谐波问题是随电力电子技术的出现而相伴产生的。谐波的负作用或者说与经典正弦波形相违背的结果,带来了电气环境的一大公害,即谐波污染。这与世界性的自然环境问题相类同,而且其影响面更大,距离更远。谐波的污染与危害主要表现在对电力与信号的干扰和影响上:
(一)电力危害方面
1. 了解旋转电机等的(换流变压器过载)附加谐波损耗,使其发热,缩短使用寿命;
2.谐波谐振过电压,造成电气元件及设备的故障与损坏;
3. 使原来的电能测量定义和方法不适应。
(二)在信号干扰方面
1. 信系统产生电磁干扰,使电话通讯质量下降;
2. 造成重要的敏感的自动控制与保护装置工作紊乱;
3. 影响功率处理器的正常运行。

Harmonic problem is with the appearance of the power electronic technology company produces. The negative effects of harmonic and classical or violates the results, sine wave form of electrical environment has brought a nuisance, namely the harmonic pollution. The natural environment problems with the worldwide, and its influence the equivalent with greater distance away. Harmonic pollution and damage to power and is mainly manifested in the signal interference and influence on:
(a) electrical hazards
1 know etc (converter transformer overload) additional harmonic losses, make its calorific, shorten service life,
2 harmonic oscillator overvoltage caused by electrical components and equipment, the fault and damage,
3 that the original power measurement definitions and method does not adapt.
(2) in the signal interference
1 letter electromagnetic interference with system, make telephone communications quality,
2 the important cause of automatic contr
