Abstract

The invention discloses a centralized cooling system for a wind turbine generator system. The centralized cooling system comprises a generator, a water pump, a tee, a first radiator, a second radiator, an oil-water heat exchanger and a gearbox, wherein the tee is connected with the water pump, the first radiator and the second radiator respectively; the first radiator, the generator and the water pump are communicated in turn; the second radiator, the oil-water heat exchanger and the water pump are communicated in turn; and the oil-water heat exchanger is connected with the gearbox. The centralized cooling system integrates the generator and a gearbox water cooling system to eliminate the redundancy of the system. Meanwhile, two electric temperature control valves are adopted in the system, and the flow rates of refrigerating media of the generator and the gearbox water cooling system can be respectively adjusted by automatically adjusting the opening of the temperature control valves according to water inlet temperature of the generator and the gearbox, so that temperature rise of the generator and the gearbox can be simultaneously controlled.

Description

Technical field: [0001] The invention belongs to the field of wind power, and relates to a cooling system, in particular to a centralized cooling system for wind power generating sets. Background technique: [0002] At present, with the continuous increase of the power of a single wind turbine unit, the main heat-generating components, the generator and the gearbox, are gradually adopting a water cooling system to improve the heat exchange efficiency. The gearbox has changed from the original air-cooled oil to oil-water cooling Secondary cooling scheme with wind and water cooling. At present, there is a set of water cooling systems for the generator and the gearbox respectively, which are independent of each other. The two systems are redundant, and there is no automatic flow adjustment control function. Invention content: [0003] The centralized cooling system for the wind power generating set of the present invention adopts a set of water circulation cooling system, wh...
