Construction of Expert System for Relay Protection in Power System

Ren Lachun

Abstract

To solve the problem of incompleteness and uncertainty of information in relay protection in power system,expert system of relay protection in power system is constructed in the paper.The construction of the expert system is mainly discussed.Its structure,inference rules and data acquisition are introduced.It can well solve kinds of faults problems in relay protection in power system.And it can also improve the accuracy of fault diagnosis to ensure the reliable operation of the power system.
