节能灯照明系统谐波电流问题研究

Research on the Harmonic Current Problem of the Lighting System of Energy-saving Lamp

随着现代电力电子和建筑智能化的迅速发展和普及,电网谐波污染的问题越来越严重。由于谐波危害很大,而且谐波源分布广泛,因此对不同谐波源产生的谐波电流应逐个分析。本文针对商业建筑中大量使用节能灯作为照明灯具的情况,结合工程实际,对25W以下的具有代表性的节能灯进行实验数据采集和分析,并得到重要结论。

With the rapid development and popularization of modern power electronics and intelligent building, the power grid harmonic pollution problems are becmning more and more serious. The harmonic wave has great harm, and harmonic sources are widely distributed, so the harmonic current caused by difierent harmonic sources should be analyzed one by one. Many energy-saving lamps are used in commercial buildings. Combined with the engineering practice, experiment data acquisition and analysis are carried out to therepresentative energy-saving lamps below 25W, and important conclusions are drawn.
