摘　　要：研究分析变频器节电与变频后产生的谐波附加损耗互相矛盾的问题,进行了变频器节电优化分析,提出了变频器投切算法、滤波器投切算法,与现有的变压器投切算法结合,能够有效降低系统谐波损耗,提高传动系统变频控制节电的整体效益。The conflicting problem of frequency changer’s application for energy-saving and harmonic loss is proposed in this paper. The scheduling algorithms of frequency changer and filter are researched. These algorithms and the scheduling algorithms of transform can reduce the harmonic loss, and improve the whole benefit of drive system with frequency changer for energy-saving.
