Fremgangsmåde til styring af driften af en vindmølle

摘要

The invention relates to a method to control the operation of a wind turbine above a certain wind speed threshold value. The invention even relates to a wind turbine, which is prepared and designed to execute this method. Electrical output power of the wind turbine is produced by rotating blades of the wind turbine. The produced output power is fed in a grid, which is connected with the wind turbine. The wind turbine is controlled by a first control loop and by a second control loop. The wind speed is determined and is compared with a certain predefined wind speed threshold value. Wind turbulences are determined and are compared with a certain predefined wind turbulence threshold value. The first control loop and the second control loop are activated if the wind speed reaches or exceeds the wind speed threshold value. The activated first control loop controls the output power in dependency of the wind speed. The activated second control loop controls the rotational speed of the rotating blades in dependency of the wind turbulences.
