高海拔地区750 kV变电站750 kV侧HGIS配电装置布置方案对比研究

Comparative Study on Layout Scheme of 750kV HGIS Distribution Unit in 750kV Substation at High Altitude

依托乌图(昆仑山)750 kV变电站工程,对高海拔地区(3000 m)750 kV侧HGIS配电装置C字型布置方案与一字型布置方案进行对比分析。从出线规划、元件安装检修、占地面积、构架及布置尺寸、工程投资、运行安全等方面进行技术经济比较,得出750 kV侧HGIS配电装置C字型布置方案,具有较好的技术优势及经济效益。乌图(昆仑山)750 kV变电站工程为国家电网公司首批模块化建设2.0版示范工程,目前已进入施工安装阶段。

Based on Utu(Kunlun Mountain)750kV substation project,the C-font layout scheme and 1-font layout scheme of 750kV HGIS distribution unit in high altitude area(3000m)are compared and analyzed.Through the technical and economic comparison from the aspects of outlet planning,component installation and maintenance,floor area,frame and layout size,project investment,operation safety and so on,it is concluded that the C-shaped layout scheme of the HGIS distribution unit on the 750kV side has better technical advantages and economic benefits.Utu(Kunlun Mountain)750kV substation project is the first batch of modular construction 2.0 version demonstration project of State Grid Corporation,which has entered the construction and installation stage.
