Abstract (English): II is difficult to accurately locate fault in a distribution network by one-terminal or two-terminal traveling wave method. So, a multi-terminal traveling wave fault location method was proposed. In this method, a self-adaptive strategy for traveling wave detection based on Park's transformation was made. The theory of multi-terminal traveling wave fault location method was established on the basis of analyzing the defects of the two-terminal traveling wave method. The delected arrival time of traveling wave on the terminal of distribution lines was used in fault location. The proposed method avoids the difficulty in recognizing reflect waves, and is independent of different fault types, fault inception angles and different fault resistances. Various fault cases in a distribution network were simulated by PSCAD/EMTDC and MATLAB. The results verify that the proposed method can locate fault point quickly and accurately, showing the method reliable and suitable. [ABSTRACT FROM AUTHOR]
Abstract (Chinese): 单端和双端行波定位方法都很难准确定位配电网故障,因此提出一种采用多端行波的配电网故 障定位方法. 首先给出基于Park 变换的自适应行波检测策略,在分析双端行波定位缺陷的基础上,根据检测 到的行波到达各配电线路末端的时间,给出多端行波故障定位的原理. 该方法克服了由于配电线路结构复杂 所造成的反射波识别困难,而且不受故障类型、故障初始相角和接地电阻大小的影响. 采用PSCAD / EMTDC 仿真软件和MATLAB 软件对不同的故障工况进行仿真,仿真结果表明,本文方法能够快速准确地定位故障 点,从而证实了该方法的有效性和可靠性.
