LED lamp modelling for harmonic studies in distribution systems

Year: 2016

Type: article

Abstract: 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.
