Análisis causa raíz de fallas en reconectadores automatizados acoplados a la red de distribución de Centrales Eléctricas del Norte de Santander S.A. E.S.P.

Abstract

Currently the CREG (Commission for Regulation of Energy and Gas) seeks to expand the coverage of electricity service to 100% of Colombian households, this will be carried out progressively increasing the electrical infrastructure of the SIN (National Interconnected System), updating and adding equipment that guarantees a good quality of service by network operators. The main problem in terms of quality of service is the unscheduled interruptions suffered by the electrical system and which negatively affect the average quality indices SAIFI and SAIDI; these indicators measure the reliability of the system and determine the remunerations of the distribution of electric power that network operators may or may not have. Reclosers are one of the main equipment proposed by CREG to mitigate the duration and frequency of power system interruptions; so much so, that it requires the OR according to the CREG 015 of January 2018 to modernize equipment, have a number of reclosers coupled to its electrical structure and carry out periodic preventive maintenance. The main objective of this study is to determine the root cause of the faults suffered by the automated reclosers in the distribution networks, with the purpose of creating strategies and solutions that guarantee their functionality and constant operation in the electrical network. The data that will be analyzed will be taken from the monthly events reports from 2013 to 2019 of CENS S.A E.S.P. in which it is evidenced: the duration, the cause, the date, the number of affected users, the regional one, the feeder (associated circuit), the affected transformer code, the starting code and the objective of the failure; necessary referents for the analysis and determination of problems that may prevent a correct work of these devices.
