因不了解外部环境的变化,错误预测用电需求而造成投资浪费、变电站重复建设、线路负载过低、资产负债率高等问题时有发生;同时缺少有效的项目整合方法,导致“多头报送、重复投资、重复停电”的现象。为了使配电网建设项目的投资计划更加精确,对症供电地区的外部实情,同时减少重复投资,缩短停电时间,推动电网建设项目的精益化管控,本文首先设计了基于外部环境对地方供电单位配电网投资决策优选模型,其次通过设计地方供电单位配电网建设项目投资决策辅助系统,在系统中嵌入投资决策优选模型,实现配电网建设项目投资优选;同时嵌入项目整合方法,实现项目的去重整合和深度整合,优化投资安排。
Because they do not understand the changes in the external environment, mistakenly forecast the power demand caused by waste of investment, redundant substation construction, line load is too low, high debt ratio problems occur at the same time the lack of effective project integration methods, resulting in , Repeated investment, repeated blackouts "phenomenon. In order to make the investment plan of the distribution network construction project more accurate, the external reality of the sympathic power supply area, reduce the repeated investment, shorten the blackout time and promote the lean control of the power grid construction project, this paper first designs the local power supply unit Second, through the design of local power supply unit distribution network construction project investment decision support system, embedded in the system of investment decision optimization model, to achieve distribution network construction project investment optimization; at the same time embedded project integration methods to achieve the project De-consolidation and deep integration to optimize investment arrangements.
