摘要
南澳多端柔性直流输电示范工程(简称南澳柔直工程)是世界上第一个VSC-MTDC工程。首先介绍了模块化多电平换流器的拓扑结构,然后介绍了南澳柔直工程的系统集成设计方案。南澳柔直工程换流站采用单换流器双极接线方式,以交直流并联、纯直流或STATCOM方式运行。该工程本期为采用树枝式并联接线的三端直流输电系统,远期将建成四端柔性直流输电系统。还介绍了南澳柔直工程主设备参数、保护配置和系统三端启动过程。
Nan'ao VSC-MTDC Demonstration Project is the first VSC-MTDC project in the world. The MMC (modular multilevel converter) topology and the integrated system design scheme of Nan'ao VSC-MTDC project are introduced. The converter station of the project adopts a single converter and bipolar connection, and is able to operate in the modes of AC/DC paralled, DC only and STATCOM. The present project consists of three terminals with branch type parallel connection, and in the near future, it will be upgraded into a system of four teminals. The main device parameters and protection configuration of the project as well as the starting process of the three converter stations are also presented.
