Resumen
LEOVALDO DA SILVA MELLO, José et al. Harmonic detection and energy optimization of electrical installations using an Arduino microcontroller system. Energética [online]. 2021, vol.42, n.1 Epub 01-Mar-2021. ISSN 1815-5901.
Solutions for harmonic problems in electrical distribution networks have been frequently discussed in the recent literature. This article evaluates the use of Arduino microcontroller system connected with the power grid to reduce harmonic distortions and power factor correction. For this, it was developed a system capable of distinguishing the harmonic components of up to 13th order in a single-phase electrical system (phase-neutral) taking readings of voltage and electric current using an Arduino Due board based on a 32-bit ARM core microcontroller. We seek to analyze and propose corrections for harmonic distortions into small frames by implementing a parallel active filter to be used in harmonic elimination, as well as reactive compensation and load current balancing. The results demonstrated that a control strategy was achieved without requiring a long time in the data analysis or delay time in measurement and corrections.
