基于自适应滤波的单相统一电能质量控制器研究
Research of Single-phase United Power Quality Conditioner Based on Adaptive Filter
摘要
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 rapidity of traditional variable-step adaptive algorithm. In view of the controller design for the UPQC in dual current sources mode, a compound controller incorporating P controller and Repetitive controller was adopted to implement the current tracking control for the series and parallel active power filters, and a small signal model of DC link voltage closed-loop control system on the whole UPQC was presented to provide theoretical indications for designing DC voltage loop controller parameters. The research results show that the UPQC based on the above-mentioned control strategy and controller design methods realizes favorable load voltage and source current compensation performances.关键词
