摘要
本文给出了圆柱坐标系下准三维行波场矢量位方程的解耦形式,并推导了基于伽辽金法的离散格式。文中证明三维场在圆柱坐标系下r—z平面的磁力线即为等(rA_(?))线。用上述方法对一台6500MVA冲击发电机端部磁场及定子端部漏电感进行了计算。
The decoupled equations of quasi-three dimensional travelling wave magnetic field in cylindrical coordinates are presented in the paper,and the discrete format based on Galerkin method is derived. It's proved that the field line on r-z plane of cylindrical coordinates is the line of equa- (rA_8) .On these basis,the end region magnetic field and end winding leakage inductance of a 6500MVA short-circuit generator are calculated.
