In order further to explain in detail the act in collusion to make each other's confessions method of transformer station automatic closing power supply of the present invention, to adopt a plurality of specific embodiments and Fig. 3 below, explain in detail the act in collusion to make each other's confessions method difference with the prior art of transformer station's automatic closing power supply of the present invention, with and the beneficial effect that brings.
Be illustrated in figure 3 A, B, C3Ge 110kV transformer station 520 by two 220kV stations 510 by the act in collusion to make each other's confessions modes of operation of double-circuit line, figure comprises that the circuit breaker 550 of co-bit state is, the circuit breaker 540 of a minute state and on the spot type backup auto-activating device 530.In this specific embodiment, to have the mode of connection that 2 or 2 above transformer stations act in collusion to make each other's confessions by same power supply all applicable to similar for the method that realizes the automatic closing power supply of statements based on collusion transformer station.
As shown in Figure 3, by traditional prepared auto restart action logic, when fault point 1 is the circuit generation permanent fault between 220kV station 510 and 110kV A station, 110kV A, B, C San Ge transformer station all become with no pressure, the transformer station of now open loop operation is that the main line switching that supplies of the backup auto-activating device action tripping at 110kV C station is this side switch of circuit between 110kV B station and 110kV C station, and the available line switching that closes is that this side switch of circuit between 110kV C station and 110kV D station is with the power supply at recovery 110kV C station.Because of 110kV C station side switch first tripping before backup auto-activating device drops into Backup Power Switch of circuit between 110kV B station and 110kV C station, after prepared auto restart action, 110kV A station and 110kV B station cannot restore electricity.
By 3 110kV transformer stations 520 of above-mentioned example, by 220kV station 510, by the double-circuit line mode of moving of act in collusion to make each other's confessions, applied, can be by following consideration on definite value arranges: the 110kV A 220kV station 510 of adjusting at station is main for circuit with the circuit between 110kV A station, closing a floodgate in the fault delayed setting that accelerates motion is 0.3s; The circuit that 110kV B adjusts at station between 110kV A station and 110kV B station is main for circuit, and closing a floodgate in fault accelerated motion delayed setting is 0.6s; The circuit that 110kV C adjusts at station between 110kV B station and 110kV C station is main for circuit, and closing a floodgate in fault accelerated motion delayed setting is 0.9s.By the backup auto-activating device action logic of standardization logical design, the backup auto-activating device at 110kV C station according to 110kV B station and line switching between 110kV C station be co-bit and 110kV C station with 110kV D station between line switching for dividing, automatically be identified as open loop operating point, while meeting prepared auto restart charging modes, complete prepared auto restart charging.The backup auto-activating device at 110kV A station, 110kV B station is identified as non-open loop operating point according to accessed line switching in co-bit, does not carry out the charging of prepared auto restart mode.
By above-mentioned example, as shown in Figure 3 during the 1 place's circuit generation permanent fault of fault point, if the line configuring between 220kV station 510 and 110kV A station in full line range, can move rapidly the protection of excising faulty line both sides switch during any point fault, as conventional optical fiber differential protective, after the backup auto-activating device action of described standardization logical design, all transformer station restores electricity, by the backup auto-activating device action logic of standardization logical design, the backup auto-activating device action behavior of each transformer station is as follows: after fault point 1 place's fault occurs, the both sides switch of route protection action excision 220kV station 510 and 110kV A intersite line is with isolated fault, while 110kV A, B, C San Ge transformer station all becomes with no pressure.The backup auto-activating device at 110kV C station automatically identifies that our station bus is with no pressure, circuit is without stream, the condition that meets " with no pressure without stream " starts, after the action delay of adjusting, the action extension wire that closes is the line switching between standing with 110kV D in 110kV C station, and open 10s judgement is closed a floodgate in the function of fault accelerated motion, but because excising fault point, do not meet the condition of closing a floodgate in fault accelerated motion, without closing a floodgate, in fault, accelerate motion.When the backup auto-activating device at 110kV A station, 110kV B station closes line switching between standing of 110kV C station and 110kV D at 110kV C station, voltage has pressure from no pressure becoming, meeting " change with no pressure has pressure " condition starts, and open 10s judgement is closed a floodgate in the function of fault accelerated motion, but because excising fault point, do not meet the condition of closing a floodgate in fault accelerated motion, without closing a floodgate, in fault, accelerate motion.After above-mentioned backup auto-activating device has moved, 110kV A, B, C San Ge transformer station all transfer to by 110kV C station by 220kV 510 powered operations of standing.
