Method for operating a wind turbine in the event of a grid error and a wind turbine for carrying out said method |
摘要 |
The invention is directed to a method for operating a wind turbine in the event of a grid error. The wind turbine has a rotor having a rotor blade adjustable in its blade pitch angle, a generator and a unit for capturing an actual value of the rotational speed of the generator, a value of the blade pitch angle and an actual value of a variable which is representative of a generator torque. The method includes recognizing a grid error; capturing the actual value of the generator torque and actual value of rotational speed of the generator when a grid error was recognized; determining a change in torque; capturing the pitch angle; determining a corrective value for the pitch angle in dependence upon the change in the generator torque and the value for the pitch angle; and, determining a corrected set-point for the pitch angle. |
