为保证多电压等级电网系统正常运行,提出基于决策树的多电压等级电网故障恢复最优重构算法。首先基于决策树的集成模型识别多电压等级电网故障,并对基分类器进行选取和融合处理,然后利用动态规划模型实现故障恢复最优重构。最后通过对比测试进行验证,经测试该算法可1s内实现故障恢复重构,恢复重构后电网系统负载率标准差较小,可正常运行。

In order to ensure the normal operation of multi voltage level power system,an optimal reconfiguration algorithm for fault recovery of multi voltage level power system based on decision tree is proposed.Firstly,the fault of multi voltage level power grid is identified based on the integrated model of decision tree,and the base classifier is selected and fused.Then,the dynamic programming model is used to realize the optimal reconfiguration of fault recovery.Finally,it is verified by comparative test that the algorithm can achieve fault recovery and reconfiguration within 1s,and the standard deviation of load rate of power grid system after recovery and reconfiguration is small,and the system can operate normally.
