A wind turbine yawing slip fault diagnosis system and early warning method

Abstract

The application discloses a wind turbine yawing and slipping fault diagnosis system and early warning method, relates to the field of wind turbines, and aims at solving the problems of low judgment efficiency of the yawing and slipping fault caused by the mode of determining the yawing and slipping of the wind turbine by periodical visual observation or inspection and the problem of being unable to know the fault condition in time, and comprises a preliminary inspection judgment module, a comprehensive analysis module and a blade analysis module. The preliminary inspection judgment module is used for initially judging the working state of the wind turbine. The comprehensive analysis module is used for comprehensively analyzing the unit condition of the wind turbine. The blade analysis module is used for analyzing the blade condition of the wind turbine. Without any operation or generation of the wind wheel abnormal signal, the number of the wind turbine corresponding to the wind wheel abnormal signal is sent to a fault warning module. The fault warning module is used for displaying the number of the wind turbine corresponding to the wind turbine. Through comprehensive analysis of the wind turbine, timely and accurate judgment of the yawing and slipping fault of the wind turbine is realized.
