针对目前研究电磁耦合系统时普遍采用等效电路的分析方法,基于线圈的回转器模型和磁流概念,提出了利用磁电等效图对电磁耦合元件进行分析的方法.应用该方法研究电抗器等电磁耦合元件,能直观反映其中的电磁能量转换过程,同时具有计算简便的特点.利用电路和磁路网络分析定律,将磁电等效图用于分析变压器供电的三相不对称系统,算例计算结果与对称分量法计算结果吻合.从而验证了基于回转器模型磁电等效图的正确性和其用于分析含变压器等电磁耦合元件不对称系统的有效性.

While the equivalent circuit is normally used in the study of magnetoelectric system,it is proposed to apply the magnetoelectric equivalent diagram in the analysis of magnetoelectric components,which is based on the concept of magnetic current and gyrator model.The energy transformation process of magnetoelectric components,such as reactor,can be directly presented with simple calculation.By the laws of electromagnetic network analysis,the three-phase unsymmetrical system powered by transformer is analyzed with the magnetoelectric equivalent diagram.Its calculative result is consistent with that by symmetrical component method,which verifies its correctness and effectiveness.
