摘要
目前对抽水蓄能机组变频启动过程的谐波限制尚无可遵循的标准,国内一般对此要求过高。本文提出蓄能电站谐波限制的考核点及限制指标。对变频装置的几种典型接线方式所产生的谐波影响作了大致的定量分析,并提出推荐方案。
There are few harmonic control standards to follow in variable frequency drives of pumped storage units at present. Too strict demands are made on this in China. The examination and restriction criteria for harmonic control of pumped storage units are put forward in this paper. The harmonic influences of frequency converters with different wiring patterns are analyzed quantitatively and the recommendable scheme is presented.