By above-mentioned example, as shown in Figure 3 during the 1 place's circuit generation permanent fault of fault point, if 220kV station 510 and circuit between 110kV A station can move rapidly the protection of excising faulty line both sides switch while not configuring in full line range any point fault, the switch that while being fault point 1 place's circuit generation permanent fault, faulty line 220kV station 510 these sides are only excised in protection action is with isolated fault, by the backup auto-activating device action logic of standardization logical design of the present invention, the backup auto-activating device action behavior of each transformer station is as follows: after fault point 1 place's fault occurs, the mains side switch of route protection action excision 220kV station 510 and 110kV A intersite line is with excision fault, while 110kV A, B, C San Ge transformer station all becomes with no pressure.The backup auto-activating device at 110kV C station automatically identifies that our station bus is with no pressure, circuit is without stream, the condition that meets " with no pressure without stream " starts, after the action delay of adjusting action close extension wire be 110kV C station with 110kV D station between line switching, and the open 10s judgement function of closing a floodgate and accelerating motion in fault.When the backup auto-activating device at 110kV A station, 110kV B station closes line switching between standing of 110kV C station and 110kV D at 110kV C station, voltage has pressure from no pressure becoming, meet " change with no pressure has pressure " condition and start, and open 10s judgement is closed a floodgate in the function of fault accelerated motion.Because 220kV station 510 and the switch of 110kV A intersite line by 110kV A station side do not disconnect, the prepared auto restart action at the 110kV C station fault current after extension wire switch that closes is stood by 110kV D by 220kV station 510, C station, B station, A station flows to 1 place, fault point, 110kV A station, 110kV B station, the backup auto-activating device at 110kV C station closes a floodgate and all meets in the criterion of fault accelerated motion simultaneously, but adjust as 0.3s in fault accelerated motion time delay 110kV A station owing to closing a floodgate, 110kV B adjusts at station as 0.6s, 110kV C adjusts at station as 0.9s, the backup auto-activating device that after 0.3s, 110kV A stands closes a floodgate and excises in fault accelerated motion adjust main is the switch of 220kV station 510 and 110kV A intersite line for line switching, after switch trip, fault point isolates, 110kV B station, the backup auto-activating device at 110kV C station meets to close a floodgate and returns in the condition of fault accelerated motion before action delay arrives.Therefore,, after above-mentioned backup auto-activating device has moved, 110kV A, B, C San Ge transformer station equally all can transfer to by 110kV C station by 220kV 510 powered operations of standing.
By above-mentioned example, as shown in Figure 3 during the 2 place's circuit generation permanent fault of fault point, the backup auto-activating device action behavior at 110kV B station, 110kV C station and the above-mentioned prepared auto restart action behavior that 110kV A stands, 110kV C stands are similar, as shown in Figure 3 during the 3 place's circuit generation permanent fault of fault point, the prepared auto restart action behavior that the backup auto-activating device action behavior at 110kV C station and above-mentioned 110kV C stand is similar, does not repeat them here.
By above scheme, can be found out, the act in collusion to make each other's confessions method of transformer station automatic closing power supply of the present invention, by taking backup auto-activating device when action directly to close extension wire switch, whether open combined floodgate closes a floodgate in fault in fault accelerated motion Function detection again, the backup auto-activating device of each transformer station's installing closes a floodgate in the time delay of fault accelerated motion function by differential fiting tuning, device the closer to power supply point closes a floodgate shorter in fault accelerated motion time delay fixed value adjusting, to reach the object of isolated fault step by step, realized statements based on collusion transformer station and by prepared auto restart, realized the demand that maximum magnitude restores electricity when former power supply fault.The act in collusion to make each other's confessions method of transformer station automatic closing power supply of the present invention, go for 2 or 2 modes of connection that above transformer station acts in collusion to make each other's confessions by same power supply, for concrete operational mode, each device arranged to suitable main confession line switching and close a floodgate in fault accelerated motion time delay definite value, can realize statements based on collusion electrical network moves by prepared auto restart the transformer station that will be correlated with and is converted to by stand-by power supply and powers when power failure, the reliability that has improved fail safe and the power supply of electrical network, has good economic benefit.
