Automatización de las unidades de generación de la Central Hidroeléctrica Pucará.

Abstract

The objective was to design and implement the data acquisition and automation control boards of the two generation units of the Pucará Hydroelectric Plant, located in the Province of Tungurahua, as part of the general project of modernization of equipment that is carried out in the plant. The electromechanical control system was replaced by the use of programmable logic controllers with the purpose of improving the reliability in the control of the generation units. We considered the communications between the different equipment under the architecture designed to meet the requirements of the control system, measure the required variables of the field instrumentation supervised in local boards that allow to optimize the operation, measurement, control and supervision. In the programming of the start and stop processes, standardized functional diagrams were implemented to develop a model that simplifies the understanding of the various sequences carried out. It is concluded that the design was carried out, assembly and commissioning of the electrical system, control and monitoring for the acquisition and control units of the generation units of the Pucará Hydroelectric Plant. It is expected that the information of this project will serve as a source of consultation for the hydroelectric plant personnel Pucará.
