Assignee: VESTAS WIND SYSTEMS A/S
Field: Engines, pumps, turbines (Mechanical engineering)
Classification: CPC F  Y | IPC F

Claim 5:
6. A method of operating a wind turbine, the method comprising:
operating the wind turbine with a first power setting to generate power over a first period;
measuring a temperature of the wind turbine over the first period to obtain temperature measurements;
allocating each of the temperature measurements to a temperature range, wherein one or more of the temperature ranges are critical temperature ranges;
for each critical temperature range, comparing a parameter indicative of a number of the temperature measurements allocated to the critical temperature range with a threshold;
selecting a second power setting on the basis of the comparison(s); and
operating the wind turbine with the second power setting over a second period;
wherein if the parameter is lower than the threshold for each critical temperature range, then the second power setting is selected to be higher than the first power setting; and if the parameter is greater than the threshold for at least one of the critical temperature ranges, then the second power setting is selected to be lower than the first power setting.
