摘　　要：以400 MW水轮发电机为例,应用Magnet有限元软件对电机不同阻尼系统进行仿真计算,分析额定工况、负序工况下转子各结构件损耗和电磁力,分析电机突然短路工况下冲击电流、瞬变电抗及超瞬变电抗等重要参数,综合分析各项指标参数确定电机最优阻尼系统。In this paper,the 400 MW hydrogenerator is taken as an example,and the finite element software Magnet is applied to make simulating calculation of the different damping systems of the motor,so as to analyze rated condition,the loss and electromagnetic force of each rotor structural component under negative sequence working conditions,analyze the important parameters such as impulse current,transient reactance and supertransient reactance under sudden short circuit and so on and meanwhile,the optimal damping system of motor is determined by comprehensive analysis of each index parameter.
