Nuevas propuestas en la teoría de la potencia reactiva instantánea : aplicación a la compensación de cargas industriales con filtros activos de potencia

Abstract

______________________________________________The most relevant formulations of the instantaneous reactive power theory are presented and studied.Each one is analyzed to obtain its control strategy, that is applied to the compensation of three-phase nonlinear loads in four-wire systems, as much concerning simulation as experimental. The obtained results are used to carry out a comparative study in which it is shown that no strategy allows to obtain balanced and sinusoidal source current for any conditions in the supply voltage. However, in this thesis, several control strategies are presented that are able to obtain different objectives from compensation in each context: constant source power, unity power factor and balanced and sinusoidal source current. Finally, in this work, a new approach of the instantaneous reactive power theory has been developed that is named tensorial and is applicable to multiphase systems.

Se presentan y estudian las formulaciones más relevantes de la teoría de control, que se aplica a la compensación de cargas trifásicas no lineales en sistemas de cuatro conductores, tanto a nivel de simulación como experimental. Los resultados obtenidos se utilizan para realizar un estudio comparativo en el que se pone de manifiesto que ninguna permite obtener intensidades de fuente equilibradas y sinusoidales para cualesquiera condiciones en las tensiones de alimentación. No obstante, en esta tesis se proponen estrategias de control que consiguen alcanzar diferentes objetivos de compensación en cada contexto: potencia de fuente de constante, factor de potencia unidad e intensidad de fuente equilibrada y sinusoidal. Por último, en esta tesis doctoral se ha desarrollado una nueva propuesta de la teoría de la potencia reactiva instantánea que se denomina formulación tensorial aplicable a sistemas polifásicos.
