China installs world’s largest offshore converter station [free access]

August 11, 2021

According to reports, the world’s largest offshore converter station, which weighs 22,000 tonnes and is as tall as a 15-storey residential building, has recently been installed at the Jiangsu Rudong offshore wind project being developed by Chinese state-owned utility China Three Gorges Corporation (CTG). The project is the first intertidal offshore demonstration wind project in the country. The Rudong converter station is the first offshore ±400 kV wind power flexible direct current (DC) transmission project in China.

 

The station will be used to collect 1,100 MW of electric energy from three wind farms, namely the 300 MW H8, 400 MW H6, and 400 MW H10, all in the Jiangsu Rudong project. The station will then convert the electricity into DC power, transmitting it via a submarine cable to land over a distance of 100 km, the longest cable distance in China.

 

The project is expected to be commissioned in later half of 2021 and once operational, it will be able to provide around 1.36 million households with their annual electricity needs.
