A Comprehensive Evaluation System of Urban Distribution Network

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.
