Determination of parameters and performance analysis of load models for fluorescent recessed lightings before power supply signal variations

Abstract

The high utilization of nonlinear devices in buildings increases harmonic distortion in the electrical voltage and current signals, which has led to the requirement of characterizing and predicting the impact of such devices on low-voltage networks using load models. One of the charges that still performs an important role in the energy consumption of commercial, industrial, and educational buildings is the recessed fluorescent light with electronic ballast, which is commonly used in Colombia. However, information regarding the modeling of their behavior in the case of distorted power supply voltages is scarce. Therefore, this work presents the parameter configuration and performance analysis of two load models in the time domain, i.e., ZIP and exponential, and one model in the frequency domain, i.e., Norton equivalent model to the coupled admittance matrix method, for two commonly used recessed fluorescent lights.
