the increasing unit capacity of wind turbines, the heat production in the operation
procedure will increase sharply and the disadvantage mentioned above of the tradi-
tional stand-alone cooling method will be more acute. Hence, the centralized cool-
ing method is taken into consideration. As shown in Figs 12 and 13, the feature of a
centralized cooling system for wind turbines is that it sets a cooling unit in the wind
power plant, providing centralized cooling capacity to every wind turbine in it.
