±800kV特高压直流输电标准体系及主设备标准的探讨

Investigation of ±800 kV UHVDC Transmission Standard System and the Standards for Main Equipments

目前国内外尚未有±800 kV直流输电设备和设计标准体系。基于我国在特高压直流技术理论研究和工程实践,兼顾已有的±500 kV标准,文章探讨了±800 kV特高压直流输电标准体系的构建原则,并着重介绍了在国际上先行的±800 kV主设备相关标准,包括换流变压器、换流阀、平波电抗器、套管和绝缘子。

A whole scheme of design standars for ±800 kV UHVDC transmission is not yet available in the world.Based on the theoretical study and practic,and taking the exist standards for ±500 kV voltage level into account,this paper investigates the architecture principle of standards for ±800 kV UHVDC transmission,especially with focus on the standards for its main equipments such as converter transformer,converter valve,smoothing reactor,bush and insulator.All these proposed standards are pioneers in the world.
