Estudio de perturbaciones eléctricas producidos por la iluminación de tecnología LED en una red de distribución

Abstract

This thesis deals with the study of the disturbances produced by LED-type lighting in a public lighting network that has been replaced by sodium-type luminaires. A quantitative methodology will be used to achieve a better interpretation of the distortions produced. Using the power quality analyzer (Fluke 435-II), the corresponding measurements will be made and then the disturbances generated by both the sodium-type and LED-type luminaires will be analyzed. This quality analyzer will show us the different data such as (THDi) Current Total Harmonic Distortion, and (THDv) Voltage Total Harmonic Distortion, in addition to voltage fluctuations and depressions, as well as if they are fed with a pure source with the use of a Chroma programmable power supply which allows simulations of harmonics, flickers and sags, to carry out a respective analysis and comparison of measured and simulated results, verifying whether the data measured in both fixed and variable sources comply with the regulation current related to energy quality. Finally, simulations of lighting parameters of each type of luminaire are carried out to verify whether the measurement data such as luminance and illuminance comply with the regulation regarding public lighting. Thus, having a clearer idea of the electrical distortion parameters produced by the LED luminaire compared to the sodium luminaire and which of these two types of luminaires can affect the power quality of the distribution network the most.
