Distributed generation impact on voltage sags

Abstract

This paper presents the impact of the distributed generation on voltage sags caused by faults. Symmetrical and asymmetrical faults are simulated at sub-transmission and distribution lines. Voltage sags are monitored at buses where sensitive end-users are connected. Faults were simulated using ANAFAS software. In order to run several cases a Java routine was implemented. This solution let the automatic simulation of cases including different fault locations and fault impedances.
