10 Protection Overcurrent protection (50, 51, 67) The protection provides following features: Two definite time stages One inverse time stage 11 kinds of IEC and ANSI inverse time characteristic curves as well as optional user defined characteristic Settable directional element characteristic angle to satisfy the different network conditions and applications Each stage can be set individually as directional/non-directional Each stage can be set individually for inrush restraint Cross blocking function for inrush detection Settable maximum inrush current First definite stage and inverse time stage can be set individually to alarm or trip VT secondary circuit supervision for directional protection. Once VT failure happens, the directional stage can be set to be blocked or to be non-directional Under voltage criteria checking (selectable), blocking of the definite time stages is possible when the measured voltage exceeds the threshold Inrush restraint function transformer energizing. In addition to considerably unbalanced fundamental current, inrush current comprises large second harmonic current which doesn t appear in short circuit current. Therefore, the inrush current may affect the protection functions which operate based on the fundamental component of the measured current. Accordingly, inrush restraint logic is provided to prevent overcurrent protection from mal-operation. Furthermore, by recognition of the inrush current in one phase, it is possible to set the protection in a way that not only the phase with the considerable inrush current, but also the other phases of the overcurrent protection are blocked for a certain time. This is achieved by cross-blocking feature integrated in the IED. The inrush restraint function has a maximum inrush current setting. Once the measuring current exceeds the setting, the overcurrent protection will not be blocked any longer. Characteristic of direction element The direction detection is performed by determining the position of current vector in directional characteristic. In other word, it is done by comparing phase angle between the fault current and the reference voltage, Figure 1 illustrates the direction detection characteristic for phase A element. The protection relay may detect large magnetizing inrush currents during 8

U BC_Ref Earth fault protection (50N, 51N, 67N) -I A Figure 1 Direction detection characteristic of overcurrent protection directional element The earth fault protection can be used to clear phase to earth faults as system back-up protection. The protection provides following features: where: Two definite time stages Ф Ph_Char: The settable characteristic angle The assignment of the applied measuring values used in direction determination has been shown in Table 1 for different types of faults. Table 1 Assignment of applied current and reference voltage for directional element Phase Current Voltage A B C I a Ib I c U bc U ca U ab For three-phase short-circuit fault, without any healthy phase, memory voltage values are used to determine direction clearly if the measured voltage values are not sufficient. The detected direction is based on the voltage of previously saved cycles.

It can be enabled/disabled by setting Each stage can be set individually as directional/non-directional Settable directional element characteristic angle to satisfy the different network conditions and applications Each stage can be set individually for inrush restraint Settable maximum inrush current Inrush restraint function adopting 2 nd harmonic measured phase or earth current (settable) 9

12 Protection First definite stage and inverse time stage can be set individually to alarm or trip VT secondary circuit supervision for directional protection function. Once VT failure happens, the directional stage can be set to be blocked or to be non-directional Zero-sequence current is calculated by summation of 3 phase currents or measured from earth phase CT selectable where: Ф 0_Char: The settable characteristic angle For earth fault protection, users can choose negative sequence directional element as the complement of zero sequence directional element. It can be used in case of too low zero sequence voltage due to some fault condition e.g. the unfavorable zero-sequence. The negative sequence directional element characteristic is shown in Figure 3. Directional element 3I 2 90 The earth fault protection adopts zero sequence directional element which compares the zero sequence system quantities: 3I 0, current is calculated from the sum of the three phase currentss or measured from earth phase CT 3U 0, the voltage is used as reference voltage, if it is connected. Otherwise, 3U 0, the zero sequence voltage, calculated from the sum of the three phase voltages Forward 3I I0 3U0_Ref Φ0_Char Bisector 0 Figure 2 Direction detection characteristic of zero sequence directional element Forward -3I 2 Φ2_Char 0 3U 2_ Ref Bisector Figure 3 Direction detection characteristic of where: negative sequence directional element Ф 2_Char: The settable characteristic angle Furthermore, under the VT failure situation, it can be set to block directional earth fault protection or to apply non-directional earth fault protection. Inrush restraint function The protection relay may detect large magnetizing inrush currents during transformer energizing. In addition to considerably unbalanced fundamental current, Inrush current comprises large second harmonic current which doesn t 10

