Simulation Study in Current-Average Harmonic Detecting Approach using Simulink

本文介绍了一种不使用滤波器的谐波电流检测方法——电流平均值法,给出了在Simulink环境下相应仿真模型的建立方法,并对其进行了仿真研究。结果不仅表明电流平均值检测法比传统滤波器法具有较快的动态响应,而且验证了所建立的仿真系统的有效性。

This paper introducts an establishing method to the simulation system of the harmonic detecting approach without using filters, which is called curren t average method. By means of Simulink, simulation analyzing to the system is ca rried out. The result indicates that the new approach produces a faster transien t response than the conventional one using filters and that the simulation model is effective.
