Abstract: A method of controlling a wind turbine having a rotor and a generator for producing power, the method comprising the steps of: obtaining an operational parameter, the operational parameter representing the loading experienced by the wind turbine due to a turbulence intensity acting on the rotor of the wind turbine; controlling the wind turbine in dependence on the operational parameter by altering at least one of a rotational speed setpoint of the rotor and a minimum pitch setpoint of a blade of the rotor; wherein the step of obtaining the operational parameter comprises: determining a rotor power produced by the rotor; and calculating a standard deviation of the rotor power over a period of time.

Abstract: A method of controlling a wind turbine, the method comprising monitoring a speed reference parameter of the wind turbine, and setting an overspeed threshold in dependence on the speed reference parameter, so that the overspeed threshold varies with the operational speed of the wind turbine. The invention also resides in a system that implements the method.