13 Protection appear in short circuit current. Therefore, the inrush current may affect the protection functions which operate based on the fundamental component of the measured current. Accordingly, inrush restraint logic is provided to prevent earth fault protection from mal-operation. Since inrush current cannot be more than a specified value, the inrush restraint provides an upper current limit in which blocking does not occur. Neutral earth fault protection (50G, 51G) The neutral earth fault protection focuses on phase to earth faults. The measuring current is the one from dedicated neutral CT. The protection provides following features: Two definite time stages One inverse time stage 11 kinds of IEC and ANSI inverse time characteristic curves as well as optional user defined characteristic Each stage can be set individually to alarm or trip Neutral current is measured from dedicated neutral CT Sensitive earth fault protection (50Ns, 51Ns, 67Ns) The function provides a high sensitive earth fault protection for cables and high impedance grounded or isolated systems where single phase short circuit current is made by capacitive current. Furthermore, the function can operate with/without selective tripping according to fault direction. Sensitive earth fault protection integrated in the IED provides following features: Two definite time stages One inverse time stage 11 kinds of IEC and ANSI inverse time characteristic curves as well as optional user defined characteristic Sensitive earth fault directional element with 3U0/3I0-Φ principle Sensitive earth fault directional element with Cos Φ principle Settable directional element characteristic angle to satisfy the different network conditions and applications Each stage can be set to be directional, or non-directional independently Each stage can be set individually to alarm or trip Displacement voltage can be checked to increase function reliability Dedicated sensitive CT VT secondary circuit supervision for directional protection function For compensated-earthed system or high resistance earthed system with outgoing cable feeders, the directional protection is provided during a single phase fault. In general, for high impedance earthed system, whenever a feeder has a high capacitive current - normally one greater than 10% of the current limited by the 11

14 Protection neutral earthed impedance a simple sensitive earth fault relay is no longer enough to give sensitive and selective protection. In this case, the protection system for the feeder consists of a directional sensitive earth fault relay whose threshold can be set to below the capacitive current. In order to discriminate forward and reverse short circuits, the IED provides two methods for sensitive earth fault direction detection which should be utilized to cover all network configurations according to the type of grounding. The following characteristic is possible for directional detection: Directional sensitive earth fault detection based on U 0 /I 0 -Φ measurement (see Figure 4) INS Forward 90 -I NS ΦNS_Char Bisector 0 3U0_ Ref Figure 4 Direction detection characteristic of the sensitive earth fault directional element by where: U 0/I 0-Φ Ф NS_Char: The settable characteristic angle Based on current vector component (Cos Φ) measurement (see Figure 5). In this way, the relay is sensitive to the active residual current and insensitive to the capacitive current Forward IS 90 -I S 0 3U0_ Ref Figure 5 Direction detection characteristic of the sensitive earth fault directional element by Cos Φ A sensitive current transformer is provided to detect the small earth fault current (weak zero sequence current) in isolated networks or in networks with high earthed impedance where the earth fault current is extremely small. Negative-sequence overcurrent protection (46) Negative sequence (or phase unbalance) protection is essentially provided for the protection of generators, motors and feeders against unbalanced loading that may arise due to phase-to-phase faults. In addition, it is useful in detecting asymmetrical short circuits with magnitudes lower than the maximum load current, especially in delta side of the transformers. The protection provide following features: 12

15 Protection Two definite time stages component. One inverse time stage 11 kinds of IEC and ANSI inverse time characteristic curves as well as optional user defined characteristic The first definite stage and inverse stage can be set individually as alarm or trip stage Furthermore, this protection function may be used to detect interruptions, faults and polarity problems with CT. Thermal overload protection (49) The insulating material surrounding the windings ages rapidly if the temperature exceeds the design limit value. Thus, a thermal protection function is required to supplement the existing winding temperature device. The thermal overload protection estimates winding temperature and thus prevents it from thermal damaging. The memorized thermal overload protection operates based on an approximate replica of the temperature rise in the protected object caused by overload. The thermal replica can be implemented based on thermal models (Cold or Hot Curve) of IEC standard. The thermal overload in the IED is provided with one trip stage as well as one alarm stage. It is possible to set the alarm stage at a certain percentage of the setting value applied at the trip stage. The calculation is performed separately for each phase based on fundamental Overload protection (50OL) The IED supervises load flow in real time. If each phase current is greater than the dedicated setting for a set delay time, the protection will issue alarm or tripping. Overvoltage protection (59) The overvoltage protection detects abnormal network and machine high voltage conditions. Overvoltage conditions may occur possibly in the power system during abnormal conditions such as no-load, light load, or open line end on long line. The protection can be used as open line end detector or as system voltage supervision normally. The protection provides following features: Two definite time stages First stage can be set to alarm or trip Measuring voltage between phase-earth voltage and phase-phase (selectable) Three phase or single phase voltage connection Settable dropout ratio Undervoltage protection (27) The Undervoltage protection provides protection against dangerous voltage drops, especially for electric machines. 13

