The 3-phase 4-wire voltage sag generator based on abc algorithm

Abstract

Voltage sags from fault or ground fault are the most prevalent disturbances in electrical power system. A recent survey attributes them to 92% of all disturbances. This paper presents the simulation and experimental of 3 phase 4 wire voltage sag generator based on three dimensions space vector modulation in abc algorithm to produce voltage sag for testing electrical equipment. The experimental results can be used as an initial phase in process of designing a 3 phase 4 wire voltage sag generator. ©2009 IEEE.
