Metodología para la planificación y control de la ejecución de mantenimientos preventivos y correctivos de líneas de subtransmisión

Abstract

The present degree work proposes a methodology for the planning and control of the execution of preventive and corrective maintenances of subtransmission lines through the implementation of the method of Gravity, Urgency and Tendency "GUT" that will allow to define priorities for the attention of problems caused in subtransmission lines. The definition of the subtransmission line, its constituent elements and its electrical and mechanical parameters are described. Additionally, the types of maintenance are shown, the activities that are carried out in the execution of maintenance at national and international level. The responsibilities of the authorities of the electricity sector concerning the execution of maintenance in generation, transmission and distribution systems derived from the Organic Law of the Public Electric Power Service (LOSPEE) are mentioned, as well as regulations that are issued by the Agency for Regulation and Control of Electricity (ARCONEL). According to the information available from the ARCONEL, it is indicated the infrastructure of the electricity sector, the electric power quality indices of the distribution companies in a period from 2008 to 2016. The responsibilities of the operation and maintenance of subtransmission lines are identified in the Quito Electric Company and in the Ambato Regional Central North Electric Company.
