节能政策促进了发光二极管（LED）灯在配电网络中的使用。这些灯是非线性负载，其将谐波电流注入配电系统中，这导致系统电能质量的降低。对这些灯的建模研究将允许预测进入配电系统的谐波排放。本研究提出了一个频域LED灯模型的谐波发射计算，连同一个简单的估计程序，从实验测量模型参数的确定。两者都经过实验室测试验证。最后，一个应用程序说明了在一个典型的配电系统中广泛使用LED灯的效果，并允许LED灯模型进行比较。
Energy saving policies have boosted the use of light emitting diode (LED) lamps in distribution networks. These lamps are non-linear loads which inject harmonic currents into the distribution system, which has led to a decrease in the system power quality. Study of the modelling of these lamps would allow the prediction of harmonic emissions into distribution systems. This study presents a frequency-domain LED lamp model for harmonic emission calculation, together with a simple estimation procedure for model parameter determination from experimental measurements. Both were validated by laboratory tests. Finally, an application illustrates the effect of widespread use of LED lamps in a typical distribution system and allows LED lamp models to be compared.
