Multi-source D-S evidence information fusion and fault traveling wave analysis of distribution network

Abstract: Compared with single information source fault location, multi-source information fusion can make full use of power system automation equipment, gather more information together, and greatly improve the accuracy of fault location. This chapter analyzes the relevant theories of multi-source information fusion technology and D-S evidence theory, analyzes various characteristics of traveling waves after faults occur, and provides theoretical support for fault location and configuration research of traveling wave devices for reference by peers.
