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.

关 键 词:评价  高中压  配电网  鱼骨图  曲线拟合

Abstract:Existing distribution network evaluationsystems do not cover high-and medium-voltage distributionnetworks, so they are not suitable for lateral contrast amongurban distribution networks. For this reason, a comprehensiveevaluation system that is generally suitable for urbandistribution networks is proposed. Firstly, starting from thedemand of stakeholders of power networks and by use offishbone diagram, key elements impacting the construction ofdistribution network are analyzed and a comprehensiveevaluation index system that can overall reflect thecharacteristics of distribution network construction isestablished; then the index weights following unified standardare set by Delphi; finally by means of setting index evaluationcriteria the curve fitting of the index evaluation criteria isperformed to obtain index scoring function, thus acomprehensive evaluation system for urban distributionnetwork that covers high-and medium-voltage distributionnetworks and can be used for the lateral comparison amongdifferent distribution networks is formed. Results of computingexamples show that the proposed evaluation system canreasonably reflect the overall development level of distributionnetworks and laterally compare superiors and inferiors ofdifferent distribution networks, and find out the weak links ofeach distribution network, therefore the evaluation resultscould be available for reference to the planning, constructionand development of distribution networks.
Keywords:evaluation  high and medium voltage  distribution network  fishbone diagram  curve fitting
