Optimización de la confiabilidad mediante la reconfiguración de circuitos primarios en la subestación Quevedo de CNEL EP. Unidad de negocio Santo Domingo.

This research work deals with the reliability analysis in the feeders belonging to the Quevedo substation of CNEL EP, in order to establish the circuits with the highest number of electrical power interruptions to submit them to a reconfiguration analysis, using historical data from the last three years, where Pareto analysis is used to determine the percentage of interruptions that most affect each feeder. As a starting point, the information is classified by type of failure and duration, to determine the rate of failure and repair, availability (A) and unavailability (U) of the feeders, data with which it is possible to calculate the failure rates. reliability. From these results, the reconfiguration of circuit 6 is analyzed, since it presents the lowest indices. Using the Monte Carlo simulation in the MATLAB software package, it will be possible to determine the failure times and repair times in each section of the feeder. Applying the theory of graphs, the section with failure (disconnected) and the possible reconnection from neighboring nodes are determined, considering as a restriction the chargeability of the lines, that the repair time is less than the maneuvering time for a possible reconnection. This will allow new reliability indices to be calculated before and after reconfiguration during a prudent analysis time, allowing the optimal path to be identified.