16 Protection The protection function provides following features: Two definite time stages optional user defined characteristic The first definite stage and inverse stage can be set to alarm or trip First stage can be set to alarm or trip Faulty phase discrimination Measuring voltage between phase-earth voltage and phase-phase selectable 3U 0 based on calculated summation of 3 phase voltage or measured injected residual voltage Current criteria supervision Circuit breaker aux. contact supervision VT secondary circuit supervision, the under voltage function will be blocked when VT failure happens Settable dropout ratio Displacement voltage protection (64) The displacement voltage protection is able to monitor the displacement voltage to detect the earth fault in power system. It is usually applied in non-solidly earthed networks where the earth fault current is limited. The displacement voltage 3U 0 can be either directly measured from VT or calculated based on connected three phases to earth voltages. In the latter case, the three voltages transformers input must be connected in an earth-wye configuration. The protection provide following features: Two definite time stages One inverse time stage 4 kinds of IEC inverse time characteristic curves as well as Breaker failure protection (50BF) The circuit breaker failure protection is able to detect a failure of the circuit breaker during a fault clearance. It ensures fast back-up tripping of surrounding breakers by tripping relevant bus sections. Once a circuit breaker operating failure occurs on a feeder/transformer, the bus section which the feeder/transformer is connected with can be selectively isolated by the protection. In addition a transfer trip signal is issued to trip the remote end circuit breaker of the feeder. In the event of a circuit breaker failure with a busbar fault, a transfer trip signal is issued to trip the remote end circuit breaker of the feeder. The current criteria are in combination with three phase currents, zero and negative sequence current to achieve a higher security. The function can be set to give three phase re-trip of the own breaker to avoid unnecessary tripping of surrounding breakers at an incorrect starting due to mistakes during testing. Two trip stages (local CB and surrounding breaker tripping) 14

17 Protection Transfer trip command to the remote line end in second stage Internal/ external initiation Three phase CBF initiation for sub-transmission system and distribution system Bus trip Settable CB Aux contacts checking Current criteria checking (including phase current, zero and negative sequence current) IFAULT Dead zone protection (50DZ) The IED provides dead zone protection to protect the area, between circuit breaker and CT in the case that CB is open, meaning dead zone. Therefore, by occurrence of a fault in dead zone, the short circuit current is measured by protection relay while CB auxiliary contacts indicate the CB is open. Line1 Line2 LineN Legend: Opened CB Closed CB Figure 6 Tripping logic when applying bus side CT Inter trip Busbar Internal/ external initiation Self-adaptive for bus side CT or line side CT When one bus side CT of feeder is applied, once a fault occurs in the dead zone, the IED trips the relevant busbar zone. Tripping logic is illustrated in Figure 6. When one line side CT is applied, when a fault occurs in the dead zone, protection relay sends a transfer trip to remote end relay to isolate the fault. Tripping logic is illustrated in Figure 7. IFAULT Line1 Line2 LineN Trip Relay Legend: Opened CB Closed CB Figure 7 Tripping logic when applying line side CT 15

18 Protection Synchro-check and energizing check (25) The synchro-check function checks voltages of the circuit breaker sides for synchronism conditions. The synchronization function ensures the stability of the network in three phase reclosing condition. To do this, the two side voltages of the circuit breaker are compared in terms of magnitude, phase angle and frequency differences. Additionally, closing can be done safely in conditions that at least one side of the CB has dead voltage. Available for automatic reclosing and manual closing (internally or externally) Based on voltage/ angle/ frequency difference Synchro-check conditions: Synch-check Energizing check, and synch-check if energizing check failure Override Modes of energizing check: Dead V 4 and dead V 3Ph Dead V 4 and live V 3Ph Live V 4 and dead V 3Ph Synchro-check reference voltage supervision If the automatic reclosing is set for synchronization check or energizing check, during the automatic reclosing period, the synchronization condition of the voltages between both sides of CB cannot be met, an alarm will be issued after default time delay. Auto-reclosing (79) For restoration of the normal service after a fault an auto reclosing attempt is mostly made for overhead lines. Experiences show that about 85% of faults have transient nature and will disappear after an auto reclosing attempt is performed. This means that the line can be re-energized in a short period. The reconnection is accomplished after a dead time via the automatic reclosing function. If the fault is permanent or short circuit arc has not disappeared, the protection will re-trip the breaker. Main features of the auto-reclosing are as follows: 4 shots automatic reclosing (selectable) Individually settable dead time for each shot Internal/external AR initiation Three phase AR operation CB ready supervision CB Aux. contact supervision Cooperation with internal synch-check function for reclosing command Unbalanced current or voltage protection (46) The purpose of the unbalance detection scheme is to remove fuse operated a capacitor bank from the network. This will prevent damaging overvoltage across the remaining capacitor units/elements where the fuse operation occurs. 16

