| 摘 要： | 当前,抽水蓄能电站SFC系统中的间谐波问题日益受到重视。本文将其SFC系统模拟为常见的电流型变频器,使用谐波调制理论,并结合开关函数的傅立叶分析,分析SFC在电网侧产生间谐波的机理,建立其简化模型。作为验证,依托某变频调速系统,结合计算机仿真模拟,其对比结果表明了该模型的可靠性,从而可推广到抽水蓄能电站中应用。

| Abstract: | Nowdays,more and more attention is given to the interharmonic distortion in SFC (Static Frequency Converter) of Pumped storage power station .The aim of the paper is to describe a means for calculating interharmonic distortion due to SFC System by simulating it into a simple a current source a.c. drives and then using the modulation theory. A model of the interharmonics for application is made in this paper. Simulation experiment results are given to prove the validity of the model.The result can be similarly used in SFC system of a Pumped storage power station. |
