Abstract

In this paper, RCF analysis method which is very powerful to analyze non-continuous systems with switching elements is applied to small signal stability problems. As an effect of switching operations, the eigenvalues of system can be changed and newly unstable oscillation modes may be occurred. Also, changing the ON/OFF time intervals of switching equipments may make the system stable or unstable. As an illustrating example, the oscillation modes of system with different switching time intervals are computed by RCF analysis method.
