The Research on Condition Monitoring and Fault Diagnosis Method of Wind Power Spindle Bearing

Abstract

With the continuous and substantial increase in the demand for wind power generation in China, the development of wind power generation units tends to be large-scale, intelligent and efficient. Besides, the working environment of spindle bearings is relatively bad and the failure rate is relatively high. Therefore, it is necessary to conduct state monitoring and fault diagnosis for wind power generation units. This paper first introduces the bearing system of wind turbine, then expounds the common faults of wind turbine spindle bearing, and carries out relevant research. According to the fault types, this paper investigates and combs the condition monitoring and fault diagnosis methods of spindle bearing. Finally, the author proposing a new condition monitoring method, which solves the vacancy of condition monitoring method based on strain.
