The world's largest wind turbine, with a rotor diameter of 230 meters, has been successfully installed! - The power distribution system and foghorn system are manufactured by Haien in Dalian!
On September 8th, the new generation of semi-direct drive unit EW8.5-230 from GE Wind Energy's Poseidon platform was successfully installed at the Shandong Energy Group Bozhong Offshore Wind Power B site project. With a rotor diameter of 230 meters, this unit boasts the largest rotor diameter among all installed units globally. GE Wind Energy achieves another breakthrough, leading China's wind power industry into the 230-meter rotor era!。
The power distribution and foghorn systems are designed and manufactured by Dalian Haien Gebhard Electrical Apparatus Co., Ltd., providing comprehensive protection for the platform's operation and safety. The development history of GE Wind Energy's offshore wind power projects essentially mirrors the history of China's offshore wind power industry. Based on years of accumulated leading experience in offshore wind power and the penetration of years of accumulated technology in complete units and core components, the unit aims for "high yield" and focuses on "high reliability," achieving "technological leadership."
- Improved transmission efficiency, enhancing power generation revenue;
- No high-speed coupling, fewer key components;
- No carbon brushes or lubricating grease, enabling maintenance-free generator operation;
- Gearbox and generator are air-replaceable, reducing lifecycle maintenance costs;
- New carbon fiber blades with dynamic rain erosion leading-edge protection to extend blade life.
In addition to core component technology penetration, GE Wind Energy's years of accumulated understanding and penetration of complete unit technology, from the perspective of systematic optimization design, further ensures "high reliability" and "high yield":
- Equipped with internationally advanced lightning protection technology to ensure the reliability of the entire unit's operation;
- Main bearing assembly uses intelligent "black technology" Sensor Roller technology for real-time monitoring of the main bearing operating status;
- Full lifecycle digital design, production, and maintenance management, combined with GE Wind Energy's LeapX control system, reduces the overall operating load;
- Full-perception digital interconnection, intelligently interconnected with GE Wind Energy's "Wind Cloud" platform, continuously improving unit utilization rate and wind farm yield.
GE Wind Energy ushered in a new chapter for mass installation of Chinese offshore wind power projects with its 3.6MW offshore units. It led China's offshore wind power industry into the deep sea with the nation's first "double ten" offshore wind power project, achieving breakthroughs with China's first far-sea intertidal wind power project, China's first "National Excellent Engineering Gold Award" offshore wind power project, and China's first 7MW-scale offshore wind farm. Now, the installation of the 230-meter rotor wind turbine once again leads the industry to a new height.
Moving forward, and not stopping there. In the future, GE Wind Energy will continue to adhere to the principle of "solution leadership based on technological leadership," constantly surpassing itself, collaborating with the industry chain, and jointly promoting industry development, advancing the clean energy transition, and promoting the prosperity and development of the new energy ecosystem. Dalian Haien Gebhard Electrical Apparatus Co., Ltd., will continue to uphold the concept of quality first and advanced technology to contribute to China's wind power industry.。
