Abstract:
1. A method of operating a wind turbine in response to an over-temperature condition on a wind turbine control motor, the wind turbine including a wind turbine generator, a converter and at least one rotor blade, the method comprising: monitoring a temperature of at least one wind turbine control motor; monitoring a wind speed for the wind turbine; controlling operation of the wind turbine according to a normal wind turbine control function when the temperature of the at least one wind turbine control motor is below a first predetermined temperature; modifying the wind turbine control function for continuing operation of the wind turbine under an operating scheme for the at least one wind turbine control motor when the temperature of the at least one wind turbine motor exceeds the first predetermined temperature; and restoring normal operation of the wind turbine according to the wind turbine control function when the temperature of the at least one wind turbine motor falls below the first predetermined temperature.
