摘　　要：分析表明,电抗器是电力系统无功补偿中的重要关键设备,磁阀式可控电抗器利用控制电抗器铁芯饱和程度来控制电抗器容量,可以适应电压快速波动的场合。针对传统磁阀式可控电抗器在励磁过程中响应时间过长的缺点,探讨可显著提升可控电抗器响应速度的励磁装置拓扑结构,该电路结构设计了直流斩波激磁和去磁电路,可以快速灵活调节励磁绕组的励磁电流,从而快速调节可控电抗器无功容量,电抗器响应速度提升效果显著,提高电网的稳定性、安全性和运行效率,有利于维持电网系统可靠、稳定地运行。Reactor is an important key equipment in reactive power compensation of power system. Magnetic valve type controllable Reactor can Control the Reactor capacity by controlling the iron core saturation degree of the Reactor, which can adapt to the situation of rapid voltage fluctuation. In order to solve the problem that the response time of the traditional magnetic valve type controllable reactor is too long in the process of excitation, this paper presents a topology structure of the excitation device which can significantly increase the response speed of the controllable reactor, the circuit structure includes DC chopper excitation circuit and demagnetizing circuit, which can quickly and flexibly adjust the excitation current of the excitation winding, thus quickly adjust the reactive power capacity of the controllable reactor, and improve the response speed of the reactor, the stability, security and operation efficiency of the power grid are improved, which is helpful to maintain the reliable and stable operation of the power grid system.
