Diseño y construcción de un banco de pruebas con sistema de control de velocidad para una turbina Michell Banki

Abstract

The objective of this project was the construction of a test bench with a speed control system by means of a PID for a Michel Banki turbine, for which the turbine runner was built with stainless steel material and in turn validated in based on the resistance of materials using Ansys and Sap 2000 software, in addition a control algorithm was developed, achieving the regulation of the turbine flow that facilitates controlling the generation parameters. For the development of the machine, the QFD methodology has been used, where it has been possible to identify the most important requirements in which more emphasis should be placed in the design, with these specific characteristics such as: the generating capacity of the impeller, the PID tuning method for regulation and control of system operating parameters. The prototype was validated through performance tests with minimum flow rates until reaching the maximum permissible value, followed by analyzing the integrity of the elements for a certain time interval, allowing the experimental results to be related to the theoretical ones that were developed in the methodological framework. Thus, it was possible to appreciate the degree of fulfillment of the determined functions. It is concluded that the regulation method of a micro generation system is feasible using a PID controller with the Ziegler Nichols experiment method. It is recommended to carry out future studies on this prototype with another control method to evaluate its effectiveness and to be able to compare knowledge of automation.
