Distributed Feeder Automation Fault Information Interaction Method

Abstract

The invention provides an automated fault information interaction method of a distributed feeder. The automated fault information interaction method is implemented by feeder terminals with the functions of receiving and transmitting a fault information message, a fault information response message and a query fault information message, and comprises the steps as follows: various feeder terminals detect a fault in real time; the feeder terminal of detecting the fault periodically transmits the fault information message to the adjacent feeder terminal as a source end; the adjacent feeder terminal transmits the fault information response message to the source end after receiving the fault information message; and the feeder terminal of starting fault judgment inspects that the fault information of the adjacent feeder terminal is collected completely, and then enters a fault judgment algorithm to determine a fault point. The problems of long fault isolation time, large network traffic and the like in an existing automated fault information interaction method of the distributed feeder can be effectively solved through increasing of the fault interaction message type and mutual cooperation of multiple interaction messages.

Description

technical field [0001] The invention relates to a fault information interaction method in a distributed feeder automation system in power system automation. Background technique [0002] The distributed feeder automation of the distribution network system does not require the participation of the main station and the substation, and completes fault processing according to its own and adjacent fault information. Distributed feeder automation is divided into channelless distributed feeder automation and channel distribution according to whether communication is required for fault processing. In the case of non-channel distributed feeder automation, only the fault information detected by its own power distribution terminal is used for fault judgment; channel distributed feeder automation uses the mutual communication and timing cooperation between power distribution terminals to complete the fault when processing faults. Processing, also known as intelligent distributed feeder ...
