    In the generation of energy by means of engines fed by a fuel, in this type of plants, the components that make it up, such as the engine and the alternator, are generally called a group. The present experimental work was developed through an investigation of internal combustion engines and synchronous alternating current generators, with the aim of analyzing the availability of the machines through failure analysis and failure modes (AMFE) in the main components, taking Weibull's mathematical method and graphic model as one of the main parameters where the reliability of the components is analyzed using Technical Note NTP 331, in the criticality analysis the most critical elements were determined using Technical Note NTP 679, the same data that served to carry out a statistical model with tests that accept or reject the hypothesis, and through investigations, proformas, some acquisition costs in engine components were determined. Through the analyzes carried out, it is determined that the motors are in a stage III of increasing failures, demonstrating that the failures and failure modes affect the availability of the thermal generators of the Lligua Thermal Power Plant belonging to the Central North Regional Ambato Electric Company S.A.

    Diseño y construcción de un sistema de generación eléctrica utilizando energía hidráulica de canales de riego

    The objective is to design and build an electricity generation system using irrigation channels, in order to evaluate the potential that irrigation channels have generating electricity, as well as to find new renewable and sustainable energy sources. The irrigation channel that will be used in this research is the Huachi – Pelileo channel. The methodology begins with the collection of data on the speed of water and the flow that exists in the irrigation channel. The ANSYS software was used for the design of the turbine, in which the existence of cavitation in the turbine blades and the resistance of the turbine components were analyzed based on the Von Mises failure criteria. Then, the transmission system was designed based on the calculated rotation speed of the turbine and the speed required by the generator to operate. Finally, the construction and the evaluation of the generation system was carried out. The result obtained was a maximum power of 422.1 Watts in the test carried out in the workshop, in which the correct operation of the generation system was guaranteed. However, a simulation carried out in the SolidWorks software determined a maximum power of 1 kilo Watts. This value is due to the fact that the environment of the irrigation channel could not be recreated in the workshop.

    The present technical project was based on the study, design and construction of: a galvanized steel support plate, in addition to pulleys coupled to the motor shaft, which work by means of a belt transmission system, all these components are integrated to the 3w motor -85 xi, we also proceeded to the selection of the components for the power supply of the unmanned aerial vehicles of the CIDFAE, using the test bench duly implemented with aeromodelling equipment such as AC / DC converter, battery YTX9 - BS IGEL 12V, DC / DC converter, sending the signal through the Futaba r6014Hs receiver, and feeding the Futaba s3305 servos these equipment are correctly installed and controlled through a radio control managed by the corresponding technician of the institution and under a technical order, with the development of this project it was possible to generate autonomous energy with around 30 amps and 12 volts, contributing to the greater flight autonomy of the prototypes.
