用单根线棒连接法增加水轮发电机可选的对称支路数

Increasing the Number of Symmetric Branch of Hydrogenerator by Using Single Bar Connection

本文通过对水轮发电机双层绕组的分析,提出了使发电机绕组的支路对称条件扩大为4P/a=整数的设想,从理论上分析了单根线棒连接法绕组的对称性和谐波电势,并提出了降低绕组低次谐波幅值的方法。

By analysis for double-large winding of a hydrogenerator, an ider which symmetric condition of the branch is extended to 4P/a equal to integer is presented in this paper. The symmetry and harmonic EMF of the winding connected by single bar are analyzed in theory. A reduction approdch of low harmonic amplitude in the Winding is given too.
