| 摘 要： | 为了提高精细规则的性能,提出一种基于支持样本的线性决策树的规则提取方法。该方法筛选临近稳定边界的支持样本,作为决策树的输入样本,精简了样本数目;提出基于线性分类器的决策树方法,以得到基于组合属性的安全稳定运行规则。在单机无穷大系统和IEEE 39节点系统中的对比研究表明：由于考虑了支持样本的特殊性,用线性组合规则代替单属性规则,减少了计算时间,提高了泛化能力,丰富了规则的物理含义,得到的灵敏度信息可用于辅助决策,在安全稳定精细规则提取中具有应用潜力。

| Abstract: | For the purpose of improving the performance of automatic extracted fine-rule,a method of linear decision tree based on support samples was proposed for rule extraction in this paper.Support samples,which are located in the vicinity of real stability boundary and used as input of decision tree,are selected by distance method.Linear decision tree based on linear classifiers,which were generated by linear transformation,was proposed to obtain integrated attributes operation rules for power system security and... |
