摘　　要：由于常规同步调相机的转子只有一套励磁绕组,无法调节励磁磁势方向,使其静稳定极限限制了进相吸无功的能力,故本文提出了一种转子有两套励磁绕组的双轴励磁调相机的电磁设计方案,以实现励磁磁势方向可调和静稳定极限解除。通过对非对称励磁绕组、对称励磁绕组两种结构形式的分析计算,最终设计出对称励磁绕组结构形式的样机方案,从而达到均衡两套励磁绕组励磁参数的目的。本文为双轴励磁调相机的电磁设计和样机制造提供了理论基础。There is only one set of excitation winding on the rotor of conventional synchronous condenser,and the direction of the excitation magnetic can not be adjusted,so that the ability of reactive power absorbing is restricted by its static stability limitation.In order to realize the adjustable direction of excitation magnetic potential and the lifting of static stability limit,this paper put forward electromagnetic design schemes of the dual-axis excited condenser with two sets of excitation windings.Through the analysis and calculation of asymmetric excitation winding and symmetrical excitation winding,the final prototype scheme of symmetrical excitation winding structure was designed,so as to balance the excitation parameters of two sets of excitation windings.This paper provided a theoretical basis for the electromagnetic design and prototype manufacturing of dual-axis excited condenser.
