摘要
本文将派克变换推广到P对极n相对称系统的一般情形,推导了在p对极n相对称系统的一般情形下的派克变换矩阵和星网交换关系式。本文介绍的方法可被用于分析多相电机,如在大容量变频调速系统中常用的双Y6相电机;应用本文介绍的方法,仅需借助于4阶的经典派克模型就可获得异步电机完型绕组中各部分的电流分布;本文介绍的方法还可被用于分析大型电机电枢绕组的某些内部故障。
The Park's transformation is generalized to ρ-Pair pole η-phase symmetric system.The Park's transformation matrix and the polygone-star transformation relation in the general case of ρ-Pair pole η-phase symmetric system is deduced. The application of these results PermitS to obtain the current in every part of the squirrel cage of induction motors; it also offers a method to study multi-phase motors and to analyse large electric machines with internal faults of stator windings.
