| 摘 要： | 首次将隐式重启动Ａｒｎｏｌｄｉ算法应用于大型电力系统低频机电振荡的特征值计算。证明了对重启动Ａｒｎｏｌｄｉ算法、广义Ｃａｙｌｅｙ变换与平移－逆变换等价的条件。通过算例和其他重启动Ａｒｎｏｌｄｉ算法的详细比较，表明隐式重启动Ａｒｎｏｌｄｉ算法收敛迅速、计算可靠且性能稳定，能有效计算大型电力系统中存在的特征值簇。

| Abstract: | In this paper the implicitly restarted Arnoldi algorithm is successfully applied to large power systems for the computation of low frequency electo mechanical oscillation modes for the first time. It is proved that shift invert transformation and generalized Cayley transformation can be equivalent under certain conditions for restarted Arnoldi methods. Comparisons are made with other restarted Arnoldi methods with numerical experiments. Results show that implicitly restarted Arnoldi algorithm is fast, robust and reliable. It can compute eigenvalue clusters that exist in large power systems efficiently. |
