Abstract :
In this paper, dynamics of voltage stability in a multimachine system is investigated. To obtain dynamics of voltage stability, static and dynamic techniques are used. This study shows that the use of static approach is limited in determining the dynamic behavior of voltage stability. Results of time domain simulation are presented to clarify the phenomenon of voltage instability. The results show the importance of maintaining the voltage control capability of generators. It has been shown that the dynamic characteristics of load influence the dynamics of voltage stability.
