Análisis de fallas armónicas y su mejoramiento por medio de filtros activos y pasivos en un sistema de 14 barras de la IEEE

Abstract

Harmonics are a common problem in electrical systems that contain devices that can vary the frequency in the network producing nonlinear currents which if not controlled or mitigated can be harmful to the company or person with this problem. In a system of 14 bars was installed harmonic faults previously measured by harmonic measurement companies, this system was extracted from Digsilent as it complies and was designed by the IEEE which makes it a perfect example of study, based on that the system was taken and brought to ETAP with necessary modifications for proper change using the software libraries were completed data such as the general impedances of generators, transformers, loads and transmission lines. Once measured the harmonics installed in the system and verifying that its total harmonic distortion is higher than the ranges allowed by the IEEE 519 standard, we proceed to the installation of filters as a means of mitigation of these harmonics that affect the network, the calculation and testing of the first passive and then active filters is performed separately but in the same system to make a proper comparison between the two methods of harmonic control in order to determine which of the two methods of harmonic filtering is more efficient in a case similar to that presented being of 14 bars.
