Calculation of saturation parameters and temperature field for turbo-generator stator winding with different structure
Pages: 25-34
Year: Issue:  3
Journal: Electric Machines and Control

Abstract: 以150MW空冷汽轮发电机为例,为研究定子绕组异结构对发电机饱和参数与温度场的影响,给出发电机的求解域和数学模型.利用有限元方法,计算了汽轮发电机在额定状态下,定子绕组上、下层线棒不等股数不等截面和等股数等截面两种结构下的负载场,并分析了穿越气隙进入定子齿槽的磁通大小及沿定子内圆周向的变化情况,得到定子绕组不同结构下,磁场的变化情况;在负载场基础上,计算了额定状态下的定子绕组两种结构时的直、交轴同...
