Impacto de las fallas de alta impedancia en la coordinación tradicional de protecciones de redes de distribución aéreas. Propuesta para mejorar su detección y despeje

Abstract

The present technical study investigates the impact of high impedance faults on the traditional coordination of overhead distribution networks protections, a methodology is proposed to evaluate the economic impact that the distribution company EEQ must confront because of this type of faults that occurs in primary feeders, viable alternatives are proposed, which are protection relays such as the F60 relay, the SEL-451 relay and the RC10 cubicle to complement the capacity of traditional protection systems in the detection and elimination of high impedance faults in primary feeders, the expected annual cost of energy not supplied and the cost to human health are evaluated in economic terms without the implementation and implementation of the system of protection for the detection and / or elimination of high impedance faults.
