摘　　要：他励式磁控电抗器(SMCR)动态响应速度慢的固有缺陷使得其动态无功补偿性能受到了限制。本文利用SMCR自身结构和内部磁通的流通特点,提出在旁轭增加辅助绕组构成辅助励磁回路的SMCR快速性改善新措施。独立辅助励磁回路可以连接在SMCR的控制绕组或工作绕组上,通过建模分析得到了两种连接方式各自的等效电路,并在Matlab/Simulink仿真平台上分别搭建了仿真模型。仿真结果表明本文给出的SMCR快速性改善措施和理论分析是正确有效的。The dynamic compensation performance of the separate excitation magnetically controlled reactor(SMCR)is limited due to such inherent defect as slow dynamic response speed.In this paper,the structure of SMCR itself and flow characteristic of internal magnetic flux is used and a new method to improve the quickness of SMCR by adding auxiliary winding to the side yoke is proposed.The independent auxiliary excitation circuit can be connected to the control winding or working winding of SMCR,the respective equivalent circuit of two connection modes is obtained by the modeling and analysis and the simulation model is set up on the Matlab/Simulink simulation platform.It is shown by the simulation result that the improvement method and theoretical analysis of SMCR presented in this paper is correct and effective.
