摘　　要：现有配电网评价体系未能涵盖高中压配电网,不适于城市配电网进行横向对比,为此提出了具有普遍适应性的城市配电网综合评价体系。首先从电网利益相关者需求出发,利用鱼骨图法分析影响配电网建设的关键要素,建立全面反映配电网建设特点的综合评价指标体系;其次,采用德尔菲法建立统一标准的指标权重;最后,通过设定指标评价判据并对指标评价判据进行曲线拟合得到指标评分函数,从而形成能够用于不同配电网横向对比且涵盖高中压配电网的城市配电网综合评价体系。算例结果验证了该评价体系能够合理反映配电网的整体发展水平,横向对比不同配电网的优劣,并能找出各个配电网的薄弱环节,为配电网的规划、建设和发展提供参考。Existing distribution network evaluation systems do not cover high- and medium-voltage distribution networks, so they are not suitable for lateral contrast among urban distribution networks. For this reason, a comprehensive evaluation system that is generally suitable for urban distribution networks is proposed. Firstly, starting from the demand of stakeholders of power networks and by use of fishbone diagram, key elements impacting the construction of distribution network are analyzed and a comprehensive evaluation index system that can overall reflect the characteristics of distribution network construction is established; then the index weights following unifed standard are set by Delphi; finally by means of setting index evaluation criteria the curve fitting of the index evaluation criteria is performed to obtain index scoring function, thus a comprehensive evaluation system for urban distribution network that covers high- and medium-voltage distribution networks and can be used for the lateral comparison among different distribution networks is formed. Results of computing examples show that the proposed evaluation system can reasonably reflect the overall development level of distribution networks and laterally compare superiors and inferiors of different distribution networks, and find out the weak links of each distribution network, therefore the evaluation results could be available for reference to the planning, construction and development of distribution networks.
