Abstract

The paper presents the control system of shunt active power filter (APF) with predictive reference current calculation and model based predictive current control. The novel estimator and predictor of grid EMF is proposed for AC voltage sensorless operation of APF. Proposed control system provides control of APF current with high precision and dynamics limited only by filter circuit parameters. There are presented experimental results achieved for 50 kVA APF and simulation results for design of the 2 MVA APF.

并联型有源电力滤波器的新型控制系统
提出了基于预测基准电流计算和基于模型的预测电流控制的并联型有源电力滤波器(APF)控制系统。针对有源滤波器无交流电压传感器运行,提出了一种新的栅格电动势估计器和预测器。该控制系统提供了高精度的有源滤波器电流控制,且动态控制不受滤波电路参数的限制。给出了50kva有源滤波器的实验结果和2mva有源滤波器设计的仿真结果。
