摘　　要： 选取重要母线的节点相角差作为候选属性,构建出决策树,将其用于电压稳定分析,并提出了基于决策树的电压稳定性分析方法。以6节点系统为实例在Powerworld中进行了仿真计算,得到了满意的结果。 A decision tree based method is presented to model and analyze voltage stability of power systems in this paper.Decision tree is used to model voltage stability of power systems,and a classification method for analyzing the state of power systems is studied.The simulation results carried out illustrate that the classifying errors of voltage stability of power systems is less than 8.33% when decision tree based method is applied.In the proposed method,much less time in training for fuzzy-neural network is needed because few examples are used.An example of a 6-nodes system is given to verify the proposed model and method.
