Abstract :
According to mapping relationship of the relative internal efficiency of low pressure cylinder of condensing steam turbine and its affection, a mathematical model based on the Immune system´s wavelet network was established. It can be used for calculating the relative internal efficiency of low pressure cylinder of 300 MW steam turbine. The application of the model shows that the proposed method is featured by swiftness, high precision and good generalization ability, a new approach is provided for the diagnosis on line.
