摘　　要：针对风电机组运行时因发电机温度高导致限功率输出的现象。论文通过对比直驱、双馈机组发电机冷却方式,结合风电机组现场运行实际,就某双馈机组发电机高温降容问题做出对比,通过改造前后发电机轴承温度、机组功率输出数据,验证改造成果的效果,解决发电机高温降容问题,保证风电机组全生命周期管理。In view of the phenomenon of limited power output caused by high generator temperature during the operation of wind power units, this paper compares the cooling modes of generators of direct drive and doubly-fed units,, combined with the actual operation of wind turbine, this paper makes a comparison on the problem of high temperature capacity reduction o fa generator with a doubly-fed unit. Through the beating temperature and power output data of the generator before and after transformation, we can verify the effect of the transformation results, solve the problem of high-temperature capacity reduction of the generator, and ensure the whole life cycle management of the wind turbine.
