A New Detection Approach for Single-Phase Arc Grounding Fault of Distribution Mixed Feeders
摘要
Abstract
The transient quanlity is the most significant features when a fault occurs.But its short duration makes it difficult to de-tect the fault.Because of the transient zero sequence current contains a large number of high harmonic,which up to a cycle dura-tion,the paper presents a novel algorithm for single phase arc grounding fault location of distribution network.The Habedank arc modle is built.According to analyse the spectral characteristics of the transient zero-sequence current,the feature band is found.The amplitude and direction of transient zero-sequence current within the feature band is filtrated to detect the arc grounding fault.Simulation results demonstrate that the proposed algorithm is fast and accurate anti-jamming of the good characteristic.关键词
