CONTROL METHOD FOR A WIND TURBINE

摘要

The invention relates to a method of controlling a wind turbine having a rotor with pitchable wind turbine blades and a generator for producing power, where a control signal for a controllable parameter of the wind turbine is determined, and an operational parameter representing a loading on the wind turbine exerted by the wind is estimated at time intervals. From this is determined a variation parameter reflecting the variation of the operational parameter over time. The wind turbine is then controlled according to the control signal only if the variation parameter is below an alert threshold, and otherwise according to a modified control strategy.
