摘　　要：谐波会对供电系统及相关的一些电气设备带来严重的影响:会增加电气设备的额外能耗,甚至会给它们带来安全隐患,同时也会干扰计算机及传感器等一些精密设备的工作,造成控制及测量系统的不精确工作甚至是误动作,也会造成经济损失及安全事故.文章从调速变频器产生的谐波入手,分析了谐波产生的原因及其带来的危害,并对谐波加以治理;同时也对消除谐波的各类措施进行了探讨,提出了一些新的建议和看法.Harmonics have serious influence on power supply systems and some related electrical equipment： increase the electrical equipment of the additional energy consumption, even bring safe hidden trouble, at the same time harmonic interferes with computer , sensor and other precision equipment work, causing the control and measurement system is not accurate or error action, also will bring economic loss and safety accident. As the harmonics will bring serious effect, it is necessary to manage harmonic. This article from the speed convener harmonics proceed with, analysed the cause of harmonic and its harm. Meanwhile, it also discusses about various measures to eliminate harmonics, and new proposals and views are put forward.
