中文摘要: 有源电力滤波器中使用最广泛的谐波检测方法是瞬时无功功率法,通过研究基于瞬时无功功率理论的谐波电流检测方法,发现低通滤波器(LPF)对检测电路的检测效果影响很大.运用MATLAB仿真软件对LPF进行了大量的仿真研究,最终确定了LPF的类型,最优截止频率fc,最优阶数,使谐波检测电路的检测效率最大化,并为谐波检测电路中LPF的选取提供指导.
Abstract:The instantaneous reactive power algorithm is the most widely used method for harmonics detection in active power filter. During study of the harmonics detecting algorithm based on the instantaneous reactive power theory, it is found that the low-pass filter has important influence on the harmonics detecting circuit's performance. On the basis of simulation work done in MATLAB environment, the best cut-off frequencies, the best order and type of the low-pass filter are obtained finally, making the harmonics detecting circuit work in the best situation. The conclusions obtained in this paper are of great help to the design of the harmonics detecting circuits.
