An application of predictive reliability analysis techniques in Brazil’s northeast distribution networks

Presently, electric utilities are facing an increasing number of complaints about distribution system reliability. This fact has been caused by the growth of sensitive loads in all the customer sectors. Due to this, power distribution utilities are applying predictive reliability assessment (PRA) in the distribution system planning to achieve the customers reliability requirements. This paper has its objective as the description of the application of the PRA technique in a feeder of a distribution utility located in the Northeast of Brazil. The results obtained with the proposed PRA model allowed the identification and diagnosis of critical areas and vulnerabilities in the distribution feeders.
