It is described a method of determining the quality of an initial value for a blade pitch angle. The method comprises (a) measuring an initial power captured by a wind turbine (100), while the blade pitch angle has the initial value, (b) changing the blade pitch angle to a first value in a first direction, (c) measuring a first power captured by the wind turbine (100), (d) changing the blade pitch angle to a second value in a second direction being opposite to the first di-rection, (e) measuring a second power captured by the wind turbine (100), (f) calculating a power difference between the first power and the second power, and (g) determining the quality of the initial value based on the calculated power difference. It is further described a control system (130), a wind turbine (100) and a computer program, which are all adapted to carry out respectively to control the above de-scribed method. |
