水电机组故障诊断中的推理策略

Reasoning engine of the fault diagnosis system database for hydroelectric generating units

在水轮发电机组监测与故障诊断专家系统中 ,推理机的设计是专家系统的核心 .针对水电机组的特点 ,讨论了知识的表达方式、专家系统推理机推理策略的实现 ,并讨论了规则可信度的计算 .该推理方法用于白莲河水电站监测与故障诊断系统中 ,成功地对机组的故障原因进行了推理 ,证明该推理方法是可行的 。

Considering the characteristics of hydroelectric generating units, we discussed the representation of expert knowledge, the implement of reasoning machine and the calculation of certainty factor in the state monitoring and fault diagnose expert system for hydroelectric generating units. This system has been successfully applied in state monitoring and fault diagnosis system in Balianhe hydropower station.
