摘要
针对目前电站故障诊断专家系统均以周期触发诊断为主,提出了一种基于报警状态触发的自诊断专家系统。通过故障机理分析获取故障类型与主要征兆,采用层次分析法得出具体的诊断推理策略,基于故障诊断软件模块实现系统功能,对专家系统在动态故障诊断领域中的应用具有参考价值。
In view of existing periodic triggering diagnosis as the fault-shooting expert system in power plant, a fault-located self-diagnosis expert system based on the alarm triggering has been put forward. Based on different types of faults and their symptoms obtained from analysis on faults＇ mechanism, a reasonable diagnosis pattern has been established by analytic hierarchy process. Finally a whole system has been composed by different modules of software. The expert system may serve as a reference for on-line faultdiagnosis of power plants.
