Description

technical field [0001] The invention relates to the field of wind power generators, in particular to a cooling control method, system, equipment and storage medium for wind power generators. Background technique [0002] The copper loss and iron loss generated during the operation of the wind turbine will cause the temperature rise of the various components of the motor. High temperature is one of the main reasons for the failure of the wind turbine. For example, every 10°C increase in the winding insulation temperature will reduce the insulation life by about half. The temperature rise of the permanent magnet will increase the probability of its irreversible demagnetization, so it is necessary to control the temperature of some key components of the wind turbine below a reasonable limit. The commonly used internal cooling methods of wind turbines are air cooling and water jacket cooling. The former uses a high-power fan to drive the cooling air to flow through the generato...
