| 摘 要： | 基于统一电能质量调节器（UPQC）对电能质量进行补偿时的同步性问题和控制的复杂性两个方面的考虑,在对UPQC拓扑结构与工作原理分析的基础上,提出了基于单周期控制的统一电能质量调节器控制策略,完成对UPQC中的DVR和APF两部分的同步控制,拓扑结构简单、易于实现。在理论分析的基础上,应用Simulink对单周期控制的统一电能质量系统进行了建模和仿真,仿真结果表明,该方法能在一个开关周期内消除稳态误差,证明了该拓扑的实用性和控制方法的有效性。

| Abstract: | Based on the consideration of compensating synchronization and controlling complexity for the unified power quality conditioner(UPQC) compensating on the power quality,a one-cycle controlling method for UPQC is designed with an analysis of the topology configuration and principle of UPQC.This method is used to synchronously control dynamic voltage restorer(DVR) and active power filter(APF) of UPQC,and the topology structure is simple and easy to implement.On the basis of theoretical analysis,it is modeled a... |
