Diseño de un sistema fotovoltaico hibrido para disminuir el consumo de energía eléctrica (KWh) de una extrusora de plástico en fábrica de empaque de vía a Daule.

Abstract

In this work, a technical and economic design for a hybrid photovoltaic system is developed, consisting of a solar generation system, the local electrical grid, and a diesel generator, which will be applied to an industrial plastic extrusion process located on the Daule road in the city of Guayaquil, Ecuador. The mentioned system has the main function of reducing the consumption of electrical energy supplied by the Cnel distribution network, as well as decreasing production operating costs and improving reliability. The energy consumption of the extruder is monitored and controlled, and a study is carried out on the available solar resources and the corresponding dimensions of the photovoltaic system, three-phase industrial inverters, and a backup generator. In addition to our design, we include the calculations and dimensions of the DC/AC protections, conductors, and respective grounding, all in accordance with current regulations in Ecuador. In order to project the annual production generated by the photovoltaic system under study and its contribution to reducing local electricity consumption, a simulation was carried out using PVsyst software. Additionally, a cost-benefit economic analysis is implemented to consider the contribution to energy savings and the payback period of the investment. Finally, it is demonstrated that the project is viable in the industrial sector, as a significant reduction in local network energy consumption and an improvement in the operational process are confirmed.
