| 摘 要： | 单周控制有源电力滤波器具有检测量少、控制器结构简单以及鲁棒性强等优点。在分析单周控制三相四线制有源电力滤波器工作原理的基础上，利用Matlab6.5提供的电力系统工具箱对其进行建模和仿真。仿真结果表明，单周控制三相四线制有源电力滤波器在有效补偿非线性负载导致的谐波和无功电流的同时还能抑制三相负载的不平衡。单周控制有源电力滤波器以峰值电流检测的控制方式和纹波电流的存在导致补偿后的电源电流中含有直流分量。

| Abstract: | Active Power Filter (APF) with one-cycle control has such merits as few quanta need to be detected, simple control circuitry and robustness. Based on the analysis of the operation principle of a three-phase four-wire APF with one-cycle control, modeling and simulation of which are proposed using the Powersystem Toolbox of Matlab6.5. The simulation results show that the APF with one-cycle control can compensate the harmonic and reactive currents due to the nonlinear load as well as suppress the imbalance of three-phase load. The compensated current comprise DC off-set because of the existent ripple and the peak current detection of the APF with one-cycle control. |
