摘要
针对配电网继电保护通信网络同步精度低、故障定位不准确等问题,引入时间序列,开展配电网继电保护通信网络仿真研究。结合时间序列,构建配电网继电保护模型;利用正序故障分量,实现配电网继电保护;设计配电网继电保护通信网络同步结构,实现配电网继电保护同步通信。通过仿真实验得出,新的方法应用下可以准确定位故障位置,并实现通信同步。
In view of the problems of low synchronization accuracy and inaccurate fault positio-ning of distribution nctwork,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.
