摘要

在有源电力滤波领域，串联混合有源电力滤波器(SHAPF)越来越受到重视。现有的SHAPF控制策略是基于提取源电流谐波或负载电压谐波的，并且在源和负载平衡的情况下有效。本文提出了一种基于广义瞬时功率理论的SHAPF控制方案。该控制方案在电源平衡和不平衡的情况下都有效，能够在平衡负载电压的同时减轻电源电流谐波。给出了所提控制方案的数学公式及其在SHAPF中的应用。仿真研究验证了所提控制方案的有效性。

A novel control scheme for Series Hybrid Active Power Filter for mitigating source voltage unbalance and current harmonics

In the area of active power filtering, the Series Hybrid Active Power Filter (SHAPF) has been taken into account increasingly. Existing control strategies for SHAPF are based on extracting either source current harmonics or load voltage harmonics and are valid for balanced source and load conditions. In this paper a novel control scheme based on generalised instantaneous power theory for SHAPF is proposed. This control scheme is valid for balanced and unbalanced source conditions and is capable of balancing load voltage while mitigating supply current harmonics. The mathematical formulation of proposed control scheme with its applications to SHAPF is presented. The validity of the proposed control scheme is verified by the simulation study.
