中国破世界纪录！全球最大开放式海上光伏投产，攻克3大技术难题

Core Viewpoint - The article discusses China's significant advancement in offshore photovoltaic (PV) technology, highlighting the construction of the world's largest open-sea PV power station, which has a capacity of over 1 million kilowatts, setting a new industrial standard for offshore PV projects [3][8][22]. Group 1: Project Overview - The offshore PV project is located 8 kilometers from the coast of Dongying, Shandong, and consists of 2,934 platforms, each larger than a standard football field [6][12]. - The platforms are securely anchored to the seabed using a self-developed steel truss platform foundation system, with thousands of specialized steel piles driven into the seabed [6][8]. Group 2: Engineering Challenges - The project overcomes significant engineering challenges, including the need for platforms that can withstand typhoons, ice, and corrosion while maximizing power generation efficiency [8][9]. - A unique 66 kV high-voltage submarine cable and land cable system is employed to transmit electricity back to shore, representing a rare "large capacity, low loss" solution in global offshore PV systems [9][11]. Group 3: Environmental Considerations - The project incorporates an innovative "fishing and solar integration" model, allowing for fish farming beneath the solar panels, which generates an annual revenue of 27 million yuan [12][14]. - The foundation piles also serve as artificial reefs, enhancing marine biodiversity and alleviating environmental concerns associated with the project [16]. Group 4: Economic Impact - The project has stimulated collaboration among over 25 enterprises, achieving an impressive installation efficiency of 9 platforms per day, indicating a shift towards industrialized production in PV engineering [17]. - It is characterized by self-investment, self-operation, and a domestically developed technology route, with 19 patents applied for, showcasing a transition from technology importation to knowledge exportation [19][20]. Group 5: Global Implications - Many countries have shown interest in offshore PV technology but have hesitated due to the complexity and high stakes involved in project execution [20][22]. - China's successful implementation of this project serves as a textbook example for the global community, establishing new standards and practices in the offshore PV industry [22].
