Expert system on fault diag-nosis based on neural network for hydropower units

With fault diagnosis of turbine generator unit vibration as the research object,the expert system based on neural network and in combination with the real machine test on Yanguoxia hydropower plant is presented in this paper.By analysis of these experimental data,the conclusion is that it is effective to process fault diagnosis of turbine generator unit vibration with neural network expert system.The process of test investigation and analysis of diagnosis with designed software are also presented in this paper.
