基于广域测量的故障区段定位方法
Positioning Method for Fault Section Based on Wide Area Measurement
摘要
Abstract
Due to the wide adoption of non-effective grounding mode for neutral point of power distribution network and weak characteristic quantities of faults such as single-phase grounding, there are short of effective and reliable methods for fault line selection and fault positioning.Therefore, this paper analyzes characteristic of zero sequence current in the overall process of fault, defines standard deviation degree of zero sequence current of adjacent detection points and presents a positioning method for fault section based on wide area measurement system(WAMS).By combining accuracy and rapidity of collecting data under the WAMS, it uses standard deviation degree of zero sequence current wave in the overall process of fault happening and action of the compensation device to locate the fault section.Finally, simulation on PSCAD/EMTDC verifies the feasibility and reliability of the proposed method.关键词
