Zurich, Switzerland, January 11, 2010 – Power and automation group ABB performed a successful open-line test for Pole 1 of the 800 kV ultrahigh-voltage direct current Fengxian converter station in Shanghai.
In cooperation with State Grid Corporation of China, this test was accomplished in a record time of two years from receiving the order, a year ahead of schedule.
The ±800 kV Xiangjiaba-Shanghai HVDC link will transmit 6,400 MW of power from the Xiangjiaba hydropower plant, located in the southwest of China, to Shanghai, China’s leading industrial and commercial center, located more than 2,000 kilometers away.
The voltage level and transmission capacity record is presently held by the 600 kV Itaipu transmission line in Brazil, which was also delivered by ABB.
The efficiency of the Xiangjiaba-Shanghai transmission line will be more than 93 percent, with transmission losses being restricted to less than 7 percent.
This would enable power supply for an additional 1 million people in China every year as compared with the 500 kV HVDC systems in use there.
ABB’s scope of delivery includes fourteen 400 kV converter transformers and fourteen 800 kV converter transformers, of which ten will be delivered from Sweden and the rest manufactured locally in partnership with TBEA in Shenyang, with ABB components and technology.
Other key products include thyristor valves, direct current switchyard equipment, measuring equipment for the alternating current switchyard and the newly developed DCC800 HVDC control system.
