Análisis técnico y económico para la utilización de conductores semiaislados en redes aéreas de media tensión en los sistemas de distribución

Abstract

The entities in charge of carrying out the construction, maintenance and operation of the electrical distribution systems are the distribution companies and in the provinces of Azuay, Cañar and Morona Santiago, the entity in charge of supplying electricity to the different consumers is the Empresa Eléctrica Regional Centrosur ( E.E.R.C.S.). The E.E.R.C.S builds and designs the distribution networks through aerial, mixed and underground systems. Each one of these systems presents advantages and disadvantages, being a disadvantage of the aerial systems their low reliability while in the underground networks their disadvantage lies in the high cost for their construction. The objective of this degree work is to carry out a technical and economic analysis of the semi-insulated overhead network in comparison with the conventional bare conductor network used in the medium voltage network, in order to motivate the E.E.R.C.S to incorporate this type of network. in existing and future projects. In this titling work, five chapters will be developed, with chapter 2 being the analysis of the types of electricity distribution networks, chapter 3 a technical analysis of the medium voltage semi-isolated overhead network. In chapter 4 the design and economic analysis of a section of the medium voltage network with a semi-insulated and bare system is carried out; and finally in chapter 5 the conclusions and recommendations that will allow establishing the viability of the application of the semi-insulated cable in medium voltage overhead networks are presented.
