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.
