“…This Section presents several approximate CFL models based on model M F and its dependence on supply voltage harmonics. This dependence can be observed in the error function system of the commutation angles (6) and in the coupled admittance matrix (2) represented in the equivalent circuit of model M F (Fig. 2).…”

Low-watt compact fluorescent lamps (CFLs) may account for significant energy consumption of power distribution feeders in future years. This can lead to power quality concerns because these devices consume highly distorted currents. In order to predict CFL harmonic current emissions into networks, CFL models capable of predicting these emissions accurately are being studied. On the other hand, these models require a high computational effort in large-scale CFL penetration studies. This paper presents and discusses several approximate CFL models based on the harmonic coupled admittance matrix model which reduce the computational effort while keeping a reasonable accuracy. The performance of the models is validated with CFL laboratory measurements.Index Terms-Compact fluorescent lamps, non-linear load modeling, harmonic coupled admittance models. 0885-8977 (c)K 25 M A5 M A4 M A2 M A3 M A1 M F M I K 50 M A5 M A4 M A2 M A3 M A1 M F M I Fig. 9.

“…This improvement is particularly significant in CFLs with large ac resistances or small dc capacitors. Both models can be easily estimated [6] and included in harmonic load flow programs. However, the resolution of the load flow problem using these models may require a high computational effort in large-scale CFL penetration studies.…”

The modeling of a compact fluorescent lamp for harmonic analysis under terminal voltage variation is presented in this paper. The compact fluorescent lamp is represented with the diode bridge rectifier model, which is commonly used for harmonic analysis. The set of parameters is estimated for different values of the terminal voltage applied to the lamp. The equations to estimate the parameters and the required measurements to calculate them are presented. To characterize the lamp an experiment is carried out varying the RMS terminal voltage from 10 V to 131.6 V and for each terminal voltage value the apparent, real and reactive powers, the power factor, the current and the applied voltage are registered. To validate the model in the range of the terminal voltage, the total harmonic distortion of current calculated with the experimental signal and the total harmonic distortion of current calculated with simulation software are compared. The results show that the compact fluorescent lamp can be represented for one set of parameters in the operation range of the terminal voltage suggested by the manufacture.

Para validar el modelo en el rango del voltaje en terminales, la distorsión armónica total de corriente calculada con la señal experimental y la distorsión armónica total de corriente calculada con un software de simulación son comparadas. Los resultados muestran que la lámpara fluorescente compacta puede ser representada por un conjunto de parámetros en el rango de operación del voltaje en terminales sugerido por el fabricante.
