At present, the feeder automation fault processing in China mainly adopts the following methods:
the self-adaptive comprehensive feeder automation realizes the fault location and isolation self-adaptation of the multi-branch multi-network distribution network frame by combining a non-voltage switching-off and incoming call delay switching-on mode, a short circuit/ground fault detection technology and a fault path priority processing control strategy and matching with the secondary switching-on of an outlet switch of a transformer substation, and the secondary switching-on restores the power supply of a non-fault section during the primary switching-on isolation fault interval.
The voltage-time feeder automation is realized by matching the working characteristics of a switch, namely no-voltage switching-off and incoming call delay switching-on, with the secondary switching-on of a transformer substation outgoing line switch, wherein the primary switching-on is used for isolating a fault section, and the secondary switching-on is used for recovering the power supply of a non-fault section.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, a feeder automation fault processing method based on a peer-to-peer communication mechanism includes feeder distribution terminals, the feeder distribution terminals constitute a feeder automation system through communication devices, the communication devices are optical fiber ethernet, the feeder distribution terminals communicate with each other peer-to-peer communication to automatically implement functions of fault location, isolation and power restoration of a non-fault area of a feeder, and report a processing process and a result to a distribution automation master station.
The method adopts a GOOSE peer-to-peer communication mode to realize peer-to-peer communication between the feeder line power distribution terminal and the feeder line power distribution terminal, the feeder line power distribution terminal can realize unified maintenance of topological parameters through unified configuration, and automatically generates and adapts to a distributed protection fixed value;
the configuration process of the feeder line power distribution terminal comprises the following steps:
the feeder line power distribution terminal can functionally support DSCADA, and also supports communication cooperation with adjacent feeder line power distribution terminals to complete specific distributed functions, such as fault location, fault isolation and the like.
And the feeder line power distribution terminal IED configuration tool imports the ICD model information into each feeder line power distribution terminal and configures corresponding SCD model information according to the actual static topological relation of the feeder lines.
Feeder distribution terminal IED configuration tool:
firstly, extracting GOOSE configuration information externally provided by a corresponding feeder line power distribution terminal according to terminal ICD model information in the SCD model information to generate GOOSE out data information of the feeder line power distribution terminal, such as: switch remote signaling information, fault signal information, virtual remote signaling information and the like;
thirdly, according to the terminal topological relation in the SCD model information, extracting the GOOSE data information of other feeder line power distribution terminals which need to be received by the feeder line power distribution terminal so as to generate GOOSEIN data information of the feeder line power distribution terminal and terminal CID model information, wherein the terminal CID model information comprises: model information corresponding to intAddr;
and finally, according to the terminal topological relation in the SCD model information, configuring the topological relation among the switches in the feeder line power distribution terminal and the topological relation between the feeder line power distribution terminal and other adjacent terminals to generate a final terminal model CID.
The fault processing method based on the peer-to-peer communication mechanism comprises the following steps:
as shown in fig. 2, the switch SW needs to be connected with other switches on two sides, so that the connection areas on two sides of the switch SW are defined as M side and N side respectively, the method is described according to the switch node of maximum 3 branches on each side, and if the node of more than 3 branches is actually applied, the method can be expanded with reference to the method. For the first and last switches, there are 1-side and only 1-side nodes on the M-side and N-side.
When all node switch configurations in the area are circuit breakers, the fast-acting distributed FA logic is applied; when all the node switch configurations are load switches, slow-acting distributed FA logic is applicable. In order to ensure that the intelligent distributed function of the primary system fault only acts once, the fault isolation logic should be designed into a charge-discharge state. When the power distribution network has a fault, if the phase current flowing through the node is greater than a setting fixed value or the zero-sequence current is greater than the setting fixed value, the node is judged to have a fault, and a 'node fault' GOOSE output signal is triggered instantly and is kept along with an overcurrent state, and meanwhile, in order to ensure the reliability, the shortest time for keeping the state after the signal is triggered is greater than 300 ms.
When the node detects that the system has a fault, if the node is not a last switch and the phase current is greater than a setting fixed value or the zero-sequence current is greater than the setting fixed value, and nodes on one side and only one side of the nodes on the M side and the N side do not send out a node fault GOOSE signal, the node switch is tripped after the set fault is cut off and delayed; if the node is a final switch, the phase current is greater than the setting fixed value or the zero-sequence current is greater than the setting fixed value, and a node fault GOOSE signal of any node of the M side and the N side is received, the node is tripped after setting delay.
