摘要
Abstract
The most common fault in distribution networks is grounding fault.To accurately detect and isolate grounding fault lines and restore power supply as soon as possible,a single-phase grounding fault location and recovery method based on distribution switch monitoring terminal(FTU)is proposed.Using the wavelet packet transform transient line selection and phase current transient characteristic line selection technology of FTUs at each node of the distribution network,combined with the fault path adaptive processing control strategy,and coordinating the delay closing logic of the first switch,the multi branch distribution network fault localization and automatic isolation recovery can be achieved.The proposed method can quickly select faulty lines and isolate faulty sections,which is conducive to the rapid elimination of faults and improves the safety and reliability of system operation.关键词
