World's Largest Offshore Wind Converter Station Heads for Installation Offshore China


ZPMC has shipped what it describes as the world's largest offshore converter station for installation offshore Guangdong Province, China.

Named Haifeng Heart, the 2 GW facility will support the Three Gorges Yangjiang Qingzhou V and Qingzhou VII offshore wind farms and is expected to deliver around 6 billion kWh of renewable electricity annually once operational.

According to ZPMC, the project sets several industry records, including the largest offshore converter station capacity, the highest-voltage offshore wind flexible DC transmission system at ±500 kV, and the first use of ±525 kV DC subsea cables in an offshore wind project.

The converter station measures 85.5 metres long, 82.5 metres wide and 44 metres high, with a total weight of approximately 25,000 tonnes.
Offshore converter stations enable efficient long-distance transmission of electricity generated by wind turbines by converting alternating current (AC) into direct current (DC), reducing losses and supporting the development of larger projects farther offshore.
