RXHK Awarded World's Largest VSC HVDC Converter Contract 


On 30th August 2018 China Southern Grid announced the contracts it had awarded to build the hybrid HVDC scheme to link the WuDongDe hydro-electric power plant in Yunnan province to the load centres in Guangdong province.

This mega-HVDC scheme is named "KunLiuLong", the combination name of the three converter stations. "Kun" refers to Kunming North Converter Station (LCC 8GW). "Liu" refers to Liuzhou North Converter Station (VSC 3GW). "Long" refers to Longmen Converter Station (VSC 5GW). The DC voltage for the scheme is 800kV.

Following on from its successful type testing of a 5GW 800kV VSC HVDC valve in June 2017 RXHK was awarded in this announcement by China Southern Grid a contract to design, supply and commission a 5GW 800kV converter for the Longmen converter station. When operational this will be the world's largest VSC HVDC converter.
