Abstract: A method of cooling a wind turbine. A cooling system is operated with a first setpoint temperature to cool the wind turbine over a first period. The method comprises 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; and 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 setpoint temperature on the basis of the comparison(s); and operating the cooling system with the second setpoint temperature over a second period. An equivalent method is also disclosed in which a power setting of the wind turbine is changed on the basis of the comparison(s).

Abstract: A cooling system (12) for a wind turbine (2), the cooling system (12) comprising: a fluid circuit (16) arranged to convey a working fluid to and from at least one component (14) of the wind turbine (2), to exchange heat between the working fluid and the component (14); a main pump (26) configured to circulate the working fluid around the fluid circuit (16); and at least one branch line (28) connected to the fluid circuit (16). The, or each, branch line (28) comprises: an inlet (30) arranged to receive working fluid from the fluid circuit (16); an outlet (32) arranged to return working fluid to the fluid circuit (16); a branch pump (36) arranged to pump working fluid through the branch line (28) from the inlet (30) to the outlet (32); and a cooling device (34) arranged to cool working fluid flowing through the branch line (28).
