Implementación de un módulo de prácticas de laboratorio para determinar el rendimiento de turbinas pelton y francis en la asignatura de energías renovables de la carrera de ingeniería electromecánica en la universidad técnica de Cotopaxi .

In the current investigation the simulation in dynamic state and the practical conditions of a Francis turbine and a Pelton turbine have been highlighted. These are the most used turbines within the micro generation and large scale generation. The investigation is based on the problematic that there is a lack of a module of research for turbo machinery that allows an accurate analysis of their efficiency under conditions of varying heights, pressure and flow of the motor energy of the hydraulic potential. The methodological development was based on a field research and an experimental research which allowed the determination of two comparison and validation of data scenarios by means of the use of Solid Word for the simulation and practical implementation. Also, through the mechanical design with a security factor of 2,5 which is acceptable within the mechanical design, and an arduino card for reception of data, visualization of the curves of the turbine variables of operation by means of the NEXTION screen. This screen possesses a serial HMI communication to visualize the Performance Vs RPM, Pressure Vs RPM, Flow Vs RPM and Torque Vs RPM. Following the validation of the results it was analyzed that between what was simulated by SolidWorks and the practical data there is an error ranging from a 2% to a 3% which could be attributed to the calibration of the instruments of measurement. In the Pelton turbine a minimal efficiency of 52% at a height of 50 meters was determined, thus generating a Torque of 3,2 Nm and a maximum of 62 % at 60 meters and a torque of 5,6 Nm. In the Francis turbine the determined parameters were: a minimal efficiency of 48% at a flow of 16 liters per minute generating a torque of 2,8 Nm; a maximum efficiency of 58% at a flow of 25 liters per minute and a torque of 4,8 Nm. According to the validation of the research hypothesis it was proved that the implementation of the module allowed the graphical analysis of the efficiency of these turbines regarding their pressure and flow variables.
