    Mejoramiento del sistema de control y monitorización para el sistema de agua de enfriamiento NSAE de la Central Hidroeléctrica San Francisco

    In this project, the improvement of the New Cooling Water System (NSAE) is carried out, a subsystem that is a fundamental part of the electric power generation process produced by the San Francisco Hydroelectric Plant, and whose function is to maintain normal temperatures. Generation Units of the Power Plant through the storage and distribution of cooling water, with the use of pumps that lead this liquid through pipes connected to the cooling systems of the generators. The system that was installed in 2012 did not provide a local monitoring interface for the process variables, which is why it was necessary to install an HMI screen on the system control panel, thus increasing its reliability, allowing visualization complete process through monitoring the status of the elements that make up the system: pumps, storage tank levels, central air extractor, flow valves, pressure switches, temperature, flow, voltage measurements, single-line diagram of the system, three-wire diagram of frequency inverters, history of events, status of all PLC variables, status graphics of analog variables. With this improvement, it is now possible to contrast the status of the system between the new interface, the SCADA and the on-site reading of the equipment and instruments that comprise it. In addition, the design of a Modbus network is carried out that allows the acquisition of parameters of the frequency inverters from the new interface, including a new temperature sensor for the Pumping Tank. The methodology used is theoretical-practical, since the interface and network designs are oriented to the requirements of the Central, providing them with an informative, intuitive and accessible interface, thus improving the human-machine interaction between the operators and the system. through the use of industrial communication networks.
