±800kV换流站通用设计研究与应用

Research and Application of General Design for ± 800kV Converter Station

介绍了±800 kV换流站通用设计编制的目的、输入条件和主要技术原则,并按照换流站功能区划分为换流场、直流场、交流滤波器场、站用电、接地极5个基本模块。重点分析了±800 kV换流站设计的主要技术方案,对电气主接线形式、布置方案及优化要点等进行了详细的说明,提出了适应不同外部条件的15个标准化模块方案,为后续特高压换流站设计工作提供参考。

This paper introduced the objective, input conditions and main technical principles of the general design for ± 800 kV converter station. The functions of converter station were divided into 5 basic modules, including converter field DC field, AC filtering field, auxiliary power and earth electrode. Then this paper mainly analyzed the main technical scheme of the design for ±800 kV converter station, and explained the main wiring forms, layout scheme and optimization points in detail. Finally, this paper proposed 15 module programs that could adapt to different external conditions, which could provide references for the following design of UHV converter station.
