Diseño de un Sistema de Potencia para la Eliminación de Distorsiones Armónicas Provocadas por Cargas Inductivas.

Abstract

Ir raises the design of a power system for the Elimination of harmonic distortions caused by inductive loads in the Faculty of electronic engineering control and industrial networks from the Polytechnic School of Chimborazo. This project is way to be applied in homes and to reduce the distortion produced by induction cookplate harmonica, which was selected to the active power filter due to its great performance and adaptive design load. For design took into consideration a load whit power 6300W and connection to the biphasic whit line voltage line to line to 220V. with these parameters was obtained a bank of capacitors for 800uf current compensation and an inductance of links of 6.9mH to the filter body, applied control closed though operational amplifiers-loop and to the power amplifier was implemented whit Mosfet transistors thus obtaining the active filter which operating achievement a reduction of harmonic of 29% compliance rules established by CONELEC laying down one range of less than 10% harmonic distortion. To achieve a harmonic distortions-free electrical system it is recommended to implement this system in very home, fot it economy, because execution removes distortions that are transmitted in the mains and contaminate other appliances causing, damage and requirements for constant maintenance or replacement.
