基于电压偏差向量2-范数的主动配电网故障定位新方法
Fault Location Method of Active Distribution Networks Based on 2-norm of Voltage Deviation Vectors
摘要
Abstract
With the increasing interconnection of distributed generators in distribution networks,some of the existing fault location algorithms may fail.A fault location method based on the minimum 2-norm of voltage deviation vectors is proposed. Firstly,the fault current is injected into each bus of the distribution network model to calculate the voltage variation of the power source.Secondly,the difference between measured voltage variation and calculated voltage variation is analyzed,and the fault current injected bus corresponding to the minimum difference is searched and determined as the first bus of the fault section.Finally,the other bus of the fault section is determined according to the variation trend.An IEEE 34-bus system is chosen to verify the algorithm,the results showing that the algorithm has clear physical meaning,simple calculation process and good fault location accuracy.The more distributed generation is connected,the better fault location accuracy will be.关键词
