Description
technical field [0001] The invention belongs to the field of wind power generation, and in particular relates to a heat dissipation controller, a control method and a heat dissipation system of a wind power generating set. Background technique [0002] Overtemperature faults may occur during the operation of wind turbines. The wind turbine itself has an original radiator, but the heat generated by the wind turbine dissipated by the original radiator of the wind turbine is not enough to keep the wind turbine in the normal temperature range for a long time. [0003] In order to avoid frequent over-temperature faults, a radiator can be installed on the wind turbine. The installed radiator and the original radiator of the wind turbine are jointly controlled by a control signal. That is to say, the installed radiator and the original radiator of the wind turbine are started or stopped at the same time. The power consumption of the unit is increased, and the utilization efficie...
