摘　　要：针对电力系统多异构设备故障诊断工程化不高的问题,提出一种具体的故障诊断实现框架。采用通信方式和数据结构独立配置的方法,实现电力系统多种协议通信的无缝连接,解决了底层异构设备数据在顶层设备中的接收、分析和存储难以统一的问题;在故障诊断框架下,设计并实现模糊专家系统和其他故障数据处理综合诊断;研究了基于xml的系统配置信息描述,能够实现电力系统中各种设备、参数和故障判断准则等信息的标准化;同时提出了一种故障诊断算法,实现系统各设备的故障定位。诊断实例结果表明,系统推理效率高,可信度好,能够满足电力系统故障诊断要求。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.
