Realization of Fuzzy Expert System for Fault Diagnosis

For the engineering problems of fault diagnosis in multiheterogeneous power system, the paper proposes a concrete realization framework of fault diagnosis. Communication and data structure configured independently is introduced to achieve the seamlessly connection of multiple protocol communications in power system and to solve the problem of receiving unified analysis and storage data between top equipment and underlying heterogeneous devices. Under the fault diagnosis framework, a comprehensive diagnosis is designed and implemented using fuzzy expert system and other fault data process ing. Power system can achieve a variety of equipment, parameters and fault criterion standardization of information based on the xml system configuration information describing. A fault diagnosis algorithm is proposed to realize fault location of all e quipment in the system. The diagnosis example results show that the system has high efficiency, credibility and good reason ing, able to meet the requirements of power system fault diagnosis.
