Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
The embodiment of the present invention provides a kind of distribution network failure processing method adopting region locking, the method is: for the every platform platform intelligent switch in power distribution network arranges two GOOSE multicast address, two that simultaneously described two GOOSE multicast address are distributed to respectively that described every platform intelligent switch connects adjacent the first distribution regions and the second distribution region; When power distribution network break down and electric current from the first distribution field flow orientation second distribution region time, intelligent switch between two distribution regions sends block signal to a GOOSE multicast address, and the intelligent switch in the first distribution region that a described GOOSE multicast address is corresponding carries out locking after receiving block signal.
The method also comprises: when power distribution network break down and electric current from the second distribution field flow orientation first distribution region time, intelligent switch between two distribution regions sends block signal to the 2nd GOOSE multicast address, and the intelligent switch in the second distribution region that described 2nd GOOSE multicast address is corresponding carries out locking after receiving block signal.
After described intelligent switch carries out locking after receiving block signal, the intelligent switch between two distribution regions sends sub-gate signal to GOOSE multicast address, and after described intelligent switch receives sub-gate signal, described intelligent switch separating brake locking are closed a floodgate.
After described intelligent switch receives sub-gate signal, when described intelligent switch is in gate-dividing state, the direct locking of described intelligent switch is closed a floodgate.
Described block signal is divided into the first block signal, the second block signal, when described intelligent switch to receive after the first block signal after the latch switch very first time just separating brake again; Described intelligent switch to receive after the second block signal after latch switch second time just separating brake again, and described second time is greater than the very first time.
With in the typical distribution net shown in Fig. 1, S1, S2 are transformer station's outlet switch, and D11, D12, D13, D14, Z11, D21, D22 are block switch, and L is interconnection switch.For each block switch and interconnection switch are equipped with voltage, current transformer and have the IED of protection, controlling functions and GOOSE communication function in the present invention, thus formation intelligent switch, realize voltage, the collection of electric current and the automatic divide-shut brake of switch.
Defining the power distribution network surrounded by one group of switch adjacent on circuit is a distribution region (abbreviation region), as shown in phantom in Figure 1.If definition Z(D1, D2 ... Dx) represent by switch D1, D2 ..., the distribution region that surrounds of Dx, then can be divided into 9 distribution regions in Fig. 1, be respectively Z(S1, D11), Z(D11, D12, Z11), Z(Z11,0), Z(D12, D13), Z(D13, D14), Z(D14, L), Z(S2, D21), Z(D21, D22), Z(D22, L), wherein 0 represent line end.
For each distribution region allocation GOOSE multicast address, be respectively MAC(S1, D11), MAC(D11, D12, Z11), MAC(Z11, 0), MAC(D12, D13), MAC(D13, D14), MAC(D14, L), MAC(S2, D21), MAC(D21, D22), MAC(D22, L), multicast address is used for filtering and receiving GOOSE message, when certain GOOSE multicast address is sent information as destination address by intelligent switch, the IED being provided with this multicast address all can receive this message, and other intelligent switchs not arranging this multicast address all do not receive this message.As shown in fig. 1, such as intelligent switch D11, D12, Z11 is provided with MAC(D11, D12, Z11) multicast address, when intelligent switch D12 sending destination location is MAC(D11, D12, during GOOSE message Z11), then only have D11, Z11 to receive this message, other intelligent switchs do not receive.
Because every platform intelligent switch connects two adjacent distribution regions, be referred to as the first distribution region and the second distribution region, therefore two GOOSE multicast address are set for every platform intelligent switch, be respectively a GOOSE multicast address and the 2nd GOOSE multicast address, one GOOSE multicast address is the GOOSE multicast address in the first distribution region, and the 2nd GOOSE multicast address is the GOOSE multicast address in the second distribution region.For the adjacent area of D12, D12 in Fig. 1 for Z(D11, D12, Z11) and Z(D12, D13), if with Z(D11, D12, Z11) as the adjacent first distribution region of D12, then the second distribution region is Z(D12, D13).Intelligent switch D12 can arrange two GOOSE multicast address, is respectively MAC(D11, D12, Z11) and MAC(D12, D13), MAC(D11, D12, Z11) corresponding first distribution region, MAC(D12, D13) corresponding second distribution region.
Every platform intelligent switch gathers voltage, the electric current of circuit, and identify the sense of current, there are two kinds of senses of current in the electric current then flowing through arbitrary switch: direction one is for flow into the second distribution region by the first distribution region, and direction two is for flow into the first distribution region by the second distribution region.When a failure occurs it, if the sense of current is for flow into the second distribution region by the first distribution region, then intelligent switch sends block signal on a GOOSE multicast address, that is sends block signal to the first distribution region; If the sense of current is for flow into the first distribution region by the second distribution region, then intelligent switch sends block signal on the 2nd GOOSE multicast address, that is sends block signal to the second distribution region; If fault current do not detected, then do not send block signal to any multicast address.Such as, for described intelligent switch D12, if detect, fault current is by Z(D11, D12, Z11) field flow orientation Z(D12, D13) region, then with MAC(D11, D12, Z11) multicast address sends block signal as destination address.
