Diseño e implementación de los circuitos de control para cuatro habías de 69kV de la subestación de Velacruz

Abstract

The Velacruz substation belonging to the Empresa Eléctrica Regional del Sur S.A. (EERSSA), is being expanded and modernized in order to improve the quality and continuity of the electric service; besides allowing the integration of the substation with the SCADA system of the EERSSA. The present graduation project presents the design of the circuits of control of the four bays of 69kV of the substation Velacruz, for the control of the equipment of maneuver and protection of the transformer of power and the three lines of subtransmisión Catamayo - Velacruz, Velacruz - Chaguarpamba and Velacruz - Catacocha. The study is carried out in the Velacruz substation, located in the Paltas canton of the province of Loja. Fieldwork and information survey of the primary equipment, diagrams and plans have been carried out in order to determine the needs in terms of control and force circuits. As a result of the project we present the update of the equipment drawings and single-line diagrams, the control and strength wiring diagrams of the 69kV panels and the list or wiring diagrams of the panels. Finally, the conclusions and recommendations of the project are established.
