Abstract

Voltage sag is one of the most common power quality disturbances in electric networks. It is necessary to investigate voltage sag due to consumers’ vulnerability. Faults are the main cause of voltage sags in distribution networks. Fault in distribution networks according to its specifications (its location, duration and time) can cause an interruption or a voltage sag at the nodes of the network. By making random faults, the voltage sag in such networks can be investigated. In this paper, the effect of protective devices performance such as recloser and fuse in voltage sag due to distribution network faults using MATLAB Software has been evaluated.

 

Key words: Voltage sag, fault, recloser, fuse.
