Abstract :
This paper presents an analysis of the impact of induction generators on voltage sag in distribution systems caused by unbalanced faults. It was analyzed single line-to-ground faults (SLGF´s) and line-to-line faults (LLF´s). The analysis is conducted through electromagnetic transient simulations. Moreover, the impact of different connections of the transformer between the generator and the power system was also investigated. The results show that the voltage sags in different system buses are affected due to the presence of induction generators.
