System and method for detecting pitch bearing damage in a wind turbine

Patent Pan, Di; Hao, Liwei; He, Lijun; ...

The present disclosure is directed to a system and method for detecting damage of a pitch bearing of a wind turbine. The pitch bearing is part of a pitch drive system having a plurality of pitch drive motors. The method includes measuring at least one electrical signal of the pitch drive system. The method also includes processing the electrical signal(s) of the pitch drive system and comparing the electrical signals of the pitch drive system with a baseline threshold. Thus, the method also includes determining whether damage is present in the pitch bearing based, at least in part, on themore » « less

System and method for monitoring a wind turbine pitch bearing

Patent He, Lijun; Hao, Liwei; Mihok, John Joseph

A system and method for monitoring a pitch system of a wind turbine includes monitoring, via one or more first sensors, at least one electrical condition of the pitch system. The method also includes monitoring, via one or more second sensors, at least one mechanical condition of the pitch system. Further, the method includes receiving, via a controller communicatively coupled to the one or more first and second sensors, sensor signals representing the at least one electrical condition and the at least one mechanical condition of the pitch system. Thus, the method includes determining, via the controller, a bearing conditionmore » « less
