摘要
将多重Ｃａｙｌｅｙ变换法用于电力系统小干扰稳定分析，这种变换有比Ｓ矩阵变换更好的映射特性。同时迭代法被用来计算变换后矩阵的部分按模递减的特征值。５７９阶系统的仿真结果也说明了这种方法的优越性。
Multiple Cayley Transformation is used for small-signal stability assessment of power systems .The method shows better mapping properties than S-Matrix Method does. Simultaneous Iteration is adopted to obtain the eigenvalues of the largest module of the transformed matrix. simulation results on 579 order test system show that the method proposed here is superior to the S-Matrix Method.
