8 Protection Busbar differential protection (87BB) Busbar differential protection represents the main protection function of the IED. It is characterized by a high measurement accuracy as well as flexible matching to most of busbar configurations. The operation is based on the percentage restraint principle with an extreme stability feature against heavy CT saturation caused by external fault. characteristic is a straight line inclined at 45. Any difference in phase relation of the fault currents leads to a lowering of the fault characteristic. The settable slope, Slope_BDiff is represented as a straight line with corresponding gradient and forms the operating characteristic. The differential current i Diff and the restraining current i Res are calculated in the IED according to following formula. The following definitions are applied for each phase. Operating characteristic Figure 1 illustrates the characteristic of busbar differential protection function. idiff where: n 1, n 2, n n: CT transformation ratios of various feeders connected to the busbar. The IED is informed about these values by user-defined settings I_BDiff K=1 Operating zone K=K_Diff The IED evaluates the differential current and the restraining current at consecutive sampling intervals. The busbar protection would issue a trip command if there are more than (N-2) samples fulfilling following condition in the program observation window: ires Figure 1 Characteristic of busbar differential where: protection i Diff: Busbar differential current i Res: Busbar restraint current I_BDiff: The sensitive threshold of pickup current of busbar differential protection K_Diff: Slope_BDiff, the settable slope of the characteristic If a short circuit occurs on the busbars whereby the same phase relation applies to all infeeding currents, then the fault The above mentioned calculation is performed in relevant bus zones as well as in check zone, respectively. The trip command can be issued only when both the faulty bus zone and the check zone are in operating area. Automatic ratio compensation CT ratios of in a busbar system may be different in various feeders, because the load conditions may be different in the feeders. The IED adjusts CT ratio of all 6

9 Protection feeders automatically, making the secondary currents fulfilling Krichhoff s current law (KCL). In order to insure the accuracy, the difference of CT ratios among various feeders should not be more than 4 times. Disconnector replica The IED confirms the disconnector status by monitoring the disconnector status contacts. For each disconnector, both the normally open status contact (NO) and normally close status contact (NC) are required. Based on the status of these two contacts, the IED can discriminate error of the contacts and then alarm or/and block the relevant bus zone of differential protection depending on the setting. If blocking protection is selected, the IED would issue an alarm signal and would block the protection. If no blocking is selected, only alarm signal would be issued and the protection would continue to its operation according to the previous healthy state of the disconnector before the contacts error. Circuit breaker status The feeder or coupler circuit breaker status contacts together with disconnector status contacts are used to determine the actual bus connection state for differential current calculation and indication of busbar connection Both normally open status contact and normally close status contact of circuit breakers of all feeders including bus coupler are connected to the IED. Based on the status of these two contacts, the IED can discriminate error of the contacts and then alarm until the error is cleared, and the protection would continue to its operation according the previous healthy state of the breaker before the contacts error. Current transformer open circuit supervision When an open circuit occurs in secondary circuit of current transformers, differential current appears in bus-section selective zones. Further, if the faulty current transformer corresponds to a feeder, differential current would further appear in check zone. The IED detects such a condition and issues respective alarm report. Moreover, it is possible to block busbar differential protection when a CT open circuit is detected. Differential current saturation supervision When an external fault occurs near the busbar, it may lead to current transformer saturation on the faulty feeder. The resulting differential current may cause the protection to maloperate if no measure is taken to detect saturation condition. To cope with the problem, the IED provides a sensitive element to detect current trans- -former saturation according to the wave- -form characteristics of differential and restraining current. In fact, secondary current can be transformed accurately, even by a saturated current transformer, when the current is near zero or at the initial instants of fault. At these instants, the differential current is zero. The IED adopts this characteristic to detect current transformer saturation. The CT saturation free time is only 2 ms. 7

10 Protection Sequence trip In case of bus coupler with only one CT, when a fault occurs between the CT and bus coupler circuit breaker while the circuit breaker is closed, the IED will trip the bus section near bus coupler circuit breaker instantaneously, and after a fixed time delay, if the bus coupler circuit breaker is opened, the IED will trip the other bus section. The tripping logic is illustrated in Figure 2. The protection operates separately for each feeder and coupler with dedicated settings. 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 or other transformer windings. Delay trip Instantaneous trip 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. Bus A IFAULT Bus B The current criteria are in combination with three phase current, zero and negative sequence current to achieve a higher security. 2 trip stages (local and surrounding breaker tripping) Related bus zone tripping in second stage Line A1 Legend: Line An Closed CB Line B1 Line Bm Figure 2 Trip logic to clear fault between coupler breaker and its CT 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. Transfer trip command to the remote line end in second stage Internal/ external initiation Single/three phase CBF initiation Current criteria checking (including phase current, zero and negative sequence current) 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. 8

11 Protection 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. 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 5. 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 4 9

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 Auxiliary contacts of circuit breaker and disconnector supervision Figure 5 Tripping logic for fault between coupler breaker and its CT Secondary system supervision Current transformer secondary circuit supervision Open circuited CT cores can cause unwanted operation of differential protec- -tion function. The interruption on CT secondary circuit can be detected by the IED. The IED provides following features: One stage for alarm One stage for block busbar differential protection Each stage can be selected and set separately Voltage transformer secondary The IED is connected with normally open contacts and normally close contacts of circuit breakers and disconnectors. It performs monitoring on the received information to detect any implausible status. If such a wrong status is detected for a disconnector, the IED will announce it after a settable time delay, and continue to operate according to previous healthy state of disconnector contacts. If the blocking function is enabled, the relevant bus zone of the busbar differential protection would be blocked until the wrong status changing to normal. Otherwise, the relevant bus zone of the busbar differential protection would not be blocked. If such a wrong status is detected for a circuit breaker, the device announces it after a settable time delay, and the protection will continue to operate according to previous healthy state of 10

14 Monitoring Self-supervision All modules can perform self- -supervision 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 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. 12

20 Hardware Modules Analogue Input Module (AIM) The analogue input module is used to galvanically separate and transform the secondary currents and voltages generated by the measuring transformers. CPU Module (CPU) The CPU module handles all protection functions and logic. There are two CPU modules in the IED, CPU1 and CPU2, with the same software and hardware. They work in parallel and interlock each other to prevent maloperation due to the internal faults of one CPU modules. Moreover, the redundant A/D sampling channels are equipped. By comparing the data from redundant sampling channels, any sampling data errors and the channel hardware faults can be detected immediately and the proper alarm and blocking is initiated in time. Communication Module (COM) The communication module performs communication between the internal protection system and external equipments such as HMI, engineering workstation, substation automation system, RTU, etc., to transmit remote metering, remote signaling, SOE, event reports and record data. Up to 3 channels isolated electrical or optical Ethernet ports and up to 2 channels RS485 serial communication ports can be provided in communication module to meet the communication demands of different substation automation system and RTU at the same time. The time synchronization port is equipped, which can work in pulse mode or IRIG-B mode. SNTP mode can be applied through communication port. In addition, a series printer port is also reserved. Binary Input Module (BIM) The binary input module is used to connect the input signals and alarm signals such as the auxiliary contacts of the circuit breaker (CB), etc. Binary Output Module (BOM) The binary output modules mainly provide tripping output contacts, initiating output contacts and signaling output contacts. All the tripping output relays have contacts with a high switching capacity and are blocked by protection startup elements. Each output relay can be configured to satisfy the demands of users.
