Xiangjiaba-Shanghai highest power of UHVDC ready for implementation

Xiangjiaba - Shanghai ±800 kV DC Transmission Project is an integral part of the Jinshajiang River Hydroelectric power transmission project. The UHVDC transmission will be mainly used to transmit the bulk power generated by this project to the Shanghai area in East China. The project interconnects Central power region of China, to which the hydroelectric power plant will be connected synchronously, to the eastern power region of China. The power will be transmitted towards the East during the peak generation period and towards the Centre when water need to conserved in the dam reservoir. The 6400 MW rated power will be transmitted to a distance of 2000km on one single bipolar DC line ±800 kV. The paper describes the detailed features of this project, which is successfully designed and now is going to be implemented.
