The safety, stability and economic is the main target of the power system operation. In the modern power system, the computer system provides alarm and fault information collection functions, which improves systematic level of the system operation, and provides technological specifications to gain fault information. On the other hand, under the urgent and fault condition, it will be more difficult for operators to filter information and recognize fault when large volume of information pouring in. With the continuous improving of dispatching automatization system performance, and the popularization and application of relay protection management information system, the volume which dispatching centre received has increased more largely than ever before. When there is fault in power grid, it happens frequently that dispatcher needs to face several times or even hundreds of times fault related information than normal operation, also, because of lack of unified integration of data processing and analysis tools , this large pouring information will cause great inconvenience to the dispatcher who deals with the accident. In order to deal with the accident, dispatcher also needs to find and retrieve quickly for lots of relevant accident treatment information. A set of effective fault treatment intelligent decision system is needed to implement automatic rapid identification, isolation and restoration for power grid fault.This essay analyses various power grid fault diagnosis theory, extracts the previous research findings and deficiency, and suggests some key technology points for implementation of accident treatment intelligent assistant decision-making system based on the dispatch automatic system, such as intelligent preventing misoperation system,information flow control etc, and defines basis structure of the system and various function needs. This system provide dispatcher with accident anticipation and simulated training platform against accidents, and other functions when the power grid is operating normally. When fault happens in the power system, it automatically provide fault point,fault type,power failure area,important users involved and other information, and according to the power system running mode and network topology, it intelligently or manually creates recovery scheme, and provides effective and comprehensive means to prevent the misoperation, which ensures the safety and stability of the power system.