After other intelligent switchs in described distribution region receive block signal, latch switch certain hour, and the intelligent switch surrounding fault zone can not receive block signal, then can separating brake immediately, and sub-gate signal is sent to reciprocal GOOSE multicast address while separating brake, allow switch trip fault current not detected, thus isolated fault point fast, and unlikelyly cause overstep tripping.
Embodiment:
The fault treating procedure that the present invention is concrete.
(1) open loop distribution network failure processing method
For F point failure in the open loop power distribution network shown in Fig. 2, fault point is between D13 and D14.Transformer substation switch S1 does not possess the function of intelligent switch, and S1 arranges the backup protection of 0.3s time delay (time differential time delay) as this circuit, after breaking down; be Z(S1 for D11 fault current direction; D11) Z(D12, D13 is flowed to), be Z(D11 for D12 fault current direction; D12; Z11) Z(D12, D13 is flowed to), be Z(D12 for D13 fault current direction; D13) Z(D13, D14 is flowed to).Therefore, D11 detects after fault current immediately to MAC(S1, D11) X1 block signal (although S1 can not receive) is sent, D12 detects after fault current immediately to MAC(D11, D12, Z11) send X1 block signal, D13 after fault current being detected immediately to MAC(D12, D13) send X1 block signal.
Consider from reliability perspectives, in conservative situation, IED in intelligent switch can detect fault current in t1=20ms after fault occurs, GOOSE message transmission can be transmitted in t2=10ms, the tripping operation exit relay of IED is less than t3=15ms operate time, switch adopts circuit breaker can tripping in t4=60ms, and IED can detect in t5=20ms that after failure removal fault current disappears.Order, Td=t4+t5.
Because the intelligent switch surrounding fault zone can not receive block signal, therefore each intelligent switch judges whether to receive X1 block signal in t1+t2=30ms, if do not received, as the D13 in Fig. 2 (a), then drive tripping operation exit relay, total Outlet time is less than T0=t1+t2+t3=45ms, can excise fault in T0+t4=105ms.
In Fig. 2 (a), D11, D12 switch can receive X1 block signal and illustrate that fault is in other regions, D11, D12 need the fault clearing time escaping D13 switch, then after fault occurs, drive outlet during T1=T0+Td=125ms, the selectivity of D13 switch can be ensured like this, take into account D13 also can excise according under emotionally condition, reduce power failure range to greatest extent, now the fault clearing time of D11, D12 is T1+t4=185ms simultaneously.
As shown in Figure 2 (b), D11, D12 in t1+t2=30ms once receive X1 signal, send X2 block signal immediately elsewhere, after D11 switch receives X2 signal, drive outlet during T2=T1+Td=205ms after Outlet time time delay being occurred to fault, when can ensure that D12 excises fault in support like this, D11 can not malfunction.D12 is also occurred can not consider according to dynamic low probability complex situations.
When reclosing does not drop into, D13 tripping operation simultaneously will to fault current reciprocal region Z(D13, D14) send X3 separating brake block signal, as shown in Figure 2 (c), locking D14 closes a floodgate, thus isolated fault region.When reclosing drops into, carry out reclosing after D13 tripping, successful reclosing recovers normal operating mode; Reclosing failure D13 Accelerated trip, and as shown in Figure 2 (c) to fault current reciprocal region Z(D13, D14) sending X3 separating brake block signal, locking D14 closes a floodgate, thus isolated fault region.
Fig. 2 (d) is depicted as D13 and occurs according to dynamic situation, and D13 occurs according to will immediately to fault current reciprocal region Z(D13, D14 after dynamic) send X3 separating brake block signal, locking D14 closes a floodgate.D12 as the standby of D13 after T1+t4=185ms tripping, when reclosing does not drop into, D12 is to the reciprocal region Z(D12 of fault current, D13) X3 separating brake block signal is sent, notify D13 separating brake and locking combined floodgate, although D13 separating brake does not affect Fault Isolation according to dynamic, Fault Isolation scope now comprises Z(D12, D13) and Z(D13, D14).When reclosing drops into, carry out reclosing after D12 tripping, successful reclosing recovers Z(D12, D13) and Z(D13, D14) run.Interconnection switch L detects after the decompression of side through time delay T
lclose a floodgate, as shown in Fig. 2 (e), recover Z(D14, L) power supply in region, T
lthe time that above-mentioned fault occurs to reclosing failure should be greater than.
