World's First Multi-Source DC Project in Jiangsu Completes Phase II, Boosts Cross-River Power Transmission
On February 12, the second - phase project of the ±200 kV DC power transmission project from Yangzhou to Zhenjiang in Jiangsu, which is the world's first multi - source commutated DC power transmission project and China's first AC - DC hybrid cross - river project, was completed and put into operation.
The project's transmission line is about 228 kilometers long, with a transmission capacity of 1.2 million kilowatts. It passes through three cities (Huai'an, Yangzhou, and Zhenjiang) and seven counties. Among them, a 47 - kilometer new - built DC transmission line is erected on the same tower as the 500 kV AC line, and two new converter stations are built. Without adding a new cross - Yangtze - River power transmission channel, the original cross - river power transmission capacity has been
