中国完成世界首台兆瓦级商用浮空风电系统戈壁工况试飞

Core Insights - The successful test flight of the S1500 floating wind power generation system marks a significant milestone for China's renewable energy sector, being the world's first megawatt-level commercial airborne wind power system [1][3]. Group 1: System Specifications - The S1500 system measures 60 meters in length, 40 meters in width, and 40 meters in height, resembling a dirigible, with a designed power output of 1 megawatt (MW), making it the largest floating wind power device globally [3]. - It features a main gas bag and annular wings that form a giant duct, equipped with 12 sets of 100-kilowatt generator units, harnessing stable high-altitude winds to generate electricity [3]. Group 2: Advantages Over Traditional Systems - Compared to traditional land-based wind turbines, the floating wind power system eliminates the need for large tower structures, simplifying the foundation and reducing material costs by 40% and lowering the cost per kilowatt-hour by 30% [3]. - The system is designed for rapid relocation, making it suitable for various environments such as deserts, islands, and mining areas [3]. Group 3: Development and Future Plans - The research team, in collaboration with institutions like Tsinghua University and the Chinese Academy of Sciences, has overcome challenges related to the stability of the floating device, lightweight motors, and high-voltage transmission over kilometers [3]. - Future plans include conducting further environmental and scenario validations across multiple locations in China, with a goal to achieve mass production and deliver the first batch of grid-connected units by 2026 [5].
