Plan para la migración del sistema primario desde 6,3 kV hasta 22,8 kV en la zona centro norte del Distrito Metropolitano de Quito

Abstract

The present work focuses on the planning of new service areas at 22.8 kV through the demands projected by micro area under saturation conditions for the Iñaquito and Carolina substations. Simulations are carried out in the Cymdist software, transferring the diversified demand at the primary level to a transformer level, which allows the implementation of new transformers in those micro areas that need additional power. At the same time, the necessary guidelines are established for the migration of the current network from 6.3 kV to 22.8 kV in the Republic of Salvador sector, trying to re-use the equipments as much possible, for which information is collected in the area of Study with the purpose of establishing an adequate dimensioning of the new transformers. The sizing involves calculating the residential, commercial and demand projections on unconsolidated land that is based on the municipal ordinances, defining the coefficient of occupancy of the land, maximum height and minimum area of construction. Finally the modeling of the network in half voltage at 22.8 kV and contingency evaluation, where voltage drops, line loadings, maximum currents, etc. are verified, are within the ranges allowed by the EEQ.
