摘要
本文介绍了映射LED光源照明安装的负载电能质量参数的测量。研究是在一个特殊构造的实验装置上进行的，该装置允许测量电致发光照明的电气参数和畸变。文中引用了电能质量领域的法律依据，参考了标准:PN EN 50160“公共电网供电电压特性”和PN - EN 61000“电磁兼容性(EMC)”。此外，还介绍了不同制造商的LED光源的比较研究，单独工作和在一个组中。给出了电流强度波形和电流高次谐波的柱状图。此外，还绘制了电流强度THDi的总谐波失真比与配合LED灯的有功功率的关系。最后对研究结果进行了分析和总结。
Measurements and analysis selected power quality parameters in systems with LED light sources
The article describes the measurements of power quality parameters of load which is mapping the lighting installation of LED sources. Study were performed on a specially constructed the experimental setup which allows for the measurement of electrical parameters and distortion from electroluminescent lighting. In the paper quoted the legal basis in the field of power quality, referring to the Standards: PN EN 50160 “Voltage characteristics of electricity supplied by public electricity networks” and PN–EN 61000 “Electromagnetic compatibility (EMC)”. Also has been presented a comparative study of LED light sources from various manufacturers, working individually and in a group. Shown the waveforms of current intensity and the bar graphs of higher harmonics of current. Additionally has been plotted the characteristics of total harmonic distortion ratio of current intensity THDi in the relation to the active power cooperating LED lamps. Finally the results of research has been analyzed and summarized.
