Ítem Diseño de un Sistema SCADA para la Planta de Procesos Amatrol T5552, de la Facultad de Medio Ambiente de la Universidad Distrital Francisco José de CaldasMendez Furque, Sandra Milena; Cañizales Santana, Heber Jhoan; Chacón García, AlfredoThe project is developed in 4 chapters: the first one is the study of control systems, itself part of the concept and classification of existing control systems is shown. Subsequently the process plant T5552 Amatrol and the 990-PS712, the son module work items, which concepts instrumentation, sensors and actuators, likewise issues of the mathematical modeling of systems become collected is presented and block diagrams; in the second chapter they are described as conditioning each sensor pressure and flow was performed to characterize their values, one from an analog signal current delivered by each para that can be done signal processing equivalent signal the pressure, height or volume variables. The instruments fed a voltage signal of 0-24 VDC and the output handle these elements is 4-20 mA, the data is stored in tables that will later be used for the mathematical model of the system; chapter third, the identification of the transfer function each paragraph one of the sensors and actuators of the plant is started, it is established that the working range of flow sensors to be only between 0 to 1.2 GPM, a due that manufacture some of the instruments are restricted by it: tank level 1, tank level 2 and flow through the pipe, using these results identify constants that tune the best: the mathematical model for each of the processes carried out to performing system controller response that will be subsequently installed to control algorithm; finally, chapter four about the concept of SCADA system to Amatrol T5552 plant exhibits characteristics that have some of the processes that are designed under esta parameter, using the hierarchical automation reference to like getting to get control the flow of processes and being level of the specific project objectives, the instruments (sensors and actuators) are defined, describing the different signs of process and all the necessary elements of the system reach para optimize the process, contains GEMMA development guide with respective states applying one of the processes of each consequently development defame all the information to the programming language for the driver, giving the final episodes of design parameters of the SCADA system and allowing identify operation screens HMI.
