Electrical yaw drive for a wind turbine, wind turbine and method for operating a wind turbine

摘要

An electrical yaw drive for a wind turbine is described, wherein the wind turbine includes a wind turbine nacelle and a wind turbine tower. The electrical yaw drive has an asynchronous motor, an excitation capacitor bank and dump loads, wherein the excitation capacitor bank and the dump loads are electrically connectable to windings of the asynchronous motor. Furthermore, a wind turbine with such an electrical yaw drive and a method for operating such a wind turbine are described.
