摘 要:为打造更高水平的城市配电网,探索典型接线模式的评估及选型方法成为必然。首先基于配电网可靠性、经济性、适应性等发展目标,建立典型接线的双层评估指标体系,并构造隶属度公式对正、反向指标进行标准化处理;然后提出E-熵权法改进底层指标赋权,有效避免了权值极端“分化”,由此对上海“钻石型”接线等6类典型接线模式的目标指标进行了百分制评估;最后由层次分析法对目标指标赋权,并结合数据包络分析法的超效CCR模型(supper effectiveness Charnes-Cooper-Rhodesmodel,SE-CCR)构建指标体系的效率转化指数,进一步离散各接线模式的综合评分,最终通过推荐系数为选型提供决策支持。In order to build a world-class urban distribution network,it has become a trend to explore the methods of the evaluation and selection of the typical wiring modes.First,based on the reliability,economy,adaptability and other goals of the distribution network,a two-layer evaluation index system is established,and a membership formula is constructed to standardize the forward and the reverse indicators.Then,the E-entropy weight method is proposed to improve the weight of the underlying indicators,which effectively avoids the differentiation.A percentile evaluation of the target indicators for the six typical connection modes like the Shanghai "Diamond" mode is conducted.Finally,the target index is weighted by the AHP method,and the efficiency conversion of the index system is constructed through the SE-CCR model,further discretizing the comprehensive score of each connection mode.The recommendation coefficient is used to provide the decisive support for the selection.
