In the proposed approach, the unit of the 域故障进行诊断。通过实例对系统的工作流程进行了说明并 cooperative expert system is designed according to the 验证了协同诊断方法的正确、有效，该方法适合用于实时故 modified agent models and the real-time expert system, and the 障诊断系统。 structure of the whole system is also presented. The whole system is composed of seven sub-systems which are capable of 关键词：电力系统；故障诊断；协同式专家系统；多智能体 finishing different tasks such as fast diagnosis of complex fault, 0 引言 handling distorted and uncertain information and offering the operational advices et al. The main point of this system is the 电力系统规模的不断增大以及复杂性的不断 fact that it is able to overcome the deficiency of the common 提高，致使SCADA/EMS采集到各站(厂) 的 时数据 expert system for the diagnosis of the complex and correlative 规模也越来越大，远远超出了调度员的处理能力， faults.
