摘　　要：介绍了3/12相交直流同时供电(双绕组)发电机的结构特点。在某些近似假设条件下,将 12 相4Y互移15直流绕组等效为一个3相Y绕组,然后通过适当处理两套绕组之间的耦合,得出了与耦合有关的参数间的相互关系,从而简化了d-q-0 系统的数学模型、导出了简明的电压和磁链方程及相应的d和q轴等效电路,为分析该类电机的各项性能奠定了坚实的理论基础。该文所用方法同样适用于其它结构的双绕组发电机。The structural characteristics of a 3-&12-phase synchronous generator with simultaneous AC and bridge recti-fied DC output (the double winding synchronous generator) are introduced. With some approximate assumptions, the twelve-phase four Y-connected stator windings displaced by 15(DC windings) are replaced by a equivalent three-phase Y-connected winding; then by dealing with the electromagnetic coupling between two sets of windings, the parameter relations associated with the coupling are obtained. According to the results gotten above, the concise flux-linkage and voltage equations of a 3-&12-phase double winding synchronous generator are acquired, then its d- and q-axis equivalent circuits are derived ,which provide a sound theoretical basis for the research on this kind of synchronous generators.
