Abstract

This paper presents a method to evaluate the effect of voltage sag in distribution system using the component reliability data of utilities. The proposed method is based on Specified CBEMA curve which is the probability curve of the customers' effect by voltage sag. We carried out the experiment for the customers' sensitive equipments using the test facilities in KERI. The Monte Carlo method and the historical reliability data in KEPCO are used for simulations.
