220kV双回路转角塔上“π”接110kV双回路线路的优化设计

Design Optimization of Double-circuit 110kV Line ‘π’ Branching from a Double-circuit 220kV Angle Tower

根据电网供电的需求,要将某段220kV双回线路临时降压110kV运行。下面介绍经过技术经济比较选出的方案,将某220kV双回路转角塔"π"接110kV双回路线路,解决用110kV临时供电的设计,供同类工程参考。

In view of the power supply of the network, it needs to use a section of double-circuit 220kV transmission line down grading into 110kV running. Having made technical and economic comparison, a scheme of using certain 220kV double-circuit angle tower to accomplish ＇π＇ branching of 110kV is selected to fulfill the need of temporary supply. The design is worth as reference to similar engineering.
