switchgear component requires synchronism.
Page 293 2 Functions With AR The automatic reclosing (AR) function can also interact with the synchronizing func- tion. They are linked via the device control. The selection is made via parameter setting of the automatic reclosing function. The AR parameters (7138 Internal SYNC) determine which SYNC function group (SYNC FG) is used.

2.19 Synchronism and Voltage Check 25 (7SJ64 only) 2.19.1.8 Setting Notes General The synchrocheck function is only included in the 7SJ64 relay with its four voltage inputs. While setting the power system data 1 (see section 2.1.3.2) the device was already provided with data relevant for the measured values and the operating principle of the synchrocheck function.
Page 295 2 Functions Address 6x02SyncCB is used to select the switchgear component to which the syn- chronizing settings will be applied. Select the option none to use the function as ex- ternal synchronizing feature. It will then be triggered via binary input messages. Addresses 6x03Vmin and 6x04Vmax set the upper and lower limits for the operating voltage range V1 or V2 and thus determine the operating range for the synchronizing function.
Page 296 2.19 Synchronism and Voltage Check 25 (7SJ64 only) The parameter Balancing V1/V2 (address 6x21) can be set to account for different VT ratios of the two parts of the power system (see example in Figure 2-105). If a transformer is located between the system parts to be synchronized, its vector group can be accounted for by angle adjustment so that no external adjusting mea- sures are required.

Page 327 2 Functions since the remaining lifetime is decremented with each trip by the corresponding number of operating cycles. If one of the three phase values drops below the thresh- old, a corresponding message will be triggered. A double-logarithmic diagram provided by the CB manufacturer illustrates the relation- ship of operating cycles and tripping current (see example in Figure 2-118).
Page 328 2.23 Auxiliary Functions Note Since a directional coefficient of m < -4 is technically irrelevant, but could theoretically be the result of incorrect settings, it is limited to -4. If a coefficient is smaller than -4, the exponential function in the operating cycles diagram is deactivated. The maximum number of operating cycles with Isc (263 OP.CYCLES Isc) is used instead as the calculation result for the current number of operating cycles, see Figure 2-119.

With the ratio of the maximum number of switching cycles (n is n at I ) to the actual calculated number of switching cycles, you get the ratio of these concerning the maximum number of possible switching cycles in case of a tripping with rated operating current (I In the following example, the circuit breaker has tripped 100 times with rated operating current, 2 times with rated short-circuit current, and 3 times with 10 kA.

Page 629: Current Transformer Requirements
A Appendix Current Transformer Requirements The requirements for phase current transformers are usually determined by the over- current time protection, particularly by the high-current element settings. Besides, there is a minimum requirement based on experience. The recommendations are given according to the standard IEC 60044-1. The standards IEC 60044-6, BS 3938 and ANSI/IEEE C 57.13 are referred to for con- verting the requirement into the knee-point voltage and other transformer classes.

Note that the class accuracy according to IEC 61869-2 below 5% Irated (< 50 mA secondary) is not defined in general. For very sensitive directional measurements, Siemens recommends the classes 0.5S or 0.1S that define the class accuracy via an extended current range (up to 1% Irated) (see chapter 5.6.201.5, IEC 61869-2).
