Research on Smart Distributed Self-healing Control Based On the Peer-to-peer Communication Net

Abstract

Based on the analysis of the structure and function of the intelligent distribution unit, the goal of distribution network self-sealing and the processing procedure of the distribution self-healing, smart distributed self-healing control system which is based on the peer-to-peer communication nets is proposed in this paper. To solve the problem of the poor information interaction between terminals caused by the intelligent power distribution terminal and leapfrog trip when faults occurring, the system makes some references to the IEC61850's layering architecture pattern andoriented-object GOOSE model. By building the computing model intelligent distributed terminal unit and FA logic algorithm, the system could achieve the target of faultmonitoring, faultpositioning, fault isolation and the recovery of the non-fault area. Thepeer-to-peer communication model could guarantees the packets transmission's real-time and flexibility.By the use of the model and experiment of the distribution automation system,the distributed self-healing control achieves the effective control of the multi-point to multi-point connection between the smart distributed terminal unit, and also guarantees the veracity and reliability of fault location, fault isolation and fault recovery.
