Abstract
In view of the problems of low synchronization accuracy and inaccurate fault positio-ning of distribution network,time series is introduced to carry out the simulation research of distribution network relay protection communication network.Based on the time series,con-struct the relay protection model of the distribution network and design the communication net-work synchronous structure of the distribution network relay protection.Through the simula-tion experiment,the new method can accurately locate the fault position and realize the commu-nication synchronization.
