| 摘 要： | 给出了一种能识别电力系统同调机群的模糊聚类方法。首先采用最大－最小方法对线性化后的系统状态矩阵进行标定，得到反映机组间动态相关程度的模糊等价关系矩阵，然后采用模糊聚类方法识别同调机群。最后给出了10机和24机两个试验系统同调机群识别结果，并通过特征根计算证明了此方法的有效性。

| Abstract: | A fuzzy clustering method for recognizing coherent generator groups in power system is proposed in this paper. First, a fuzzy equivalence relation matrix is formed by applying maximum minimum algorithm to the linearized state matrix of the power system. Then the coherent groups are recognized by use of fuzzy clustering method. At last, the results of coherent groups recognition for 10 machine and 24 machine test system are given and the effectiveness of fuzzy clustering method is demonstrated by eigenvalue calculation. |
