摘　　要：电子镇流器具有节能、无频闪、起辉电压低等显著优势,但是它同时会给电网带来大量谐波。通过试验分析电子镇流器对电网电流的影响,研究讨论几种能够降低谐波含量的方法并进行理论分析,提出采用基于自适应谐波检测算法的有源滤波技术,通过在PSIM仿真软件上搭建单相并联有源电力滤波器模型,仿真验证采用自适应谐波检测算法的APF对电子镇流器谐波有很好的滤除效果。Electronic Ballast has many advantages,such as energy saving,zero-stroboscopic and low voltage-up,but it also brings a large number of harmonics.Analysis of the influence in power grid through the experiment,this paper discusses several methods to reduce the harmonic content and gives theoretical analysis to them.At last,a method based on adaptive active filter technology is put forward.Single-phase parallel active power filter model is constructed in PSIM;The APF has a great effect upon removal of electronic ballast harmonics through simulation verification.