If the node switch is not tripped in the switch failure time, the switch is triggered to reject the trip GOOSE output signal.
And if the node does not detect the fault and receives a 'node fault' GOOSE signal with only one node on the M side or the N side, the node switch is tripped after setting delay, and the last switch finishes fault isolation according to the logic requirement.
If the switch is switched off by a combined transformer and has no current in the time of switch failure, triggering a fault isolation success GOOSE output signal; if the node switch is not tripped in the switch failure time, the switch is triggered to reject the trip GOOSE output signal.
When the distributed FA function is switched on, the node is a first switch and GOOSE communication of the node is normal, if the switch is switched on and the voltage of the line is 3s, the first switch is automatically switched on for voltage loss protection, and the fault can be quickly isolated when the fault occurs between a power supply point and the first switch. And after the first switch is subjected to voltage loss protection, if the two sides of the node have no voltage and the node has no current, the node is tripped through setting delay, and the judgment of the tripping failure of the switch is started at the same time.
If the switch is switched off by a combined transformer and has no current in the time of switch failure, triggering a fault isolation success GOOSE output signal; if the node switch is not tripped in the switch failure time, the switch is triggered to reject the trip GOOSE output signal.
After the node switch trips due to conventional protection or distributed FA actions, the node switch is judged to be in switch failure and trip rejection after failure judgment time, and a 'switch trip rejection' GOOSE output signal is triggered to start an adjacent side switch. When the node receives a 'switch rejection' GOOSE signal of the node at the M side or the N side and the node switch is in an on position and is not tripped, the node switch is tripped by the malfunction joint tripping instantaneous action. If the node does not detect the fault and the trip is successful, triggering a GOOSE output signal of fault isolation success.
Other requirements for the switch failure joint trip logic are as follows:
1) when the node switch is a circuit breaker, the failure judgment time is 150 ms; when the node switch is a load switch, the failure judgment time is 300 ms.
2) And a switch bounce rejection GOOSE output signal sent to the adjacent side is widened for 300ms and then returned, so that the adjacent side switch can start a failure jump logic after reliably receiving the signal.
3) After the adjacent side switch fails and is in linkage trip with the node switch, if the node switch is rejected, the switch rejection GOOSE output signal is not triggered.
When the distributed FA is put into use and the GOOSE communication of the node is abnormal, the abnormal GOOSE communication overcurrent protection is automatically put into use for removing faults.
The GOOSE communication abnormal overcurrent protection is used for removing faults when lower-level faults of GOOSE communication abnormal nodes occur, and sharing a distributed FA fault removal overcurrent fixed value and a delay fixed value. If the GOOSE communication of the node is abnormal and the phase current is greater than the setting fixed value or the zero sequence current is greater than the setting fixed value, the node switch is tripped after setting delay, and if the node switch is not tripped in the switch failure time, the switch tripping-resistant GOOSE output signal is triggered.
Example 1:
the feeder automation system realizes the rapid fault location, isolation and power supply recovery of a closed-loop design and open-loop operation distribution network frame through locally acquired fault detection information and GOOSE information of adjacent switches, and the intelligent distributed terminal interoperation is illustrated by a typical distribution network automation case, and the intelligent distributed processing fault logic is illustrated by the following example.
CB1 and CB2 are substation side outlet switches, SW5 is a distribution interconnection switch, wherein SW1 and SW7 are first switches, and SW8 is a last switch.
As shown in fig. 3, when a fault occurs between SW1 and SW2, SW1 senses the fault current, and SW2-SW4, SW8 side does not sense the fault current;
as shown in fig. 4, the SW1 node is a first switch, and one side of the first switch is tripped by a fault removing action after no fault is delayed; one sides of the M side and the N side of the SW2 node have no fault, and one side has fault, and the fault isolation action trips after time delay; SW2-SW4 and SW8 have no fault and no fault on both sides, and do not act.
As shown in fig. 5, after the SW2 switch is successfully isolated by fault, a "fault isolation success" GOOSE signal is sent to both sides, the "fault isolation success" signal is forwarded to the open-loop point SW5 through SW3 and SW4, SW5 starts to close after receiving the signal and the voltage of one side is lost, and the power supply is successfully restored after the switch is closed after time delay.
The above description is only of the preferred embodiments of the present invention, and it should be noted that: it will be apparent to those skilled in the art that various modifications and adaptations can be made without departing from the principles of the invention and these are intended to be within the scope of the invention.
