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. |
