Caracterización y modelamiento matemático de las corrientes armónicas resultantes generadas por cargadores de vehículos eléctricos y evaluación en un caso de estudio

Abstract

This degree project is presented the characterization and mathematical modeling of the resulting harmonic currents generated by electric vehicle Chargers, based on measurements taken in real electric vehicles as a means of data collection. These measurements are limited by the availability of equipment and accessibility to charging stations, and were carried out at the points of connection of the mobile authorized by the company responsible. With the recorded data, the characterization is effected, which determines the behavior of the variables including deviation obtained in measurements, with probability functions are achieved that can represent the behavior streams including the effect of harmonics. Subsequently, the construction of the mathematical model of current harmonics, will be starting from algorithms, data probabilistic allowing representing and showing the treatment of current harmonics produced by the Chargers for electric vehicles based on the curve of the battery, then deliver the levels of THD. Finally, there will be a case study (10 electric vehicle charging station), in which analyzes the behavior of the resulting harmonics currents and the level of THDi, identifying of problems and consequences generated by these elements in the electrical system
