Diseño e implementación de un sistema scada para el Control de enfriamiento del tanque de agua fría de la Planta de procesos análogos (ppa)

Abstract

In the laboratory of industrial of the University Francisco José de Caldas Faculty Technological, have own equipment automation that were not being used by students of the curricular project of technology in industrial and engineering in production. During the development of the subject "Process Instrumentation II" Engineering Control students decide to make the prototype of a didactic plant that receives the name of Process Analogues Plant (PPA) with the equipment available in the laboratory for use as a theoretical-practical tool to simulate industrial processes of automation and control of physical variables as (level, temperature, flow). The plant has a control panel, actuators, tanks, and hydraulic connections within a metallic structure. The plant does not have elements for measurement of temperature and level, nor account with control systems for these variables. In this project were selected and installed sensors of industrial type that allowed to realize a process of experimental identification by means of the software MATLAB ® there was obtained an approximate model that characterizes the behavior of the thermal system in the cold water tank of the plant, a controller PID is designed by the method of the place of the roots that is implemented in the Programmable Logical controller (PLC) Allen Bradley mark from the software RSLogix5000, and with a graphical interface developed in FactoryTalk View for screen HMI is implemented a system of supervision and control and data acquisition (SCADA).
