风力发电机组发电机轴承脂国产化实践

Localization Practice of the Bearing Grease for Wind Turbine Generator

风力发电机组中的发电机是动能转化为电能的重要部件,决定了风电机组发电量的多少,而其中发电机组轴承润滑脂是其平稳运行的关键。文章选用了国产和进口两种发电机轴承润滑脂在黑龙江某风场运行了90天的换脂周期试验,对风机发电量和轴承运行温度进行了测试记录。结果发现,国产发电机轴承润滑脂与进口发电机轴承润滑脂相比,其运行的轴承监测温度、风机发电量与进口脂运转的数据相比,各项指标不低于采用进口润滑脂的风机,说明国产风电发电机轴承润滑脂在一个运行周期内运转良好,可以替代进口。

The generator of wind turbine is an important part of energy conversion from kinetic energy to electric energy,which determines the amount of power generation of wind turbine,and the bearing grease is the key to its smooth operation. In this paper,two kinds of domestic and imported generator bearing greases were selected to complete a 90 days grease change cycle test in a wind farm in Heilongjiang Province,and the power generation and bearing operating temperature of the wind turbine were recorded. The results show that,compared with the wind turbine with the imported bearing grease,the operation indexes of the wind turbine with domestic bearing grease,such as the monitoring temperature of the bearing and the power generation of the wind turbine,are not lower than those of the wind turbine with the imported grease,which indicates that the domestic bearing grease runs well in one operation cycle and can replace the imported one.
