摘要：针对变电站高压电气设备状态检测和故障诊断的问题，提出了基于数据采集与监视控制系统（SCADA/EMS）的变电设备故障诊断专家系统的整体设计方案。将变电设备故障诊断专家系统集成为SCADA/EMS系统中的一部分，实现了变电站作为整体进行分布式在线监测和故障诊断的功能。研究结果表明，该方案可充分利用SCADA/EMS原有的网络平台和设备状态监控信息，减少了变电站变电设备在线监测系统建设的网络和测点投资，适应于变电站综合自动化和无人值守的发展要求。

Abstract: Aiming at state detection and fault diagnosis of high voltage electrical equipments in power substation, a scheme of an expert system based on supervisory control and data acquisition/energy management system(SCADA/EMS) for fault diagnosis of electrical equipment was proposed. The power substation was considered as a whole and the expert system was integrated into the SCADA/EMS as one of its subfunction modules. The research results indicate that the existent communication network and state information of electrical equipments in SCADA/EMS can be used adequately, which will reduce the expense on building communication network and measure nodes for online monitoring system, and meet the needs of integrated substation automation and unattended substation mode.
Key words: power equipment; fault diagnosis; expert system; supervisory control and data acquisition/energy management system(SCADA/EMS)
