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 firing angles of switching equipments may make the system stable or unstable. As an illustrating example, the oscillation modes of the system with different firing angles are computed by the RCF analysis method.
