【摘要】 采用有限元法分别计算了水轮发电机定子绕组上、下层线棒中的涡流损耗系数各取其值和都取为平均值两种情况下，定子最热段的三维温度场，分析了集肤效应对该温度场计算的影响，并给出了３２０ＭＷ和１５０ＭＷ水轮发电机的实例计算结果．更多还原

【Abstract】 In this paper,the 3D temperature field of the hottest region in the stator of hydroelectrie generator is calculated by means of finite element method,in case that the value of eddy current loss coefficient in stator winding is average or not Then the influence of the skin-effect on calculation of the 3D temperature field is analyzed,and the calculation results of 320MW and 150MW hydroelectric generator are given更多还原
