摘要 |
A method for controlling an individually pitched wind turbine during shutdown is disclosed, the wind turbine comprising at least three wind turbine blades (1a, 1b, 1c). In response to a shutdown command for stopping operation of the wind turbine, a blade parameter of each of the wind turbine blades (1a, 1b, 1c), e.g. pitch angle, bending moment or blade acceleration, is determined. The blade parameters of the wind turbine blades (1a, 1b, 1c) are compared, and a shutdown strategy for the wind turbine is selected from a group of two or more predefined shutdown strategies, based on the comparing step. Finally, the wind turbine blades (1a, 1b, 1c) are moved towards a feathered position in accordance with the selected shutdown strategy. |
