中文摘要：
磁阀式可控电抗器（magnetic-valve controllable reactor,MCR）的绕组结构与其过渡过程快慢（快速性）关系密切。根据相关文献对他励式MCR快速性的改进思想,分别对自励式MCR、传统他励式MCR以及串并联型他励式MCR的3种不同绕组结构进行对比分析,研究各工作绕组以及控制绕组上的交流和直流感应电动势的大小,并分析得到影响3种MCR响应速度的根本原因。同时,基于MATLAB/Simulink仿真平台,提出采用多绕组变压器模型搭建3种MCR快速性仿真模型,并进行快速性实例仿真和对比分析。通过制造MCR样机进行实验验证了理论分析和仿真结果的正确性。讨论结果表明：串并联型他励式MCR的工作绕组结构能有效地改善MCR的快速性,综合优势明显,且对其进一步的快速性改善仅需减小其控制回路时间常数即可。文中工作为帮助认识影响MCR快速性的机理提供基础,并提供一种MCR快速性仿真建模方案。
英文摘要：
Winding structure of a magnetic-valve controllable reactor（MCR） is closely related to its transition process speed（quickness）. Based on ideas about quickness improvement of external-excited MCR in relevant literatures, winding structures of self-excited, traditional external-excited and series-parallel external-excited MCRs are compared and analyzed in this paper. Root causes influencing response speed of these three MCR wingding types are obtained by studying and analyzing AC and DC induced electromotive forces in MCR working and control windings. Quickness simulation models of these MCRs are proposed based on MATLAB/Simulink multi-winding transformer model. Quickness of the three MCRs is simulated and compared, and correctness of theoretical analysis and simulation is confirmed by manufacturing a MCR prototype and performing corresponding experiment. Analytical results show that series-parallel separated working winding structure can improve MCR quickness effectively and possesses obvious comprehensive advantages. Quickness can be further improved only by changing time constant of control winding for series-parallel external-excited MCR. The works in this paper are helpful to understand MCR quickness influence mechanism and provide simulation modeling scheme for MCR quickness.
