Diseño de D-STATCOM controlado por teoría de componentes simétricos instantáneos (ISCT) para disminuir armónicos y corregir el factor de Potencia en sistemas de distribución eléctrica ante la presencia de cargas no lineales

Abstract

The present academic research work proposes a compensation method type D-STATCOM (Static Distribution Compensator) is by means of the Instantaneous Symmetric Components Theory (ISCT). Designed for the compensation of unbalanced electrical distribution systems, in order to reduce harmonic distortion and power factor correction. This technique (ISCT) decomposes current and voltage signals for harmonic content analysis. Two analysis cases were proposed where non linear loads with high harmonic generation are integrated. In case 1, it is sought to analyze the operation of the D STATCOM by integrating it into an unbalanced three-phase system where it will be connected in periods of time of 0.05 [sec]. The results achieved were the reduction of harmonics that remains within the limits mentioned in the document and the improvement of the power factor that ranges from 0.85 to 0.97. For case 2, an unbalanced IEEE 13- bar unbalanced distribution system was analyzed. As a result, in the case studies there is a power factor correction from 0.85 to 0.92, in addition to a reduction in the distortion of voltage harmonics from 24.49% to 5.19% and the current of the 19.62% to 10.81%. in order to reduce the percentage of harmonics and the power factor improvement.
