摘要
分析了传统无功电压分区中采用的电气距离不足之处,考虑了多个节点之间相互影响的作用,并将这种影响映射成为一个多维的线性空间,在该空间中采用了新的空间距离进行无功电压分区。在此基础上,将电网分区问题转换成高维空间中的聚类问题,并采用模糊聚类算法得到动态聚类图,引入F-统计量来选择最佳分类数。最后,以IEEE39节点系统为例进行电压聚类分区,得到了较好的分区效果。
The shortcoming of traditional definition of electrical distance in power network partitioning is discussed. The effect between power network load nodes is considered, the effect is transformed into a high-dimension space. By this way,the problem of power network portioning can be transformed into a clustering analysis problem in a high-dimension space, fuzzy clustering arithmetic is used to get the dynamic clustering plot.After calculating the statistic F, we can get the final optimal clustering. Finally t...
