摘要：
This paper presents a preliminary analysis on the impact of ac generators on voltage sags in distribution systems cause by unbalanced short-circuits. The analysis is conducted through numerous electromagnetic transient simulations. Distributed generation systems composed by synchronous and induction machines are considered. The results show that the voltage sags in different system buses are affected due to the presence of ac generators.
