Diseño construcción de la línea de subtransmisión a 69 kv songa.

Abstract

The following document describes the design of a Subtransmission line at a voltage level of 69 kV, through which the electric demand requested by the shrimp exporting company "Songa", located to the south of the city of Guayaquil, which has built a substation that operates at a voltage level of 69kV with a capacity of 3.75MVA, will be supplied with electric energy to the new shrimp packing plant that belongs to that company. The design methodology of the line that will feed the substation on the premises of the company "Songa", includes the analysis of all the phenomena that affect the line, making a description of each of them, both electrical and mechanical phenomena. For the present project were taken into account the rules of EX - INECEL and the regulations that are stipulated by the electricity supplier, Business Unit CNEL EP - Guayaquil, and the municipal ordinances that currently govern the city of Guayaquil. The design of the subtransmission line involved the resolution of mathematical equations for obtaining electrical parameters such as resistance, inductance, capacitance, conductance and mechanical parameters such as arrows and the stresses exerted in each bay of the line. These results were contrasted with those obtained through the application of transmission line design software.
