在特高压交流试验示范工程1 000 kV南阳站扩建工程中加装了1 000 kV串补装置，该串补装置平台尺寸、质量、安装高度等方面远大于500 kV串补平台，平台安装要求较高，安装难度较大。总结了1 000 kV晋东南侧串补平台的现场安装经验，可为特高压工程变电站现场的标准化施工提供参考。

During the extension project of UHV AC testing demonstration engineering 1 000 kV Nanyang substation, a 1 000 kV series compensation(SC) device platform is installed, of which the size, quality, installation height etc. are more higher than those of 500 kV one. The demand of platform installation with great difficulty is very high. In this paper, the 1 000 kV SC platform installation experiences of Jindongnan side are summarized, providing references for construction standardization of UHV substation.
