摘　　要：提出了在总投资约束下,对地区配电网制订多种节能改造措施组合的综合改造投资规划模型。通过灰关联分析、采样统计和样本改造对比等途径获取灰关联权系数、指标劣度以及改造降损效率等核心参数。在此基础上,在地区电网分层分区管理的模式下,以各项改造投资额为变量,结合投资约束及各项权系数,建立改造投资分配的粗规划模型。算例表明,借助该模型指导节能改造,能充分利用改造资金,显著降低配电网线损水平,并有助于缩小网间线损指标差距,全面提升配电能效,与现有的改造方案相比独具比较优势。A comprehensive transformation investment planning model with multiple investment constraints is proposed for combining various energy-saving measures for the regional distribution network. Such core parameters as gray conneetedness weights, indicator inferiority degrees, as well as the energy saving efficiency of transformation, are obtained by gray relational analysis, sampling statistics and contrasts of sample transformation. Based on the above analysis and in the hierarchical partition management mode of the regional network, a coarse planning model for reform in investment allocation is developed, with investment amounts as variables and by referring to various investment constraints and weights. An example shows that, with the energy saving model as guidance, the reform fund can be made full use of, the distribution network line loss is markedly lowered, and the line loss gaps between nets effectively reduced, while the energy efficiency of distribution is enhanced in an all round way. Compared with existing rehabilitation programs, the planning model boasts unique comparative advantages.
