Xiangjiaba–Shanghai HVDC system

The HVDC Xianjiaba -Shanghai is a high-voltage direct current transmission line ( HVDC) in China between the hydroelectric power plant at the Xiangjiaba Dam on the border between the provinces of Sichuan ( Yibin ) and Yunnan ( Shuifu ) and in eastern China located metropolis of Shanghai. Begun in April 2007 and completed in July 2010 line has a length of 2070 km transmission capacity of 6400 MW, which corresponds approximately with as of 2010 one third of the peak consumption of the city of Shanghai, and is operated by the State Grid Corporation. At the time of commissioning, she was the world's longest HVDC line and after the HVDC Yunnan - Guangdong's second bipolar HVDC system is China which operated in the final with an operating voltage of ± 800 kV.

The western Fulong converter station and the beginning of the line is about 10 km from the Xiangjiaba dam removed (coordinate: 528.5463895604.417778528 ° 32 ' 47 " N, 104 ° 25' 04" O28.546388888889104.41777777778 ) and is powered by four three-phase systems, each with 500 kV powered by the hydroelectric plant of the dam. Built by Siemens plant includes ten converter transformers.

The eastern and built by ABB converter station Fengxia and end of the line is located about 45 km south- east of Shanghai (coordinate: 530.9255565621.771111530 ° 55 '32 "N, 121 ° 46' 16" O30.925555555556121.77111111111 ) and feeds the electrical energy via a three -phase current systems of 500 kV in the public electricity grid in the Shanghai area.
