HVDC Xianjiaba – Shanghai

from Wikipedia, the free encyclopedia

The HVDC Xianjiaba-Shanghai is a high-voltage direct current transmission line (HVDC) in the People's Republic of China between the hydropower plant at the Xiangjiaba Dam on the border between the provinces of Sichuan ( Yibin ) and Yunnan ( Shuifu ) and the metropolis of Shanghai in eastern China . The line, which began in April 2007 and was completed in July 2010, has a transmission capacity of 6,400 MW over a length of 2070 km  , which as of 2010 corresponds to about one third of the peak consumption in the metropolis of Shanghai, and is operated by the State Grid Corporation . At the time of commissioning, it was the world's longest HVDC line and after the HVDC Yunnan – Guangdong it is the second bipolar HVDC system in China which will be operated with an operating voltage of ± 800 kV in the final stage  .

The western converter station Fulong and the beginning of the line is approx. 10 km away from the Xiangjiaba dam (coordinate: 28 ° 32 ′ 47.0 ″  N , 104 ° 25 ′ 04.0 ″  E ) and is powered by four three-phase systems with 500 kV fed by the dam's hydroelectric power station. The system built by Siemens includes ten converter transformers . ! 528.5463895604.4177785

The eastern converter station Fengxia and the end of the line, built by ABB , is located approx. 45 km south-east of Shanghai (coordinate: 30 ° 55 ′ 32.0 ″  N , 121 ° 46 ′ 16.0 ″  E ) and feeds the electrical power Energy is fed into the public power grid in the greater Shanghai area via three three-phase systems of 500 kV each. ! 530.9255565621.7711115
