陕西330kV电网线路导线截面的选择

Selection of Tranmission Line Conductor Cross Section in 330kV Power Grid

随着用电负荷增长、电网规模扩大、330kV变电站数量增加、容量增大,330kV电网初期线路导线选择的条件已发生较大变化,有必要研究330kV电网主网架导线截面系列化和标准化问题。以典型电网结构为基础,分析了电网输电能力要求,根据导线允许载流量,提出了330kV电网导线截面选择推荐意见,可为电网规划和工程设计提供参考。

With the electricity load growth,power grid expansion,increased number of 330kV substation,increased capacity,grid conductor cross section selection condition has changed.It is necessary to study the serialization and standardization of grid conductor cross.Based on typical grid,the power transmission capacity requirement is analyzed.According to the conductor allowable current,the conductor cross section selection of 330kV power grid is put forward which can provide references for grid planning and design.
