摘　　要：基于磁控电抗器(magnetic control reactor,MCR)的动态无功补偿装置可直接接入1 000 kV电压等级运行,控制灵活、可靠性高,因此MCR受到广泛关注和研究。但MCR响应速度较慢的固有问题限制了它在很多场合的应用。通过理论分析得出,影响磁控电抗器响应速度的作用机理在于工作绕组中存在直流感应电压以及作用回路。提出了工作绕组串联的结构设计方案以及相应快速励磁控制策略,提高了磁控电抗器的响应速度。详细介绍了绕组配置方法及其工作原理,给出快速励磁电压显示表达式。仿真与实验结果验证了理论分析的结论,结果表明所提结构设计与控制方法可以使磁控电抗器的响应速度提高到10ms。As a kind of reactive power compensation equipment, magnetically controlled reactors （MCRs）, based static var compensator, can bedirectly put into operation in 1 000 kV voltage level with control flexibility and high reliability. For this reason MCR is widely concerned and researched. However, low responding speed has always been the crux to constrain its application. After theoretical analysis, this paper summarized primary causes, including the induced voltage by the direct-current and its inductance loops, all of which constrained responding speed of MCR. A novel physical design schedule and a fast excitation method were proposed. Moreover, the paper indicated specific winding configurations and basic operation principles after which certain functions that could work out fast excitation voltage were proposed. Simulation and experiment results verified the correctness of theoretical analysis. According to the results, the novel physical design and the fast excitation method discussed in this paper can greatly decrease the response time to 10 ms.
