摘要
针对并联型有源滤波器提出了一种电流控制新方式,与传统控制方式不同,该方式不需要检测非线性负载中的谐波及无功电流.文章论述了并联型有源滤波器电流控制的等效原理,MATLAB仿真结果表明,省略了检测环节的该控制方法电路结构简单,大大简化了算法的研究,能够更加简单准确地补偿谐波电流,动态响应速度也很快.
A new equivalence principle of current control for shunt active power filters is introduced, which having no use for measurement of harmonic and reactive currents of nonlinear loads. This paper analyzes and demonstrates the principle. Simulation results by MATLAB are given to show that the equivalence principle without measurements has many merits such as simpler circuit configuration and algorithm, more exact compensation effectiveness and rapid dynamic response.
