Comparison of Methods for Voltage Sag Source Detection in Distribution System
电压暂降已经成为最受关注的电能质量问题之一.电压暂降源位置的确定对暂降故障检测、诊断及制订缓和措施十分必要,同时有利于区分暂降责任,协调缓解纠纷.对现有的基于无功功率变化、基于系统参量斜率、基于实部电流分量和基于距离阻抗继电器四种电压暂降源的定位方法进行了原理分析和仿真比较,对其进行了分类并讨论了各自特点,证实了基于距离阻抗继电器方法在暂降源方位判定上的准确性,并对该方法进一步研究提出了建议.
Voltage sag has been one of the most concerned problems of power quality. Identifying the location of the source of voltage sag is critically necessary for power-quality trouble-shooting, diagnosis and mitigation, and it is helpful to distinguish responsibilities and solve disputes caused by voltage sag. This paper analyzes and compares four existing location methods based on reactive power variation, slope of the system trajectory, real current component an…查看全部>>
