Abstract
In this paper, the fault diagnosis technology of power system is studied, and it is divided into three types based on mathematical model, statistical method and artificial intelligence. Then, the problems existing in its application are analyzed, including the inconsistency of equipment data processing methods, the limitations of data acquisition methods and the uneven distribution of fault data. Finally, three optimization methods, multi-source data fusion, data intelligent optimization and fault diagnosis algorithm optimization, are proposed to improve the accuracy and reliability of power system fault diagnosis. The research of this paper provides a strong guarantee for the stable operation of power system, and provides guidance for the development direction of power system fault diagnosis technology.
