Abstract

The configuration of a series active power filter (APF) and a parallel passive filter (PPF) has proven to be an efficient system for nonlinear load compensation. Different compensation strategies have been proposed to control the series APF. The most effective strategy determines the APF reference voltage as addition of two terms. The first one is proportional to source current harmonics and the second one is opposite to the load voltage harmonics. The control strategy has been analyzed from the state model of the single phase equivalent circuit. The resulting model analysis provides the information needed to establish design criteria for the control strategy, both in terms of harmonic filtering and the system stability. The design criteria have been applied to load type of current source harmonics (CSH). Finally, results of an experimental prototype developed for this purpose allowed the proposed analysis to be verified. The filtering equipment has been contrasted in two different situations: sinusoidal supply voltages and distorted supply voltages.

基于电流电压检测的混合电源滤波器控制策略的实用设计

并联无源滤波器与串联有源滤波器的组合是一种有效的非线性负载补偿系统。为了控制串联有源滤波器，提出了不同的补偿策略。最有效的策略是将有源滤波器参考电压作为两项的相加。第一个与源电流谐波成正比，第二个与负载电压谐波相反。从单相等效电路的状态模型出发，对控制策略进行了分析。由此产生的模型分析提供了在谐波滤波和系统稳定性方面建立控制策略设计准则所需的信息。设计准则已应用于负载型电流源谐波(CSH)。最后，为此目的开发的实验原型的结果允许所提出的分析得到验证。在正弦电压和畸变电压两种不同的情况下，对滤波设备进行了对比。
