【摘要】 本文给出了求多机电力系统全部机械振模的一种新型迭代算法。该算法针对多机系统机电模型的系统矩阵A的特点,采用一种恰当的迭代方案求取矩阵A的全部特征根(机械振模)。对初始近似迭代点准确选择保证了迭代的收敛性和高效率,同时还可以求取某一指定的机械振模。最后我们给出了一个十机系统的实例计算,结果表明此算法是有效的。更多还原

【Abstract】 In this paper, we introduce a new iterative algorithm of computing mechanical oscillation for multimachine electric power systems. According to the feature of the matrix A of multimachine electric power system, all eigenvalues of the matrix A (mechanical oscillation)and an appointed mechanical oscillaton can be computed simultaneously by means of a suitable iterative scheme. Finally, we give an example of ten-machine systems, computational results show that the algorthm is effective.更多还原
