Estudio de alternativas de conexión para el ingreso de la micro central Hidroeléctrica San José de Minas a la red de la Empresa Eléctrica Quito

Abstract

The San José de Minas Hydroelectric Plant is a distributed generation source, which will be connected to the Quito Electric Company (EEQ) network. Before the connection, electrical studies of power flows are carried out, for the current conditions of demand (year 2017) when the study began and for those projected to the year 2019, when the plant will start operating. Then, three alternatives of connection points of the power plant with the feeder are established, the route is drawn according to established regulations, the best route is determined through a satisfaction analysis of the technical, social and environmental parameters. After that, Electric and economic studies are carried out for each alternative, in combination of both studies the best connection alternative is determined. Finally, short-circuit studies are carried out in order to determine a zone of influence of the connection from the central to the feeder. Within this area it is verified if the capacities of the cutting and sectioning equipment satisfy the requirements the new short-circuit powers and a coordination study of protections for the trunk of this feeder is made, establishing the necessary adjustments under this new operative condition.
