Inventor is found by the analysis of the compatibility to demarcation switch and feeder automation: when there is single phase ground fault, and demarcation switch can automatism isolation user malfunction, can not have an impact to feeder automation; When there is phase fault, demarcation switch and voltage-time type or the coordinating of concentrated feeder automation with reclosing, not needing to modify to power distribution automation main website and switch definite value, the automatism isolation of user malfunction can be realized; When coordinating of demarcation switch and the concentrated feeder automation not with reclosing, then need amendment main website control method, otherwise the block switch tripping operation locking of demarcation switch both sides can be caused, expand power failure range.
Propose a kind of concentrated feeder automation control method for troubleshooting of demarcating based on the problems referred to above, use 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 troubleshooting of demarcating, efficiently solve the compatibility issue of concentrated feeder automation and demarcation switch, avoid accident interruption expanded range.
In order to solve the problem, the present invention is by the following technical solutions: a kind of concentrated feeder automation control method for troubleshooting of demarcating, can be used for the compatibility issue that concentrated feed line automatization system solves demarcation switch and concentrated feeder automation, it is characterized in that
Described concentrated feed line automatization system comprises:
At the output of each transformer station, transformer station's wire-outgoing breaker is set, and described each Substation control distribution line;
Connected by concentrated interconnection switch between different distribution lines, described concentrated interconnection switch is in open mode under normal conditions;
Distribution basic routing line is provided with some concentrated block switches, arranges a demarcation switch in the branch distribution circuit of each user, described concentrated block switch and demarcation switch are formed with power distribution automation main website respectively and communicate to connect;
Described method comprises following process:
The Operation system setting of power distribution automation main website: in the T time before exception handles starts, power distribution automation main website Real-Time Monitoring demarcation switch and concentrated block switch failure alarm signal, if in T time, monitor demarcation switch alarm signal, send " remote control combined floodgate " order to transformer station's wire-outgoing breaker, restore electricity; If in T time, do not receive demarcation switch alarm signal, start concentrated exception handles;
Fault section isolation: while phase fault occurs certain user, transformer station's wire-outgoing breaker protection act tripping operation, the demarcation switch tripping operation also locking of this user, realize the isolation of failed subs criber, whole concentrated block switches on the distribution wire at this user place detect that fault current sent stream information, demarcation switch and concentrated block switch fault alarm signal can will be delivered to power distribution automation main website simultaneously, and main station system generates event name;
Non-faulting region restores electricity: power distribution automation main website monitors this user demarcation switch fault alarm signal in T time after transforming plant protecting tripping operation; do not restart concentrated feeder automation exception handles; send " remote control combined floodgate " order directly to transformer station's wire-outgoing breaker, recover non-fault line and power.
Preferably, described T time is 30 seconds.
The present invention has the following advantages: performing step of the present invention is simple, the process to user's phase fault can not only be realized fast, and solve the compatibility issue of concentrated feeder automation and demarcation switch in process user phase fault process, avoid accident interruption expanded range, improve the fail safe of transmission line.

Embodiment
A kind of concentrated feeder automation control method for troubleshooting of demarcating provided by the invention, can be used for the compatibility issue that concentrated feed line automatization system solves demarcation switch and concentrated feeder automation, it is characterized in that,
Described concentrated feed line automatization system comprises:
At the output of each transformer station, transformer station's wire-outgoing breaker is set, and described each Substation control distribution line;
Connected by concentrated interconnection switch between different distribution lines, described concentrated interconnection switch is in open mode under normal conditions;
Distribution basic routing line is provided with some concentrated block switches, arranges a demarcation switch in the branch distribution circuit of each user, described concentrated block switch and demarcation switch are formed with power distribution automation main website respectively and communicate to connect;
As shown in Figure 1, a kind of concentrated feeder automation control method for troubleshooting of demarcating of the present invention comprises following process:
The Operation system setting of power distribution automation main website: in the T time before exception handles starts, power distribution automation main website Real-Time Monitoring demarcation switch failure alarm signal, if in T time, monitor demarcation switch alarm signal, send " remote control combined floodgate " order to transformer station's wire-outgoing breaker, restore electricity; If in T time, do not receive demarcation switch alarm signal, start concentrated exception handles;
Fault section isolation: while phase fault occurs certain user, transformer station's wire-outgoing breaker protection act tripping operation, the demarcation switch tripping operation also locking of this user, realize the isolation of failed subs criber, whole concentrated block switches on the distribution wire at this user place detect that fault current sent stream information, demarcation switch and concentrated block switch fault alarm signal can will be delivered to power distribution automation main website simultaneously, and main station system generates event name;
Non-faulting region restores electricity: power distribution automation main website monitors this user demarcation switch fault alarm signal in T time after transforming plant protecting tripping operation; do not restart concentrated feeder automation exception handles; send " remote control combined floodgate " order directly to transformer station's wire-outgoing breaker, recover non-fault line and power.
Fig. 2 is the line map of a kind of embodiment of the present invention, illustrates implementation result of the present invention below in conjunction with Fig. 1 and Fig. 2.
In fig. 2, circuit 1 adopts concentrated feeder automation pattern, and CB1 is circuit 1 transformer station outlet switch, and F001-F003 is circuit 1 concentrated block switch, FB001-FB003 is user demarcation switch on on-load switch type post, and circuit 1 and circuit 2 are formed by interconnection switch L1 and get in touch with.Suppose that phase fault occurs the F1 point being positioned at user 3, then concrete treatment step is:
