Estudio del sistema de control automático y telecomando de la minicentral hidroeléctrica Gualaceo

Abstract

In the present thesis work, are given to know the main aspects to be considered for the automation of the Hydroelectric Minicentral Gualaceo, property of ELECAUSTRO S.A, which connects directly to a feeder from the local electric distribution utility. As a starting point, the particularity of being distributed generation, are considered for the connection into the distribution network, following the recommendations of the standard IEEE 1547. Describing of the equipment that are part of the minicentral, the focuses on the operation of each one of them, identifying the input or output signals, as well as its type. Then, are defined the three major sequences of operation: start-running, normal stopping, and emergency stopping; for each sequence, the steps are developed for perform the tasks. As same for the development of the sequences, was considered the individual restrictions for each equipment, starting conditions, and the criteria for normal stopping or emergency stopping. On the other hand, is considered also the process for integration of the minicentral with the Control Center in Saymirín; presents a proposal for screens that shows the information required from the equipment to incorporate into the SCADA, and a proposal of screens for HMI for the powerhouse and the reservoir tank. Finally, presents the architecture of communication, where can be appreciated the equipment connections and communication protocols used.
