Research on Fault Location Method of Distribution Network from Multi-Source Wide Area

Distribution network is an important infrastructure to ensure national economic development and improve residents' living standards. It has a wide distribution range, bad operating environment and frequent random failures, which are easy to cause personal and equipment safety accidents and directly lead to power failure of users. Accurate and reliable distribution network fault location technology is the key to speed up fault recovery and reduce outage time. In recent years, the development and application of distribution network synchronous measuring device and its wide area measuring system provide advanced technical means to improve the level of distribution network fault location. This paper studies the fault location method of distribution network based on multi-source wide area synchronous information. Based on the principle and method of fault location based on different types of measurement information such as time domain and traveling wave, the problem of distribution network fault location in complex scenarios is solved.
