Abstract

The embodiment of the invention provides a wind generating unit, a cooling system and a control method of the cooling system. The cooling system comprises a first cooling loop, temperature sensors anda controller; the first cooling loop comprises an evaporator set, a condenser and a plurality of branches; the evaporator set corresponds to multiple heating components of the wind generating unit; each branch is in liquid-path connection with the evaporator set and the condenser in a selectable mode; the multiple temperature sensors are arranged on the outer face and the heating components of the wind generating unit; the temperature sensors are used for detecting the condition temperature of the wind generating unit and outputting the condition temperature; the condition temperature comprises an outer temperature or component temperatures of the heating components; and the controller is electrically connected with the first cooling loop and the temperature sensors, is used for determining the temperature grade which the condition temperature belongs to, and controls part of branches, corresponding to the temperature grade, in the first cooling loop to communicate with the evaporatorset and the condenser. The wind generating unit is cooled with zero energy consumption.

Description

technical field [0001] The present application relates to the technical field of cooling of wind power generators, and in particular, the present application relates to a wind power generator, a cooling system and a control method thereof. Background technique [0002] The main heating components in the operation of wind turbines include: generators, converters, transformers, electrical cabinets, hydraulic systems, main bearings, etc., and these components need to operate within a suitable temperature range. With the continuous increase of the installed capacity of a single wind turbine, the calorific value of each component also increases, that is, the demand for heat dissipation of the wind turbine continues to increase. [0003] At present, the cooling methods used by various complete machine manufacturers for different models of wind turbines are also different, but the cooling methods that have been industrialized mainly include water cooling and air cooling. Small-meg...
