Highlights
The analytical derivation of this Compact Fluorescent Lamps (CFL) model is presented in detail and its performance is discussed when predicting the current of a CFL designed to operate in a 120 V 60 Hz electrical system
The constant increase of non-linear loads in low voltage grids, the mass adoption of Compact Fluorescent Lamps (CFLs) and Light-Emitting Diode (LED) based lamps, aimed at reducing power demand and improving energy efficiency in lighting systems, has led to high levels of harmonic content in the current drawn from the supply system (Blanco & Parra, 2011) (Romero, Zini, & Ratta, 2011) (Ribeiro, et al, 2011)
This paper studies the performance in a 120 V 60 Hz power grid of a novel previously proposed CFL circuit-based model via simulations and measurements of CFLs with different power ratings under sinusoidal controlled voltage supply
Summary
The constant increase of non-linear loads in low voltage grids, the mass adoption of Compact Fluorescent Lamps (CFLs) and Light-Emitting Diode (LED) based lamps, aimed at reducing power demand and improving energy efficiency in lighting systems, has led to high levels of harmonic content in the current drawn from the supply system (Blanco & Parra, 2011) (Romero, Zini, & Ratta, 2011) (Ribeiro, et al, 2011). The search for more and better models to assess and predict the collective harmonic impact of these loads on the low voltage network is currently a research topic (Salles, Jiang, Xu, Freitas, & Mazin, Oct. 2012). Several serious problems are caused by the harmonic currents flowing in the power system: overheating and overloading of conductors (especially neutrals), motors and transformers (increased losses); poor power factor and overloaded capacitor banks; undesired protection tripping and skin
