| Abstract: | Wind turbines are subject to fault because of bad working conditions in the natural environment.A condition monitoring and fault diagnosis system can be used to monitor its operating condition and diagnose the possible fault in real time.The historical and present researches of wind turbine condition monitoring and fault diagnosis techniques are reviewed in the paper,and its basic structure is illustrated.The frequently-used condition monitoring technique and its main measurement parameters are analyzed here to put forward the common faults,and the failure mechanism.At the end,the paper discusses several fault diagnosis methods fit for the wind turbine. |
