摘要
由于云南某500 kV紧凑型输电线路工程设计条件复杂,不能全线架设同种导线。通过技术和经济比较,针对常规紧凑型、重冰区、I回变电站进出线双回路、II回变电站进出线双回路4种设计条件进行了导线选型。结果对今后其他类似工程具有一定的参考意义。
As the conditions of the design of the 500 kV compact transmission line project in Yunnan are considerably complicated,the same type of conductor can not be adopted for the whole line.This paper presented the study on the conductor scheme selection for the project.Through technical and economical comparisons,selection of conductor schemes were conducted with all the design conditions for the conventional compact transmission line,heavy icing area,single-circuit and double-circuit transmission incoming and outgoing in substations fully considered.The result of the current study can facilitate other similar projects in the future.
