Abstract
The present invention relates to a method of controlling an idling wind turbine in which wind condition data and wind turbine position data are collected by a sensor system, a control system computes an optimal pitch angle for a rotor blade of the wind turbine, and a pitching system continuously turns the rotor blades in the same direction in multiples of 360 degrees. The present invention further relates to a wind turbine with a sensor system including a wind sensor that measures wind condition data in the vicinity of the wind turbine, and a control system including a computer that executes a control algorithm and processes sensor input from the sensor system to compute an optimal pitch angle value for a rotor blade on the hub. This allows pitching the rotor blade into angle in which the mechanical loads of that rotor blade are reduced to a minimum when idling.
