我国大型水电机组转子动平衡历来采用试重周移法,其设备仪器简单,测量计算粗糙,平衡精度较差,花费时间较长,已不适应国际市场竞争。经过3年的试验研究,哈尔滨大电机研究所开发成功一种动平衡新方法——影响系数法,在清江隔河岩3号和4号机上应用结果良好,甚至优于加拿大CGE公司, The rotor balancing of large-scale hydropower units in our country has always been trial-and-error shift method. The equipment is simple, the measurement is rough, the balance precision is poor, it takes a long time and has not adapted to the international market competition. After 3 years of experimental research, Harbin Institute of Motor developed a new dynamic balancing method - the impact coefficient method, Qinghe Geheyan No. 3 and No. 4 machine application results are good, and even better than the Canadian CGE company,
