Abstract
Objectives: This paper describes the process of designing a SCADA platform developed on a graphic programming environment using the Labview software tool. Methods/Analysis: Its purpose is aimed at monitoring the fuel consumption of diesel power plants and their electrical generation, making it possible through the interface and graphic indicators, to show the levels of level in the fuel tanks, the consumption of diesel in real time and electrical generation among others, in order to determine if a generator is behaving efficiently according to the indices determined by the manufacturer. Findings: If the operating criteria are not maintained, it would mean that fuel waste is being produced with the economic and environmental implications that it also implies that electromechanical corrections must be made in order for there to be efficient electrical generation. Improvements: You can use a web portal where you can monitor the system, adding a notification mode. Keywords: Electric generator, diesel, Labview, SCADA, instrumentation for level, electric power
Highlights
The appropriate use of energy resources is a priority in all industrial fields, even more for companies that use fossil fuels such as oil, coal and gas and their derivatives such as gasoline, ethanol or diesel and the latter are used to power mechanical systems such as engines for electric generation or movement generation, it is well known the rise of new energy systems that protect the environment such as wind systems, solar energy systems, hydrogen systems among others, but still its implementation, cost and efficiency for Many industrial environments are not enough to displace conventional fuels, as in the case of heavy machinery, electric generators, aviation sector, etc., where the use of fossil fuels will prevail for a long time[1,2]
Bearing in mind that for measurement projects, the instrumentation systems can be of different types, it is required to perform an independent calibration for each of these, where the signal ranges are assigned with respect to the measurement that is performed as the height of fluid that measures or the temperature, likewise in this stage, it is necessary to consider the cubic size or dimensions of the diesel tanks and their particular shape, with which it will be possible to determine the amount of diesel fuel with respect to the instrumentation signal acquired
The calculation of the current level of diesel that is present in a cylindrical tank is performed, depending on the instrumentation signal, which would come from a level sensor and which varies from 4 to 20mA, analyzing the above was reached (2), which was implemented by means of calculation blocks in the Labview software, where for a 4mA signal a tank level of zero Gallons will be obtained and, depending on the variation of the instrumentation signal, the current level will be in gallons that are in the diesel tank
Summary
Digital systems due to their characteristics of stability and reduced cost have been introduced in different fields including communications systems, within this aspect are the digital processing systems this is because it is easier to manipulate digital type signals than analog type. Because in Colombia the costs of buying efficient technology for small and medium-sized companies if they do not have the production required to support these investments, one of the best alternatives is to optimize processes, maintain equipment in use, implement affordable technologies of monitoring and supervision that contribute to maintain the equipment in its best performance and reduce energy losses. All these indexes allow us to analyze the efficiency of a mechanical system, the response of the instrumentation in the form of low power electrical signals allows to digitize them and process them, store them and visualize them as the case may be, all this history of events when. This document describes the development process of a SCADA system[4,5,6,7,8,9] on the Labview software, which is a program oriented to perform graphical programming through the interconnection of program blocks, to design a system that allows monitoring in Real time diesel consumption rates of a conventional generator
