摘要
以模糊理论为基础,结合水轮发电机组的结构设计、运行工况、现场运行人员和专家的经验,分析了故障与征兆之间的模糊关系,形成了水轮发电机组诊断规则,建立了水轮发电机组模糊诊断自适应修正数学模型,并用某水电厂具体故障实例加以分析、诊断、验证,结果证明了该数学模型的合理性和适用性。
On the basis of fuzzy set theory and in combination with the structure and performance of hydropower generating units, and the experts' experiences, the paper analyzes the fuzzy relationship between the faults and their omens. The rules for diagnosis of hydropower generating units are developed, and a self-adaptive fault diagnosis model is established for hydropower generating units. The mathematical model is proved to be rational and suitable by a fault diagnosis example of a hydropower station.
