摘要

在电网中，有源电力滤波器(APF)是补偿非线性负荷引起的谐波污染和无功功率的重要装置。然而，这种控制方式对有源滤波器在消除畸变电流方面的性能影响很大。因此，本文对并联型有源电力滤波器的控制进行了探讨:1)瞬时功率控制策略(p-q理论)用于提取APF的参考电流，2)自适应滞后电流控制策略(AHCC)用于性能评估。在Matlab®/ SimPowerSystems中进行了不同的案例研究，例如平衡/不平衡负载的平衡/不平衡源，平衡负载的扭曲源。仿真结果验证了该控制方法的有效性。

Adaptive hysteresis current control of active power filters for power quality improvement

In power grids, the active power filter (APF) is an important device for compensation of harmonic pollution and reactive power caused by nonlinear loads. However, the control method has a significant influence on the APF performance in eliminating the distorted currents. Henceforth, this paper explores the control of shunt active power filters based on: 1) instantaneous power control strategy (p-q Theory) for extracting the reference currents for APF, and 2) adaptive hysteresis current control (AHCC) strategy for performance evaluation. Different case studies are carried out such as, balanced/unbalanced source with balanced/unbalanced load, distorted source with balanced load in Matlab®/ SimPowerSystems. Simulation results highlight the effectiveness of the proposed control method.
