基于零序电流相位法的配电网故障定位

该文根据零序电流相位法故障定位的原理，简单介绍了其定段方法。对整体系统的构成及实现进行了概述，其中零序电流的采集，主要是通过GPS秒脉冲进行同步采样，并建立了GPS时间与电流相位的关系；然后将得到的时间相位信息经无线通信模块实现数据的传输。采用零序电流相位进行故障定位，直接利用故障时产生的电流信号，避免了外加信号对系统运行的附加影响，增强了其可靠性；另外，基于MATLAB的仿真模型实验也证明了该方法的可行性。

Distribution Network Fault Location Based on Zero-sequence Current Phase

According to the zero sequence current phase fault location’s principle,the article introduced the location method and summarized the overall system.It used GPS for synchronous sampling of the zero sequence current,and established the relationships between GPS time and current phase.Then transfer the phase information by the wireless communication module.This location method used the current signal when is generated fault,so it avoid the impact of the applied signal for the system and enhanced reliability.Additionally,the simulation experiments based on MATLAB could also prove the method’s feasibility.