19 Protection Unbalance detection scheme is set up to signal an alarm upon an initial failure in a bank. Upon subsequent critical failures, the bank will be tripped from the connected network. According to the used unbalanced voltage/current, the IED supports different protection schemes mentioned in the typical connections. The IED provides three analog channels to monitor unbalance status. If only one unbalanced channel is used, the other two channels can be reserved. To avoid mal-operation, breaker auxiliary contact is necessary as a criterion. Undercurrent protection (37) Under current protection is used to prevent reconnection of the charged capacitor bank to energized network when a short loss of supply voltage occurs. Once under current protection operates, the CB closing circuit will be interrupted and reset after a certain time. Additionally, time to resetting will be displayed on the HMI. Capacitor overload protection (50OL) The current overload protection is provided to protect the capacitor bank against the faults due to overvoltage which leads to dielectric breakdown. The tripping and alarming capability are provided and can be enabled or disabled separately. Load shedding function The IED provides three kinds of load shedding functions listed below. Under frequency load shedding protection The function monitors the network abnormality by detection of frequency reduction. When the system frequency falls down to a threshold frequency with following conditions satisfied, specified load will be removed. Under voltage checking Rate of frequency (df/dt) checking CB position checking Load current checking VT secondary circuit supervision Under voltage load shedding This kind of load shedding is to prevent the voltage collapse and uncontrolled loss of load. Low voltage load shedding is necessary when the network is connected with a huge system with vast power capacity. Under this condition, Low Frequency Load Shedding Scheme cannot work properly. Low Voltage Load Shedding Scheme" would be a useful criterion whenever Automatic Voltages Regulator (AVR) is out of service or not equipped with following conditions satisfied. Under voltage checking Negative sequence voltage checking Rate of voltage (du/dt) checking CB position checking 17

20 Protection Load current checking VT secondary circuit supervision Overload load shedding A Relay A The IED provides a load shedding function based on the load current passing through feeder. This function will be essential in conditions that feeder is connected to a huge network with constant frequency and additional AVR is continuously used for voltage regulation. In this case, load shedding protection should be done based on load current and monitoring of following items Under voltage checking Rate of voltage (du/dt) checking (in the case of voltage connection) Rate of frequency (df/dt) checking (in the case of voltage connection) VT secondary circuit supervision (in the case of voltage connection) Fast busbar protection scheme Relay B B Trip Relay C C GOOSE message-block Figure 8 operation when fault on the feeder C A Relay A Trip The IED provides fast busbar protection which is achieved based on operation with GOOSE signals, it is able to block the incoming feeder protection IED function by reception of a defined GOOSE signals from the outgoing feeder linked with the same busbar. B Relay B The principle illustrated in the following figure: If the fault occurs on outgoing feeder C, the protection IED C will trip and send block messenger to IED A to block IED A relevant protection function. C Relay C Figure 9 operation when fault on the Busbar 18

21 Protection Once the fault located on the busbar, there is not one protection IED of outgoing feeder to trip and block the IED A. So the IED A will trip and clear off the fault with short time delay. Secondary system supervision Current transformer secondary circuit supervision Open or short circuited CT cores can cause unwanted operation of some protection functions such as earth fault current and negative sequence current functions. Interruption of the CT secondary circuit is detected based on zero-sequence current. Once CT failure happens, each stage of earth fault protection is blocked. Voltage transformer secondary circuit supervision A measured voltage failure, due to a broken conductor or a short circuit fault in the secondary circuit of voltage transformer, may result in unwanted operation of the protection functions which work based on voltage criteria. VT failure supervision function is provided to block these protection functions and enable the backup protection functions. The features of the function are as follows: Symmetrical/asymmetrical VT failure detection 3-phase AC voltage MCB monitoring 1-phase AC voltage MCB monitoring Zero and negative sequence current monitoring Applicable in solid grounded, compensated or isolated networks 19

