Abstract:

The effective forcedair cooling of wind power engine room could ensure the safe and efficient operation of wind turbine unit in hot weather. Through building a simulation model of wind power engine room, this paper simulated the engine room before and after the installation of wind gathering cover. The results shows that the temperature in engine room drops significantly as the increasing of environmental wind speed, when the wind speed is greater than 8m/s, the temperature difference between engine room and environment is less than 3℃ and the larger the external wind speed, the smaller the temperature difference. After the installation of wind gathering cover, the failure of wind turbine unit caused by high inner temperature in engine room was reduced, and it improved the economy and safety of wind turbine unit.

Key words:
