A New Fault Diagnosis Approach of Power Grid Based on Cooperative Expert System and Multi-agent Technology
Zaihua Li · Proceedings of the CSEE · 2006
A new fault diagnosis approach is presented which is based on multi-agent technology and the cooperative expert system. In the proposed approach, the unit of the cooperative expert system is designed according to the modified agent models and the real-time expert system, and the structure of the whole system is also presented. The whole system is composed of seven sub-systems which are capable of finishing different tasks such as fast diagnosis of complex fault, handling distorted and uncertain information and offering the operational advices et al. The main point of this system is the fact that it is able to overcome the deficiency of the common expert system for the diagnosis of the complex and correlative faults. The cooperation in function can assist in enhancing the reasoning ability, and the regional cooperation can assist in diagnosing the fault expanding from one district to another. The simulation results show that the system works successfully and efficiently in the case of practical power grid and fits for the realization of real-time fault diagnosis.
