Harmonics and resonances in the low voltage grid caused by compact fluorescent lamps

The effects of a widespread use of Compact Fluorescent Lamps (CFLs) on harmonics in the low voltage grid are analyzed. Therefore, measurements of the harmonic characteristics of nine different brands of CFLs are done. Based on these measurement results, a simulation model is developed, which enables to study the interaction of multiple CFLs. Thereby, the harmonic content of both currents and voltages are considered. Additionally, the impact of the capacitive behavior of CFLs on resonances phenomena is investigated and its consequences for the harmonic spectrum are represented.
