Representatives from UK’s National Grid have been to China to witness a solution RXPE (RXHK since 2017) developed for the world’s first multi-terminal VSC-HVDC system in operation.
The team visited the Sucheng converter station, where they were introduced to RXPE’s 200MW HVDC valve and control package. RXPE also provided station controls for all three terminals of the Nan’ao VSC-HVDC project as well as the overall multi-terminal control system.
The Sucheng converter station has been operational since December 2013. Following its success, China Southern Grid awarded RXPE a contract for a 1GW 350kV converter, to be commissioned in summer 2016.
