    Diseño e implementación de un sistema para la adquisición, análisis y almacenamiento de información eléctrica en cargas residenciales y compensación automática del factor de potencia
    (2015) Alonso Aguilar, Francisco Javier; Pesántez Palacios, Aurelio Antonio; Guevara Baculima, Remigio Clemente
    A prototype based on dsPIC digital signal controllers has been designed and implemented in order to log,in function of time, the electrical data: RMS voltage, RMS current, power factor, and total harmonic distortion of voltage and current, of a residential electrical load. The electrical data are saved in a flash type microSD memory card with 2GB of capacity that allows a continuous log of the electrical parameters for a maximum period of six months. The data saving format on the microSD memory card is a text type format (files .txt) in order to allow a data analysis in any computer program that supports this format. To handle the data in an easier way, an additional data file is generated every new day (past 00H00) in the data log process. A control circuit for a capacitor bank has also been designed and implemented based on the real time measurements of the power factor in order to maintain this power factor in an optimum level. Finally, two printed circuit boards have been designed namely: the main board circuit which is the responsible of acquiring and saving the electrical data, and the drive circuit board for the capacitor bank which is the responsible of connecting or disconnecting every capacitor.
