某风电场兆瓦级双馈异步风电机组发电机轴承故障分析

Failure Analysis on Generator Bearing of MW-class Double-fed WTG in a Farm

根据某风电场运行的兆瓦级双馈异步风电机组发电机轴承故障实际情况,在风电机组SCADA监控系统报警信息和故障发电机现场检查基础上,对故障电机轴承失效情况进行分析,进而分析导致轴承失效原因,最后给出后期发电机轴承维护建议。

According to the actual failure of the generator bearing of MW-class double-fed WTG in a farm, and based on the WTG SCADA monitoring system and the failure generator inspection, this paper makes an analysis on generator bearing status, and studies the reasons of generator bearing failure. In the end, advice that is about maintenance on generator bearing of MW -class double-fed WTG is given.
