| 中文摘要 | 动态电压恢复器(Dynamic Voltage Restorer,简称DVR)是一种基于逆变电压源型串联类电力电子补偿装置,是目前解决电压跌落问题最经济、有效的手段之一。研究表明,目前采用的负荷电压反馈控制技术,由于滤波器的存在,造成稳定裕度不够和输出电压的阻尼太低,暂态品质一般。介绍了一种新型双闭环控制器,它采用负荷电压外环和滤波器电容电流内环的双闭环控制策略,可使系统的阻尼比和自振荡频率大幅度增加,从而大大改善了DVR装置的动态性能。仿真和实验结果验证了该双闭环控制策略的有效性。; Dynamic Voltage Restorer(DVR) is a novel and all-round type of power electronics device based on volt-age source Inverter(VSI),which is one of the most effective means to solve voltage sag problems at present.It is shown that the existing load voltage control strategy used in DVR can produce poorly damped response due to the presence of the switching harmonic filter in the restorer.This paper proposes a new double close-loop control strategy with incorporating in-ner capacitance current loop and outer load voltage loop,which can improve more damping and better dynamic response of the system compared to the existing scheme.The performance improvement of DVR with double closed-loop control strategy is verified by simulation studies and field experimental test.; 国家“九五”重点科技攻关资助项目(96-A19-05-02)~~ |
