| 摘 要： | 本文根据电力系统结构特点探讨了慢同调与弱耦合之间的关系，给出了一种有效的慢同调分区算法，该方法避免了特征值和特征向量的计算，提高了计算速度，因此适用于多机电力系统暂态稳定的分析和计算，并以１５机８３节点电力系统为例，验证了这一方法的有效性。

| Abstract: | In this paper,the relationship between 3low coherency and weak coupling based on structural properties of power systems is investigated and an efficient algorithm of slow coherency-based decomposition is proposed.The computation process of the eigenavalues and eigenvectors of power system is omitted by this approach.Therefore the approach is characterized by its fast speed,and it is suitable for the analysis and computation of transient stability of multimachine power systems.A 15 -machine 83-bus power systemis used as example and the validity of the approach has been verified. |
