双馈发电机定子引出线故障处理

Troubleshooting for Stator Lead Wire of Doubly-Fed Wind Power Generator

双馈风力发电机组是国内使用最为广泛的机组。为了提高机组运行的可靠性,作为重要部件之一的发电机,其可靠性尤为关键。通过分析了一起双馈发电机定子引出线故障处理过程,明确了兆瓦级风力发电机引出线的固定须采用焊接的方式,提高其可靠性。

Doubly-fed wind turbine is the most widely used generating unit in China.Reliability of the generator,the most important unit component,is of vital importance in improving the reliability of unit operation.This paper analyses the fault processing of the doubly-fed generator stator lead wire,and concludes that,to improve its reliability,the megawatt wind turbine lead wire should be fixed by welding.
