Embodiment Construction

[0084] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0085] Such as figure 1 As shown, a self-healing control method for smart distribution network based on a peer-to-peer communication network includes the following steps:

[0086] 1) The intelligent terminal unit (hereinafter referred to as ITU) periodically checks whether the line is normal. If it is normal, each ITU performs a periodic self-check, and the ITU checks the communication with the neighbor. If only one side of the neighbor cannot communicate, then Taking the neighbor's neighbor as its own new neighbor terminal, each terminal updates the network topology information; if it is not normal, go to step 2).

[0087] 2) When a fault occurs on the line, each terminal will judge whether the network protection is started, judge that the line is in an abnormal state according to the preset fault current threshold, and further check whether there is ...

Abstract

The invention discloses an intelligent power distribution network self-healing control method based on a peer-to-peer communication network. The intelligent power distribution network self-healing control method comprises the following steps of 1) enabling an intelligent feeder line terminal to periodically detect whether a line is normal or not, if the line is normal, enabling each intelligent feeder line terminal to execute periodical self detection, and if the line is abnormal, beginning to implement a step 2); 2) performing network protection starting judgment, if a starting criterion is not satisfied, finishing a program; and if the starting criterion is satisfied, activating a network protection program and beginning to implement a step 3); 3) performing a fault positioning program, judging whether a fault isolation mark is already set or not, if not, beginning to implement a step 4), and if so, beginning to implement a step 5); 4) performing a fault isolating program; 5) performing a primary reclosure program, judging whether reclosure is successful or not, if not, beginning to implement a step 6), and if so, beginning to implement a step 7); 6) performing a load transferring program; 7) performing a mark position reset program; and 8) completing the program. By adoption of the intelligent power distribution network self-healing control method, various kinds of potential hidden dangers can be found in time, prevented and isolated, faults can be repaired automatically, and power supply can be recovered rapidly.

Description

technical field [0001] The invention relates to the field of intelligent power distribution, in particular to a self-healing control method for an intelligent distribution network based on a peer-to-peer communication network. Background technique [0002] Smart distribution network self-healing control is the core technology to solve the key problems of low equipment utilization, low power supply reliability, and high line loss rate that have existed in my country's distribution network for a long time. It is an inevitable choice for the development of modern power grid technology. The earliest self-healing control in the power distribution system is the Feeder Automation (FA) technology, that is, the automation of the feeder line from the outgoing line of the substation to the user's electrical equipment. The core content of feeder automation technology is fault detection, fault isolation, load transfer and power supply recovery control of distribution network under accide...
