Abstract
The present disclosure relates to methods (100, 200) for ramping up the power output of a wind turbine (10). A method (100) comprises increasing (110) electric power output from an initial power value (61) at a first power ramp rate (63); and when reaching an intermediate power value (69), increasing (120) the electric power output to a target power value (59) at a second power ramp rate (67) different from the first power ramp rate (63). The intermediate power value (69) is the sum of the initial power value (61) and a predetermined power difference (71).
Claims14
A method for operating a wind turbine, the method comprising:
- increasing electric power output of the wind turbine from an initial power value at a first power ramp rate;
- when reaching an intermediate power value, increasing the electric power output to a target power value at a second power ramp rate that is different from the first power ramp rate;
- wherein the intermediate power value is the sum of the initial power value and a predetermined power difference;
- and
- wherein the predetermined power difference is a predefined percentage of the target power value that is determined prior to the step of increasing electric power output of the wind turbine at the first power ramp up rate.
