摘　　要：针对传统配电网规划中缺乏合理的网架接线模式,难以满足预期供电需求的问题,提出了基于供电能力的配网网架规划。以配网供电能力和负荷传输能力为指标建立基于最大负载率的供电能力配网模型,在配网计算模型基础上,对配网互联变电站座数和主变配置,站间互联方式和接线模式进行组合分析,形成网络合理供电架构。模型研究表明:在考虑配网负载率和经济性的条件下,变电站互联数为1~4时,设备利用率能得到提升显著。将模型应用于区域配网网架实例中,在满足配网精细规划的同时,有效提升主变的最大负载能力。Due to the lack of reasonable grid wiring mode in the traditional power supply planning,a network grid planning method based on the power supply capacity is proposed.A power supply capacity distribution capacity model as the index based on the maximum load capacity is established.Based on the distribution network calculation model,the number of seats and main transformer substation configuration,inter-station interconnection mode and wiring mode are analyzed,so as to form a reasonable network power supply structure.The model research shows when considering the load rate and economy of the distribution network,and the interconnection number of substations is 1~4,the equipment utilization rate is improved significantly.The model is applied to the example of the regional network distribution network frame,the result shows the fine planning of the distribution network effectively improves the maximum load capacity of the main distribution network.
