Study of Fault Diagnosis Wind Turbine Generator System

To find the fault of the wind turbine generator system early and to use proper measure to solve the fault in time and so to increase the operation effciency,the possible faults of the wind turbine generator system were analyzed.The fault diagnosis method of the wind turbine generator system was studied.The possible faults and the diagnosis method which can be used in the several main parts of the wind turbine generator system were discussed.The fault phenomenon and the diagnosis method were simulated and analyzed.The conclusions are:Temperature field analysis can be used to analyze the heat deform of the gear,neural network and wavelet analysis to analyze the fault of the converter and magnet field analysis can be used to analyze the fault of generator.
