China's first national offshore wind power research and testing base transmission chain platform in east China's Fujian province began operation on December 26, 2024.

This is the country's first wind turbine ground test platform with independent intellectual property with the most comprehensive testing capabilities in China. It can simulate tests for 25 MW wind turbines under all operational conditions. In the future, it would be able to conduct ground testing and detection of large-capacity offshore wind turbines over 10 MW, regardless of the weather.

China has led the world in cumulative installed capacity of offshore wind power for three consecutive years, entering the era of large-capacity turbines. The growth necessitated a dedicated test site capable of supporting type certification for these advanced turbines.

Jointly invested by the State Grid, China Huadian Corporation Ltd., and other institutions, the offshore wind power base is the only testing center authorized by the National Energy Administration to conduct both type and grid connection certifications. The base includes a land test center and a test wind farm. The land center features a transmission chain platform and a 150-meter blade test platform.

The transmission chain platform integrates full-scale, high-fidelity simulations with unique adjustment functions not found in other domestic test facilities. It also includes the world's largest power grid simulation device, according to Fang Risheng, director of Science and Technology Department of the State Grid Fujian Electric Power Co. Ltd.

The under-construction blade test platform will introduce an ultra-long blade biaxial high-frequency loading test, crucial for advancing offshore wind power technologies, according to Chen Dawei from the Electric Power Research Institute of State Grid Fujian Electric Power Co. Ltd.
