一种含分布式电源的电网故障判断方法

A Study on the Diagnostic Method for Grid Faults with a Distributed Generator

提出一种含分布式电源的电网故障判断方法,该方法在检测传统电压幅值跌落的基础上,计算其电压跌落速率以保证故障检测的准确性,减少误判和漏判。并通过仿真实验对此方法进行分析,验证了其有效性和灵敏度。

This paper presents a diagnostic method for grid faults with a distributed generator,which calculates the voltage drop rate to ensure the accuracy of the fault detection as well as reducing wrong diagnoses and missing ones based on the detection of the traditional voltage amplitude drop. Simulation experiments have verified its effectiveness and sensitivity.
