Desenvolvimento de banco de dados para sistemas de abastecimento de água visando eficiência hidroenergética utilizando softwares R E Epanet

Abstract

Currently, many water supply systems collect and monitor data daily, among which we can highlight values of reservoir levels, pressures, demands, in addition to electrical consumption data. The generated data becomes information providing the necessary knowledge to direct the manager to carry out actions and decision-making in general. In addition, R is a software widely used for statistical analysis and recently in some works, a functionality of R coupling to Epanet was presented, such as: ARANDIA and ECK (2018), MACEDO (2020) and BARBEDO (2021) fact that facilitates the analysis of various hydraulic scenarios. Thus, this dissertation aims to evaluate the potential use of R and Epanet in a database of water supply systems, for this purpose it was considered for the methodology to propose a theoretical water distribution network and evaluate scenarios simulation and the results from R.After coupling, the proposed network was simulated with the variation of the reservoir level and demands in several different scenarios, thus obtaining several results. It was possible to automate the analysis process, generating graphical tables and statistical data regarding the dispersion of demands, pressures and flows resulting in the nodes and in the stretches from each demand variation and reservoir levels that were stored. The results obtained proved the compatibility and practicality of the mathematical model of water distribution designed in the Epanet software simulated in the R software.
