APF空间矢量预测电流控制策略研究

影响有源电力滤波器性能的两个关键环节是无功谐波电流检测环节和电流跟踪控制环节。本文先阐述APF的原理与系统结构,然后对基于ip-iq运算方法的谐波电流的实时检测方法进行论述。为提高APF的电流跟踪性能,采用电压空间矢量预测电流控制方法。最后仿真实验表明,该方法具有更好的电流控制效果。

SVM Based Predictive Current Controller for a Active Power Filter

The performance of active power filter is affected by the reactive and harmonic current detection link and the instruction current tracking control link.The paper first expatiate the principle and construction of APF.Then discusses the measurement to pick-up the harmonic current based on the ip-iq method.In order to improve the current tracking performance of APF,in this thesis,the voltage space vector predictive current control for APF is used.The simulation results show that the current control method hav...
