Ajuste de relés diferenciales de línea y coordinación de relés direccionales de sobrecorriente en el sistema de subtransmisión de la empresa eléctrica Ambato regional centro norte S.A.

Abstract

The current titling work presents the change of topology in the network: from radial to mesh and a study of adjustment and coordination of protections for the subtransmission system of Electric Company Ambato Regional North Center S.A. By means of the information gathering of the devices installed in the current system, which operates in radial configuration, the electric network was modeled for future operation in mesh configuration, without interrupting the flow of power to final consumers. With the implementation of the protection equipment, adjust the overcurrent relays in each substation of the EEASA and CELEC EP-TRANSELECTRIC and simulate several short-circuit events in the subtransmission network, verify the coordination of the implemented equipment. Comparing the operation times with faults presented in the system, line differential relays were modeled to the outputs of the CELEC EP-TRANSELECTRIC substations, to improve the reliability, reliability and safety in the system.
