摘　　要：为了提高配电网建设投资效益,根据高压配电网的特点,以负荷特性、负荷布局、电网发展程度、网架结构4个电网基本特征为基础,构建了高压配电网运行效率评价指标体系。采用相关性分析方法建立了配电网特征指标和电网运行效率指标之间的关联关系,进而提出了基于相关性分析的高压配电网运行效率评价方法。以某地县辖配电网为例对所提方法进行验证,评分结果表明所提方法能够反映高压配电网的实际运行情况,数据易于获取,符合实际工作需要,能够指导高压配电网规划工作。To improve the investment benefit of the power grid construction,this paper discusses establishment of an efficiency index for HV distribution networks from four aspects of load characteristics,load density,development margin and network structure.The correlation between distribution network characteristic index and power grid operation efficiency index is established by correlation analysis method,and then an evaluation method based on the correlation analysis is put forward.The proposed method is validated taking a county distribution network as an example,and the evaluation results show that the proposed method can reflect the actual operation of HV distribution network,the data is easy to get and in line with the actual need of work,and can guide the planning of HV distribution networks.
