Application of hybrid neural network to fault diagnosis for pumping stations

The shortage of expert system and multi layer back propagation neural network for the recognition of new faults is analyzed, and the mathematical model and structure of the neural network are studied. A hybrid neural network model utilizing both MLP and ATR1 is put forward so as to identify the fault modes effectively. Its application to fault diagnosis and state monitoring for a pump system shows that the hybrid neural network may recognize the fault modes in pump units reliably.
