Since 1970s, number of small signal stability studies for large power systems have been published and significant effort has been extended to reduce the computation time and to obtain a specific set of eigenvalues. And now much work is still under research.
Recently more attention has been paid to parallel processing and great effort has been made to solve power problems.
This paper proposes a parallel algorithm using SI method which is suitable for parallel eigen value analysis.
To confirm the effectness of proposed algorithm implemented on a message-passing hyper-cube type parallel computer, test calculations were performed using some kinds of practical power system. The results show that the proposed algorithm is 30_??_50 times faster than single CPU calculation.
