HVDC Yunnan – Guangdong
The HVDC Yunnan – Guangdong is a high-voltage direct current transmission line (HVDC) in China between the city of Chuxiong in Yunnan Province and the eastern city of Zengcheng near Guangzhou in Guangdong Province . The 1418 km long line is operated by the China Southern Power Grid and is the first bipolar HVDC that will be operated with an operating voltage of ± 800 kV in the final stage .
Construction began in 2007, the HVDC was put into monopolar trial operation in December 2009, and full bipolar operation began in June 2010. The cable manufacturer is Siemens AG .
The HVDC is in full operation for a transmission capacity of 5 GW designed, the electric current per phase amounts to 3125 A . The two converter stations consist of four converters of 400 kV each. The electrical direct current is transported from Yunnan, where the HVDC is fed via four three-phase AC lines with 500 kV each from two hydropower plants at the Xiaowan Dam and the Manwan Dam , to the industrially developed metropolitan area of Guangzhou .
