摘　　要：双馈风力发电机组目前在国内使用最为广泛。作为机组重要部件之一的发电机,其可靠性尤为关键。而发电机轴承的可靠性将直接影响机组的安全运行。通过分析双馈发电机轴承故障的原因,提出了降低轴电流的有效措施。The double-fed wind turbine power sets,in which the reliability of the generator,as one of the most important parts in it,became the key point,were the most widely used in China.However,the safe operation of the wind turbine generator was significantly influenced directly by reliability of the bearing of the generator.The effective means to decrease the bearing failure were proposed through analyzing the causes to result in the bearing failure.
