摘　　要：发电机是风力发电机传动系统的重要部件,其运行的稳定性决定整个机组的性能。发电机弹性支撑作为支撑发电机的弹性元件,起到传动链减振的重要作用。随着风电功率的发展,电机重量和扭矩不断加大,在不同工况载荷激励的作用下,发电机弹性支撑反馈的减振性能与经验选型存在差异。以某大功率机组发电机为研究对象,研究机组工况激励对弹性支撑性能的影响,为未来产品选型提供试验依据。The generator is an important part of the transmission system of wind turbine;the stability of the operation deter-mines the performance of the whole unit.The elastic support of the generator,as the elastic element supporting the generator,plays an important role in damping the vibration of the transmission chain.With the development of wind power,the weight and torque of the motor increase constantly.Under the excitation of different load conditions,the vibration reduction perform-ance of the elastic support feedback of the generator is different from that of the empirical selection.In this paper,the genera-tor of a high-power unit is taken as the research object,and the influence of load on the elastic support performance of the u-nit is studied through systematic test verification,which provides a test basis for future product selection.
