基于信息熵最优约简算法的电网故障诊断模型

介绍粗糙集理论及信息熵约简方法,应用粗糙集理论对电网故障样本数据进行分析统计,建立决策表,采用信息熵约简算法对其进行条件属性约简,得到一组最小知识系统,再用粗糙集值约简方法对其进行简化,得到一组故障诊断的最小决策规则集,结合模型进行分析,证明该方法简便、快速、有效。

Fault Diagnosis Model of Power Network Based on Information Entropy Reduction Algorithm

This paper utilizes the information entropy algorithm based on rough set theory to solve the problem of fault diagnosis for power network.Based on rough set theory,this paper analyses the data of power network faults and set up a decision table,and then uses the information entropy algorithm in conditional attributes reduction to gain a reductional system.Subsequently,this paper reduces the new system using the method of rough set reduction,produces a group of minimal decision rules.Accordingly,computing sp...
