摘　　要：减少配电网运行过程中不必要的损耗,实现我国电力系统的节能降耗,具有一定的现实指导意义。本文通过配电网的运行特点和影响因素,由配电网负荷、配置、架构三个指标建立经济性评价指标体系的不同层次,利用层次分析法进一步定量分析,对判断矩阵的特征向量加权求和,得出最终权重。再建立基于AHP的可拓评价模型,用关联函数量化节域物元、经典域物元、待评物元,得到最终评价结果。最后由评价结果采取不同相应措施提高电网运行的经济性。It is practical significance to reduce unnecessary losses in the operation process of distribution network and realize energy saving and consumption reduction of China's power system.Through the operation characteristics and influencing factors of the distribution network,this paper establishes different levels of the economic evaluation index system by the three indexes of load,configuration and architecture of the distribution network,and makes further quantitative analysis by using the hierarchical analysis method(AHP),weights the feature vector of the judgment matrix,and obtains the final weight.Then the extenizable evaluation model based on AHP is established,and the association function is used to quantify the domain element,the classical domain element and the pending evaluation element,and the final evaluation results are obtained.Finally,different corresponding measures are taken to improve the economy of power grid operation.