Processing method time breaking down in other regions and roughly the same above-mentioned, set forth no longer one by one herein, it should be noted that, when fault point is between block switch and interconnection switch, interconnection switch can be blocked, and does not close a floodgate.
(2) closed loop power distribution net fault handling method
For F point failure in the closed loop ring power distribution network shown in Fig. 3 (a), interconnection switch L is in "on" position, and fault point is between D13 and D14.Transformer substation switch S1, S2 arrange 0.3s time delay, and after fault occurs, D11 is to MAC(S1, D11) send X1 block signal, D12 is to MAC(D11, D12, Z11) send X1 block signal, D13 is to MAC(D12, D13) send X1 block signal, and D14 is to MAC(D14, L) send X1 block signal, L is to MAC(D22, L) send X1 block signal, D22 is to MAC(D21, D22) send X1 block signal, D21 is to MAC(S2, D21) send X1 block signal.
Equally, IED can detect fault current in t1=20ms after fault occurs, GOOSE message transmission can be transmitted in t2=10ms, the tripping operation exit relay of IED is less than t3=15ms operate time, switch can trip in t4=60ms, and IED can detect in t5=20ms that after failure removal fault current disappears.Order, Td=t4+t5.
Because the intelligent switch surrounding fault zone can not receive block signal, therefore each intelligent switch judges whether to receive X1 block signal in t1+t2=30ms, if do not received, as D13 and D14 in Fig. 3 (a), then drive tripping operation exit relay, total Outlet time is less than T0=t1+t2+t3=45ms, can excise fault in T0+t4=105ms.
In Fig. 3 (a), except S1, S2, Z11, D13, D14, other intelligent switchs can receive X1 block signal, first drive outlet during time delay T1=T0+Td=125ms, can ensure the selectivity of D13, D14 switch like this, the fault clearing time through the switch of T1 time delay is T1+t4=185ms.
As shown in Figure 3 (b), the intelligent switch receiving X1 signal sends X2 block signal immediately elsewhere, outlet is driven during T2=T1+Td=205ms after Outlet time time delay occurs to fault by switch D11, D22, D21 of receiving X2 signal, can ensure that D12, L excise fault in support like this, and other switches can not malfunction.D12, L are also occurred can not consider according to dynamic low probability complex situations.
When reclosing does not drop into, D13 tripping operation simultaneously will to the reciprocal region Z(D13 of fault current, D14) X3 separating brake block signal is sent, D14 tripping operation simultaneously will to the reciprocal region Z(D13 of fault current, D14) X3 separating brake block signal is sent, as shown in Figure 3 (c), D13 and D14 receives X3 signal block and closes a floodgate, thus isolated fault region.When reclosing drops into, carry out reclosing after D13 and D14 tripping, successful reclosing recovers normal operating mode; Reclosing failure D13, D14 trip, and send X3 separating brake block signal as shown in Figure 3 (c), and locking D13, D14 close a floodgate, thus isolated fault region.
Fig. 3 (d) is depicted as D13 and occurs according to dynamic situation, and D13 occurs according to will immediately to fault current reciprocal region Z(D13, D14 after dynamic) send X3 separating brake block signal, locking D14 closes a floodgate.D12 is as after the standby tripping of D13, when reclosing does not drop into, D12 is to the reciprocal region Z(D12 of fault current, D13) send X3 separating brake block signal, notify D13 separating brake and locking combined floodgate, although D13 separating brake does not affect Fault Isolation according to dynamic, Fault Isolation scope now comprises Z(D12, D13) and Z(D13, D14), as shown in Fig. 3 (e).When reclosing drops into, carry out reclosing after D12 tripping, successful reclosing recovers Z(D12, D13) and Z(D13, D14) run, but now D14 is in separating brake blocking always, operation with closed ring has become open loop operation, but does not affect power supply, and recovering former running status needs artificial treatment.
(3) single supply radial distribution networks fault handling method
To the radial distribution networks of single power supply, electric current only has a kind of direction, when breaking down, sends block signal, can realize Fault Isolation directly to the GOOSE multicast address of specifying.The radial distribution networks of single power supply as shown in Figure 4, because electric current only exists a direction, therefore each intelligent switch only detects overcurrent, does not need to gather voltage and carrys out the failure judgement sense of current.When breaking down, D1 is only to Z(S1, D1) region sends GOOSE message, and D2 is only to Z(D1, D2, Z1) region sends GOOSE message, D3 is only to Z(D2, D3) region transmission GOOSE message, fault handling method is as identical in (1) open loop distribution network failure processing method, can only Fault Isolation be realized, the power supply of interconnection switch L combined floodgate can not be realized.
The present invention can realize fault and isolate fast, and the restoring electricity of non-faulting district, and compared with prior art, can not cause overstep tripping, and arranges simple, and practical application is strong.
The above, be only preferred embodiment of the present invention, be not intended to limit protection scope of the present invention.
