Research on distribution network fault zone location method based on improved matrix algorithm

In recent years, the scale of distribution networks has gradually expanded, and how to accurately determine distribution network faults from complex distribution networks is an important research direction in this field. The purpose of distribution network fault location is to discover faults and find the specific location of faults by suitable data analysis techniques. In this study, an improved matrix algorithm considering the causal relationship between "feeder segment state" and "switch node alarm" is proposed for interphase short circuit fault. The algorithm is able to locate faults quickly and accurately in both open-loop and closed-loop states of power distribution.The example of "a complex distribution network with single power supply and multiple T connections" shows that the improved matrix algorithm has good adaptability, accuracy, effectiveness and real-time.
