Reconfiguración y soterramiento parcial de la línea de subtransmisión a 69 kV desde la S/E Ambato de Transelectric hasta las S/E’s de distribución Loreto y Oriente de la EEASA y adecuación de la S/E Loreto

Abstract

The present technical study focuses on the redesign of a three-phase power line in the 69 kV EEASA subtransmition system. This line has an approximate length of 3.5 km and connects the Ambato of Transelectric S/Es and the Oriente of the EEASA, at 1.2 km from this there is a direct derivation of circuit in the 069 tower of the EEASA, without equipment cutting or sectioning and reaches the S / E Loreto, this derivation in the form of "T" produces that the Oriente and Loreto S/Es operate radially and in events of failure the S / E Loreto stops supplying power, which is a problem of high magnitude because it provides power to important areas of the Ambato city. The circuit in the form of "T" is eliminated and modified to a double circuit, changing the operation system of the S/Es from radial to network, and the total system of the EEASA can operate in a loop. Of the double circuit, the first will be the aerial installed at present and the second will consist of two stages, one aerial and the other underground. The Loreto S/E must be adapted so that it operates with the double circuit without any inconvenience. In order to evaluate the results of this study the reliability of the system will be analyzed and the improvement of the indicators will be sought when going from a radial system to a ring system, finally a price analysis in dollars is shown, to estimate the cost of the execution of the study.
