Wind turbine generator blade fault diagnosis system and method

The invention discloses a wind turbine generator blade fault diagnosis system and method. The problems that in the prior art, a blade audio fault diagnosis method is low in efficiency, and blade fault type judgment cannot be achieved are solved. According to the method, the health of the blade is monitored by using the blade sweeping pneumatic noise, the fault judgment of the blade of the wind turbine generator based on the audio is realized, fault information is fed back to field operation and maintenance personnel, and field troubleshooting and maintenance are guided. 本发明公开了一种风电机组叶片故障诊断系统与方法。为了克服现有技术中叶片音频故障诊断方法效率低，且无法实现叶片故障类型判断问题;本发明利用叶片扫风气动噪声对叶片及进行健康监测，实现基于音频的风电机组叶片故障判断，给现场运维人员反馈故障信息，指导现场排查与检修。
