Distribution network self-healing method based on peer-to-peer information interaction

Abstract

According to the distribution network self-healing method based on peer-to-peer information interaction provided by the invention, peer-to-peer communication between devices is carried out by adoptingGOOSE and other multicast protocols among all the devices in the system, respective electrical quantity information is interacted, the method does not depend on a communication master station, an FAcommunication network networking mode is adopted for communication, and the on-site stay wire wiring workload is reduced; when a fault occurs, the position of a fault point can be quickly and accurately judged through information subscribed and published by each other, fault removal and isolation are realized with fewer action times, and a self-healing power transfer line is reasonably selected for power transfer according to the load capacity of each incoming line, the load capacity of a fault line and an operation topological relation. The problem of uneven load caused by unreasonable transfer supply is avoided, and the adopted transfer supply strategy supports multi-contact selection and can adapt to dual-power-supply, multi-power-supply and petal type operation structures.

Description

technical field [0001] The invention relates to the technical field of power supply and distribution, in particular to a distribution network self-healing method based on peer-to-peer information interaction. Background technique [0002] With the rapid development of the urbanization process, the requirements for the reliability of the power supply of the power distribution system are constantly increasing. Reasonable power transfer, restore the power supply of the non-faulty section, and reduce the power outage area. At present, in the medium-voltage distribution network system, most of the fault self-healing systems used are centralized, that is, centralized data collection and strategy judgment, many on-site wiring, and heavy maintenance workload; and due to the complex structure of the distribution network system and the Diversified, unclear relationship between connection lines, etc., lead to the self-healing criterion cannot be generally applied, the power transfer i...

Problems solved by technology

[0003] In order to solve the problems of the prior art, the present invention provides a distribution network self-healing method based on peer-to-peer information interaction. The communication adopts a network networking mode, which reduces the workload of on-site cable connections; The subscribed and published information can quickly and accurately determine the location of the fault point, and realize fault removal and isolation with a small number of actions. Power transfer is carried out by more transfer lines, avoiding the problem of uneven load caused by unreasonable transfer
