摘要
针对配电网单相接地故障定位难的问题,阐述了传统信号注入法的基本原理,提出了改进信号注入法,建立了matlab/simulink仿真模型。通过Matlab仿真实例验证,该方法有效可行,实现了在线故障定位,有效地缩短了停电时间和减少停电次数,提高了配电网供电质量稳定性。
Abstract ： Aiming at the duces the basic principle difficult location of single - phase grounding fault for distribution network, this paper intro- of traditional signal injection, proposes the improved signal injection and establishes mat- lab/simulink simulation model. Verified by the Matlab simulation example, the method is proved feasible, which realizes online fault location, effectively shortens outrage time and reduces outrage frequency and enhances the sta- bility of power supply for distribution network.
