Fuzzy Neural Network-based Fault Diagnosis for Thermal Control System of Thermal Power Plant Based on Fuzzy Neural Network
The operation of thermal control systems in thermal power plants is achieved through the cooperation of numer-ous components,making fault diagnosis difficult.Therefore,a fuzzy neural network-based fault diagnosis method was proposed.From the perspective of composition and operational attributes of the thermal control system in thermal power plants,a fuzzy neural network model for thermal control system in thermal power plants was constructed by combining fuzzy control with a 5-layer equivalent BP neural network.Forward propagation of operating state variables and back prop-agation of errors were carried out within the model to achieve fault diagnosis.The test results indicate that the designed method has achieved accurate diagnosis of the fault states of seven different types of thermal control systems in thermal power plants.
