The inventor finds by the analysis to the compatibility of demarcation switch and feeder automation: when the generation single phase ground fault, demarcation switch can the automatism isolation user malfunction, can not exert an influence to feeder automation; When phase fault occured, demarcation switch and voltage-time type or with the cooperating of the concentrated feeder automation of reclosing did not need power distribution automation main website and switch definite value are made amendment, and can realize the automatism isolation of user malfunction; When demarcation switch with not with the cooperating of the concentrated feeder automation of reclosing, then need to revise the main website control method, otherwise can cause the block switch tripping operation locking of demarcation switch both sides, enlarge power failure range.
Propose a kind of concentrated feeder automation control method for the boundary troubleshooting based on the problems referred to above, used the method to can be good at solving the compatibility issue of demarcation switch and concentrated feeder automation.
Summary of the invention
The invention provides a kind of concentrated feeder automation control method for the boundary troubleshooting,, efficiently solve the compatibility issue of concentrated feeder automation and demarcation switch, avoid the accident interruption expanded range.
In order to address the above problem, the present invention is by the following technical solutions: a kind of concentrated feeder automation control method for the boundary troubleshooting, can be used for the compatibility issue that the concentrated feed line automatization system solves demarcation switch and concentrated feeder automation, it is characterized in that
Described concentrated feed line automatization system comprises:
Output in each transformer station arranges transformer station's wire-outgoing breaker, and distribution line of described each Substation control;
Connect by the concentrated interconnection switch between the different distribution lines, described concentrated interconnection switch is in open mode under normal conditions;
Be provided with some concentrated block switches at the distribution basic routing line, a demarcation switch is set in each user's syvfeeder road, described concentrated block switch and demarcation switch form communication connection with the power distribution automation main website respectively;
Described method comprises following process:
System's setting of power distribution automation main website: the T before exception handles starts is in the time, power distribution automation main website Real-Time Monitoring demarcation switch and concentrated block switch failure alarm signal, if monitor the demarcation switch alarm signal, T time backward transformer station wire-outgoing breaker sends " remote control combined floodgate " order, restores electricity; If T in the time, does not receive the demarcation switch alarm signal, start the concentrated exception handles;
Fault section isolation: when phase fault occurs certain user, transformer station's wire-outgoing breaker protection action tripping operation, this user's demarcation switch tripping operation and locking, realize the isolation of failed subs criber, whole concentrated block switches on the distribution wire at this user place detect fault current and sent stream information, demarcation switch and concentrated block switch can will be delivered to the power distribution automation main website simultaneously on the fault alarm signal, main station system generates event name;
Non-fault zone restores electricity: power distribution automation main website T monitoring in time after the transforming plant protecting tripping operation arrives this user demarcation switch fault alarm signal; T does not restart concentrated feeder automation exception handles after the time; directly send " remote control combined floodgate " order to transformer station's wire-outgoing breaker, recover the non-fault line power supply.
Preferably, the described T time is 30 seconds.
The present invention has the following advantages: performing step of the present invention is simple, can not only realize fast the processing to user's phase fault, and solved the compatibility issue of concentrated feeder automation and demarcation switch in process user phase fault process, avoid the accident interruption expanded range, improved the fail safe of transmission line.

Embodiment
A kind of concentrated feeder automation control method for the boundary troubleshooting provided by the invention can be used for the compatibility issue that the concentrated feed line automatization system solves demarcation switch and concentrated feeder automation, it is characterized in that,
Described concentrated feed line automatization system comprises:
Output in each transformer station arranges transformer station's wire-outgoing breaker, and distribution line of described each Substation control;
Connect by the concentrated interconnection switch between the different distribution lines, described concentrated interconnection switch is in open mode under normal conditions;
Be provided with some concentrated block switches at the distribution basic routing line, a demarcation switch is set in each user's syvfeeder road, described concentrated block switch and demarcation switch form communication connection with the power distribution automation main website respectively;
As shown in Figure 1, a kind of concentrated feeder automation control method for the boundary troubleshooting of the present invention comprises following process:
System's setting of power distribution automation main website: the T before exception handles starts is in the time, power distribution automation main website Real-Time Monitoring demarcation switch and concentrated block switch failure alarm signal, if monitor the demarcation switch alarm signal, T time backward transformer station wire-outgoing breaker sends " remote control combined floodgate " order, restores electricity; If T in the time, does not receive the demarcation switch alarm signal, start the concentrated exception handles;
Fault section isolation: when phase fault occurs certain user, transformer station's wire-outgoing breaker protection action tripping operation, this user's demarcation switch tripping operation and locking, realize the isolation of failed subs criber, whole concentrated block switches on the distribution wire at this user place detect fault current and sent stream information, demarcation switch and concentrated block switch can will be delivered to the power distribution automation main website simultaneously on the fault alarm signal, main station system generates event name;
