摘要
随着非线性负载的逐渐增加,供电电源的谐波越来越严重,对电网、供电设备和用电设备的危害也越来越大。文章通过对异类辐射源系统(雷达和电抗系统)电源谐波的测试与分析,阐述了谐波产生的机理,以及功率因数与总谐波失真的关系,进而提出了降低谐波含量的措施。它对于各种实际运行的电气化设备抗谐波干扰具有一定的借鉴作用。
With the nonlinear increasing, the harmonics of the supply power is becoming so strong as to be more and more harmful to power system and the equipment of the supply and demand power. By tes- ting and analyzing power harmonic contents about the systems of Different Radiant ( Radar and Electronic Counter), this paper analyzes the reason of occurrence of harmonic as well as the relation between power factor and total harmonics distortion. With the above done, it puts forward the measures of reducing the power harmonic contents. These methods may be used for suppressing the interference of harmonics of electronic equipment.
