APPLICATION OF EXTENDED Petri NETWORK INTO FAULT DIAGNOSIS OF THERMAL POWER UNITS
摘要
针对火电机组存在的设备故障
提出一种加权模糊Petri网的火电机组故障诊断模型
同时应用一种反向推理算法
对加热器的水位调节系统故障诊断进行建模、仿真。实践证明
该方法能够直观图形化地分析加热器的水位调节系统故障原因和故障置信度
可为火电机组安全运行提供有效保障。
Abstract
Directing against the equipment faults existing on thermal power units
a fault dignosis model of thermal power units by means of weighted fuzzy Petri network has been put forward
at the same time
modelling and emulation of fault diagnosis in water-level regulating system of the heater being carried out by using a reverse reasoning algorithm.Practice proves that the said method can directly and graphycally analyse the causes and confidence of fault occurred in water-level regulating system of the heater.
