转子绕组交叉连接的倍极感应励磁发电机及其仿真

Simulation of the Double-pole Induced-excitation Generator with Cross-connected Rotor Field Coils

转子绕组交叉连接倍极感应励磁新结构可显著提高倍极感应励磁同步发电机的磁势感应系数。由于转子绕组的等效电感参数将随着交叉连接两绕组匝数比的改变而相应变化,导致转子电阻对转子绕组电流及磁势感应系数的影响大小随匝数比而不同,文章针对这一问题进行了仿真研究。所得结论得到了实验验证。

The configuration of double-pole induced-excitation with cross-connected rotor field coils can obviously increase the mmf transfer coefficient of DPIE synchronous generator.The equivalent inductance of the rotor field winding varies as the turn ratio of the two cross connected coils changed.Thus the effects of the rotor resistance on the rotor field current and the mmf transfer coefficient vary as the turn ratio.This is investigated by simulation in the paper.The conclusions are confirmed by tests.
