Cooling control method and cooling control apparatus for generator of wind turbine

A calculation apparatus, comprising:

• a processor;
• and
• a memory storing a computer program, wherein the computer program, when executed by a processor, implements a cooling control method for a generator of a wind turbine, the cooling control method comprising:
• when a starting condition of an intermittent operation device of the wind turbine is determined to be satisfied according to operation data of the wind turbine, calculating a predicted temperature of the generator after a duration required for using a frequency converter of the wind turbine to control the intermittent operation device to start up to execute a predetermined related action;
• when the predicted temperature is less than or equal to a predetermined threshold temperature, using the frequency converter to control the intermittent operation device to start up to execute the predetermined related action;
• and
• after the intermittent operation device executes the predetermined related action, using the frequency converter to control the cooling device to start up to cool the generator.
