大型抽水蓄能机组运行稳定性故障的自动诊断专家系统

专家系统已被广泛地用于机械设备的故障诊断中，但是把设备监测系统的输出数据作为诊断专家系统的输入数据，将二者有机地结合起来形成自动诊断专家系统，并用于大型水力发电设备的监测诊断中在国内很少见到应用。本文介绍了自动诊断专家系统的一般原理及其在广州抽水蓄能电站状态监测与故障诊断系统中的具体实现，并结合实例作了介绍。该自动诊断专家系统包容了监测系统，并且能方便地同电厂的自动化控制系统结合成一体，它的应用将大大提高发电厂的自动化程度。

Automatic Diagnostic Expert System for the Stability of Large Scale Pumped Storage Power Generator Sets

Expert system has been widely apllied to the machinery diagnosis, but to take the output data of the machinery monitoring as the input data of the diagnosis expert system, combining these two respects as one whole system——automatic diagnosis system, and to use this system in the field of large scale pumped storage power generator sets, this is the first time to be realized in china. This paper introduces the basic principle of the system and the realization in the Guangzhou pumped storage power generator monitoring and diagnosis system, at the same time, an example of the diagnosing result has been given. The automatic diagnosis expert system including the monitoring system, can also be brought conveniently into the automatic control system of the station. The application of this system will greatly improve the automation of power station.
