Intelligent power distribution network load transferring optimal path selection method based on Peer to Peer communication

Abstract

The invention discloses an intelligent power distribution network load transferring optimal path selection method based on Peer to Peer communication. The intelligent power distribution network load transferring optimal path selection method based on Peer to Peer communication includes the steps: 1) an intelligent terminal performs periodical routing inspection on the line and determines whether the line is operating normally, and if the line is operating normally, the terminal continues self-inspection, and if the line is not operating normally, entering the step 2; 2) the intelligent terminal performs fault positioning and fault identification to complete fault clearance, and then fault isolation is successes, and then entering the step 3; 3) entering the fault transferring program, according to the information of the voltage at a transferrable bus contact switch and the information of the current before the fault of the fault point, making a judgment on a plurality of transferring paths to obtain the optimal load transferring path; and 4) the program is ended. The intelligent power distribution network load transferring optimal path selection method based on Peer to Peer communication can automatically perform optimal load transferring on the power-loss load while the scheduler does not need selecting the transferring path according to experience tediously, so that the workload of the scheduler can be reduced greatly and the work efficiency and accuracy can be improved.

Description

technical field [0001] The invention relates to the field of power distribution, in particular to an optimal path selection method for load transfer of an intelligent power distribution network based on peer-to-peer communication. Background technique [0002] With the rapid development of low-voltage distribution network in my country, the reliability of power supply directly affects the production and life of society. In the distribution network, the ring network wiring method is the most typical type of backup wiring. At the same time, the wiring method of dual power supply and multi-power supply power supply in the distribution network is becoming more and more common. When a busbar, switch or ring network cabinet of the distribution network needs to be repaired or a fault occurs somewhere, in addition to isolating the corresponding fault area, the load transfer should also be carried out in the power loss area. It is connected to other busbars or feeders, so as to real...

Problems solved by technology

[0003] There are a lot of electrical equipment in the distribution network, the wiring forms are becoming more and more complex, and the number of transfer paths for a single feeder is also significantly increased, thus forming a huge power supply network in which many lines can reverse each other, and a fault often occurs The problem that a line can be reversed by multiple lines

Aiming at the multi-path transfer problem of the above-mentioned lines, although dispatchers can make judgments and choices by calculating all possible load tra
