摘　　要：统一电能质量调节器(unified power quality conditioner,UPQC)已成为改进配电系统(或微电网)电能质量(power quality,PQ)最具吸引力的措施,成为国内外学者研究的热点。在拓扑结构和补偿量一定的情况下,UPQC的性能主要取决于控制策略。该文综述了国内外UPQC各种的线性控制、非线性及智能控制策略研究,指出目前UPQC各种控制策略的优点与不足,提出克服目前控制策略不足的无源混合控制策略和多种控制策略融合的思想,供UPQC控制策略研究者参考。Unified power quality conditioner(UPQC)has been researched by scholars at home and abroad because it is most attractive measure to improve power quality of power distribution system or microgrid.Under given topological structure and compensation,the performances of UPQC depend mainly upon control strategy.Therefore the linear control strategy,nonlinear control strategy,intelligent control strategy of UPQC,are reviewed in this paper.Advantages and disadvantages of current control strategy of UPQC are pointed out.The new passivity based hybrid control strategy and the fusion of different control strategies are given to overcome the disadvantages of current control strategy.The above content can be used as the reference for researcher.
