摘要
针对城市110 kV电网建设和规划中存在的问题,分析了变电站主变压器容量、台数的选择及变电站的典型接线方式,引入了一种基于全年小时最大负载有功功率的变压器容量及台数的选择方法,阐述了变电站线损控制及设备技术原则,提出了一种新型110 kV变电站主变容量、台数及接线方式的选择方案,为城市110 kV电网规划建设提供了指导性建议。
Aiming at the problems of grid construction and programming for 110 kV city distribution network,this paper analyzes selection of capacity,numbers and typical grounding mode for main transformer.Based on annual maximal load active power per hour,an approach of choosing capacity and numbers for main transformer is presented in this paper.The line loss control and principle of equipment technology for substation is represented.A new selection scheme of capacity,numbers and connection mode for main transformer...
