摘要:
随着我国电力系统的快速发展,可调电抗器作为可动态补偿无功和稳定电压的新型FACTS装置,得到了广泛应用.变压器式可调电抗器响应速度较快、易实现高压应用,成为研究热点.基于一种潜力较大的变压器式混合控制型可调电抗器拓扑,阐述了晶闸管投切和VSC闭环PWM调制的混合控制策略.针对存在绕组高短路阻抗设计误差和各绕组互感影响难题,目前大部分研究均从结构优化角度进行改进.从控制角度入手,将可调电抗器的整体输出无功引入到VSC的闭环控制中,提出了一种无功顶层闭环反馈控制方法,实现了可调电抗器整体输出的精确控制.此外,研究表明,相比电流内环PI控制器,采用电流滞环控制可提高可调电抗器输出的暂态性能.
Abstract:
With rapid development of electric power systems in China,controllable reactors have been used widely as a new type FACTS device which can dynamically compensate for reactive power and stable voltage.Characterized through rapid response speed and easy highvoltage applications,the controllable reactor of transformer type (CRT) has become a research hotspot.This article expounds a hybrid control strategy containing SCR switching control and VSC closed-loop PWM,based on the topology of hybrid controllable reactor of transformer type (HCRT) of a considerable potential.In view of its design errors with high short-circuit impedance of the winding and mutual inductance influence between windings,most researches focus on structure optimization at present.From the control angel,by introducing overall reactive power output of the controllable reactor into the closed-loop control of VSC,this paper proposes a top closed-loop feedback control (TCFC) to realize accurate control of overall output of the controllable reactor.Furthermore,research results show that current hysteretic control can achieve better transient performance of the controllable reactor,as compared with current inner-loop PI controller.
