| 摘 要： | 在分析单相统一电能质量控制器（unified power quality conditioner,UPQC）瞬时功率平衡关系的基础上，提出一种基于自适应滤波电流检测的UPQC双电流源协调控制策略。鉴于电流检测精度对双电流源控制策略补偿性能的影响，在保留变步长自适应算法快速性的前提下，提出一种提高电流检测精度的定频率滤波器改进算法。针对双电流源UPQC的控制器设计，采用比例控制和重复控制构成复合控制实现了串、并联有源电力滤波器的电流跟踪控制；从UPQC整体出发建立直流电压闭环控制的小信号模型，为直流电压环的控制器参数设计提供理论指导。研究结果表明，基于该控制策略和控制器设计方案的UPQC系统实现了较好的负载电压和电网电流补偿效果。

| Abstract: | With a general analysis on instantaneous power balance relationship for a single-phase unified power quality conditioner(UPQC),this paper proposed a dual current sources coordinated control strategy based on the adaptive filter current detection for UPQC.Considering that the current detection accuracy has great influences on the compensation performances of the proposed control strategy,a fixed frequency filter algorithm for improving the detection accuracy was then proposed on premise of preserving the rap... |