22 Control The primary apparatuses, such as circuit breaker, disconnector, earth disconnector, etc, can be controlled through IED in two modes, Remote mode: By Substation automation system Local mode: by dedicated keys operation on the front plate of IED, for advanced IED version only Remote or local mode can be switched by L/R key on the IED front plate. The current control mode is indicated on the LCD as an icon, L or R. All control operations are supervised under interlock logic according the requirement. The interlock logic can be programmed in the software tool by user (shown in Figure 11). For advanced IED version, the single line diagram can be displayed on the LCD (shown in Figure 11), which is able to indicate the status of circuit breaker, disconnector and other in real time.

23 Monitoring Phase-sequence of voltage and current supervision The phase-sequence of three phase voltage and current are monitored in the normal condition to determine that the secondary circuit of CT or VT is connected with IED correctly. 3I0 polarity supervision The IED compare the magnitude and phase angle of the calculated zero sequence current with the measured one to determine that the polarity is connected in a right way. The third harmonic of voltage supervision If the third harmonic voltage is excessive, the alarm without blocking protection will be given with delay time for checking of the secondary circuit of voltage transformer. Auxiliary contacts of circuit breaker supervision Current flowing through the transmission line and connected CB aux. contacts are monitored in phase segregated. Therefore, the conflict condition is reported as alarm. For example, If CB aux. contacts indicate that CB is open in phase A and at the same time flowing current is measured in this phase, related alarm is reported. Broken conductor detection The main purpose of the broken conductor detection function is to detect the broken conductors on protected transmission lines and cables. Detection can initiate an alarm or tripping. Self-supervision All modules can perform selfsupervision to its key hardware components and program, as soon as energizing. Parts of the modules are self-supervised in real time. All internal faults or abnormal conditions will initiate an alarm. The fatal faults among them will result in the whole IED blocked The sampled data from the redundant A/D sampling channels compare with each other in real time. If the difference exceeds the specified threshold, it will be considered as analog input channel fault and the protection will be blocked immediately CPU module and communication module perform real time inter- -supervision. Therefore communication interruption between them is detected and related alarm will be given CRC checks for the setting, program and configuration, etc. Fault locator The built-in fault locator is an impedance measuring function giving the distance from the IED measuring location to the fault position in km. The IED reports fault location after the IED tripping. 21

24 Communication Station communication Overview The IED is able to connect to one or more substation level systems or equipments simultaneously, through the communication ports with communica- -tion protocols supported. (Shown in Figure 12) Front communication port There is a serial RS232 port on the front plate of all the IEDs. Through this port, the IED can be connected to the personal computer for setting, testing, and configuration using the dedicated Sifang software tool. RS485 communication ports Up to 2 isolated electrical RS485 communication ports are provided to connect with substation automation system. These two ports can work in parallel for IEC Ethernet communication ports Up to 3 electrical or optical Ethernet communication ports are provided to connect with substation automation system. These two out of three ports can work in parallel for protocol, IEC61850 or IEC Server or Work Station 1 Server or Work Station 2 Work Station 3 Switch Work Station 4 Net 1: IEC61850/IEC103,Ethernet Port A Switch Net 2: IEC61850/IEC103,Ethernet Port B Switch Switch Switch Gateway or converter Switch Gateway or converter Net 3: IEC103, RS485 Port A Net 4: IEC103, RS485 Port B Figure 12 Connection example for multi-networks of station automation system Note: All four ports can work in parallel Communication protocol The IED supports station communication with IEC and IED protocols. By means of IEC61850, GOOSE peer- -to-peer communication make it possible that bay IEDs can exchange information to each other directly, and a simple master-less system can be set up for bay and system interlocking and other interactive function. Time synchronization port 22

25 Software Tools All IEDs feature a permanently integrated electrical time synchronization port. It can be used to feed timing telegrams in IRIG-B or pulse format into the IEDs via time synchronization receivers. The IED can adapt the second or minute pulse in the pulse mode automatically. Meanwhile, SNTP network time synchro- -nization can be applied. Figure 13 illustrates the optional time synchronization modes. SNTP IRIG-B Pulse Ethernet port IRIG-B port Binary input Figure 13 Time synchronizing modes 23
