摘 要:
在对配电网单相接地故障零序电流分析的基础上,提出了基于暂态分量的配电网单相接地故障测距方法,利用小波包重构系数形成各频段的能量值,构造出测距的特征向量,并引入支持向量机映射该特征向量与故障距离之间的对应关系。仿真结果证明该算法是有效的。[著者文摘]

Study on Fault Location by Transient Component for Single - Phase to Ground Fault in Distribution Networks
Wang Yansong (China University of Petroleum)
Abstract:
A novel method of fault location was presented based on transient component for singlephase to ground fault in distribution networks. By analyzing free oscillation frequency ineluded in the zero- sequence current of fault line head and utilizing energy values resulted from wavelet package reconfiguration coefficient, it constitutes characteristic vector of fault location and then maps correlation between the characteristic vector and fault distance. Simulations show that the novel algorithm is effective.[著者文摘]
