The Yunnan–Guangdong HVDC is a
Zengcheng in Guangdong, China. It is the first HVDC link in the world operating at a transmission voltage of 800 kV.[1] The transmission line is operated by China Southern Power Grid. In 2007, the order to supply the system was awarded to Siemens Energy.[2] The first pole was put into operation in December 2009 with the second pole to follow in June 2010.[3]
The transmission system has a transmission capacity of 5,000 MW and a rated DC current of 3,125 A. It has a total length of 1,418 kilometres (881 mi).[4] It transmits electricity from the hydropower plants in the Yunnan to the Guangdong, including cities of Guangzhou and Shenzhen.[1]
Yunnan–Guangdong HVDC shares the grounding electrode together with HVDC Guizhou - Guangdong II at Linwu ( coordinates: 23°44′48″ N 113°17′09″E ).
