This paper presents a study and simulation of transformer configurations to improve power quality; it provides theoretical support based on the expansion of the Fourier series and analysis of symmetrical components. A test system was set up in the laboratory, taking measurements and checking configuration effectiveness in reducing the system's harmonic content. The configurations were modelled with PSCAD / EMTDC software, using two 6 pulse rectifiers as test loads and two variable speed drives.
Este artículo presenta el estudio y la simulación de las configuraciones de transformadores para el mejoramiento de la calidad de energía, mostrando el sustento teórico basado en la expansión de las series de fourier y el análisis de las componentes simétricas. Se implementa un sistema de prueba en el laboratorio, realizando mediciones y verificando la efectividad de las configuraciones en la reducción del contenido armónico del sistema. Las configuraciones son modeladas utilizando el software PSCAD/EMTDC empleando como cargas de prueba rectificadores de 6 pulsos, así como variadores de velocidad.
