摘要
励磁调节器所引入的谐波电流会引起12相功率绕组的不对称工作。为了研究谐波不对称的产生机理,该文在建立基于基波的12/3相双绕组感应电机dq0模型的基础上,通过对两套绕组间的谐波耦合分析,经过简化,得出了可用于谐波分析的等效电路模型。从中得到了规律性的认识,为该类电机的设计和推广起到了促进作用。试验与理论分析结果的对比说明了所建模型和分析方法的正确性。
The harmonic current injection of excitation regulator will induce the asymmetry pattern of the rectifier bridge of power winding. On the basis of the dq0 equivalent circuit of 12/3-phase induction generator, a equivalent circuit model for harmonic analysis is presented through the analysis of the harmonic coupling between two windings, in order to acquire the operation principle of harmonic asymmetry. The recognition of the system rule advances the design and extensive application of the system, which is drawn from it. The comparison between the calculated and experiment results verified the validity of the mathematical model and analytical method.
