Abstract:
The present invention relates to a method and control system comprising at least one cable temperature sensor for measuring cable temperature values for at least one power collection cable (50, 55) connected to a wind turbine (20) and a controller (110) arranged to generate and output an overrating control signal to the wind turbine (20). The output overrating control signal sets an amount by which the power output of the wind turbine (20) is to be overrated. It is determined whether the measured cable temperature values exceed a temperature set point and modifying the overrating control signal to reduce the amount of overrating if the temperature set point is exceeded.
