Construcción de módulos de cargas no lineales y su estimación paramétrica para estudios eléctricos y de calidad de energía eléctrica

Abstract

In the development of this thesis, an adequate choice of non-linear loads were made. In this way, load modules were built to represent residential, commercial and industrial loads and a parametric estimation program was performed, it uses the least squares algorithm and was developed in Matlab. It obtains models of polynomial and exponential expressions. They represent the behavior of the loads in relation to voltage and frequency variations. In this way, experimental data are collected with the help of the load modules, Ward Leonard system and scada system are processed in this program, it obtains results, such as: coefficients for a polynomial model, coefficients and exponents for an exponential model and curves that represent the characteristics of the load versus voltage and frequency variations. Finally, a comparative analysis is made between the harmonics generated by said loads and those established by the IEC standards.
