编辑 根据国家能源局《"十四五"可再生能源发展规划》，2025年新增装机中深远海项目占比需达30%，对应装机 规模超1200万千瓦。 01 从近岸到深蓝：中国风电的战略跃迁 中国海上风电开发正经历历史性转折。截至2025年5月，全国海上风电累计并网容量突破4127万千瓦，连续 四年居全球首位。但一个显著趋势是，传统近海项目已无法满足能源转型需求——辽宁省累计并网125万千 瓦，江苏省最远项目离岸85.5公里，标志着中国风电开发正式进入"深蓝时代"。 这一跃迁背后是技术范式的根本性转变。当水深超过50米，固定式基础成本呈指数级增长，漂浮式技术成为 唯一可行方案。中国工程院院士指出："漂浮式风电不是固定式的简单延伸，而是涉及材料科学、流体力 学、智能控制等领域的系统性创新。" 2025年7月10日，华能联合东方电气研制的全球单机功率最大的17兆瓦直驱型漂浮式海上风电机组在福建福 清下线，叶轮直径达262米。标志着中国正式领跑全球漂浮式风电技术赛道。 技术突破：在17级台风中站稳脚跟 抗台风设计的三重突破 编辑 中国科研团队在台风适应性领域取得里程碑式进展。三峡集团研发的"三立柱+中间立柱"半潜式平台，通过 动态压 ...
