三相电路谐波的检测与建模

Three-Phase Circuit of Harmonic Detection and Modeling

电力电子技术的快速发展,对纯净电网的要求越来越高。谐波作为影响电网质量最主要的因数之一,对谐波的检测也就非常重要。笔者以瞬时无功功率理论为基础,研究用该理论检测谐波的两种重要方法,比较这两种方法的优缺点,确定一种最适合的检测方法,建立仿真模型。

With the rapid development of power electronic technology,higher and higher requirement is placed on pure power grid.As one of the most important factors affecting the quality of power grid,the harmonic detection is very important.Based on instantaneous reactive power theory,this paper studies two kinds of important methods to detect harmonic,compares the advantages and disadvantages of the two methods,identify one of the most suitable test methods,and establishes the simulation.
