| 摘 要： | 变频器产生的间谐波问题在电力系统中日益受到重视。本文以常见的电流型变频器为例,使用谐波调制理论,并结合开关函数的傅里叶分析,分析电流型变频器的等效阻抗特性,进一步推算电流型变频器在电源侧产生间谐波的机理,并由此建立适合工程应用的变频器间谐波模型。作为验证,依托某抽水蓄能电站实际变频起动装置,结合计算机仿真模拟,其对比结果表明了该模型的可靠性。

| Abstract: | Inter-harmonics in frequency converters has gained more and more attention.This paper takes common current source inverter(CSI)as an example,and adopts the modulation theory and Fourier analysis of the switch function to analyze the equivalent impedance characteristic of the CSI, and further deduce the mechanism of CSI producing harmonics in the source side,from which the inter-harmonic model of frequency converter for engineering application is established.Relying on the practical variable frequency starti... |
