中文摘要:

随着非线性照明设备使用的增加,民用供电网络的谐波问题日益严重。本文对几种典型的照明设备驱动电路及工作过程进行了分析及仿真研究,并对典型的照明用户谐波情况进行了实际测试。仿真及测试结果表明, 照明设备谐波电流较大,造成了配电网电流波形畸变严重,引起电压波形畸变,中性线严重过流等问题。最后,提出了民用供电系统中抑制照明谐波的具体措施。

英文摘要:

With the use of nonlinear lighting equipment increasing, the harmonic problems of civil power supply network is becoming more and more serious. Analysis and simulation research is done in this paper on the driving circuit and working process of several typical lighting equipment, and the harmonics of typical lighting loads are tested. The simulation and test results show that the harmonic current of lighting equipment is so large that results in serious distortion of current waveform in the distribution network, which causes the problems of voltage waveform distortion and neutral line over-current. Finally, specific methods are proposed to solve the lighting harmonics in the civil power system.
