| 摘 要： | 通过对基于瞬时无功功率理论的一种谐波电流检测方法的研究，利用ＭＡＴＬＡＢ仿真软件建立了相应的仿真电路，就其中的低通滤波器对谐波电流检测效果的影响进行了仿真研究。结果表明，低虎波顺的截频率、阶数和类型对检测电路的动态响应过程、检测精度都有很大影响。文中的仿真研究结果能为设计谐波检测电路提供指导。

| Abstract: | The MATLAB simulation software is used to model the harmonics detection circuit, which is based on the instantaneous reactive power theory. The simulation results show that the dynamic response and the detecting precision can be greatly influenced by the cut off frequencies, the order and the type of the low pass filters in the harmonics detection circuit. The conclusions obtained in this paper are of great help to the design of the harmonics detecting circuits. |
