  • Pitch drive controller for a wind turbine, pitch drive control device, and method for controlling a pitch drive controller
    Patent number: 12188449
    Abstract: A pitch drive controller for a wind turbine having a plurality of rotor blades fixed on a rotor hub for rotational adjustment of the rotor blades on the rotor hub by an electric motor includes a pitch drive control device for each of the rotor blades. The pitch drive control device is in each case configured to actuate a pitch drive motor. The pitch drive control device has in each case an electronic actuation unit for the respective pitch drive motor, a control output to the respective pitch drive motor and a computing unit with a processor configured to operate the respective pitch drive control device. The drive control device has in each case a local communication connection and is connected or connectable to the other pitch drive control devices of the wind turbine in a cross-communication via the local communication connection.
