Diseño y construcción de un prototipo de detección de fallas serie para disminuir el tiempo de interrupciones en el sistema eléctrico de distribución

Abstract

The prototype allows detecting the absence of voltage in an electric feeder of the distribution network and emits an alarm using GSM / GPRS wireless communication to the control center of EMELNORTE S.A, to take the corresponding repair or maintenance actions. The power supply of the prototype is made through a battery supplied by solar energy to guarantee the operation of the device in the absence of voltage during a power failure of the network. For the construction of prototype, Arduino's electronic components, Raspberry PI 3 B, are used with the programming software IDE and Phyton, respectively. The remote data acquisition program was made using LabVIEW® software. The remot3.it platform is used to remote device management. The behavior of an electrical network before the opening of the phase conductors in a series fault is described. The cost of the energy not supplied ENS is used as a parameter for technical and economic evaluation with the net present value NPV and the internal rate of return IRR of the construction of the prototype, considering the costs of installation, operation and maintenance of the device, to validate the project viability.
