全球单机功率最大直驱型漂浮式风机下线|真人做爰a片免费观看茄子视频
中新社北京7月10日电 (记者 王梦瑶)据中国华能消息，全球单机功率和风轮直径最大的直驱型漂浮式海上风电机组10日在福建省福清市顺利下线，单机功率17兆瓦，标志着中国在海上风电装备制造领域取得新的突破，为中国海上风电走向深远海提供了新的技术支撑。
本次下线的17兆瓦直驱型漂浮式海上风电机组由中国华能牵头，联合中国东方电气共同研制，风轮直径为262米，风轮扫风面积约53000平方米，轮毂中心高度约152米。相较于半直驱、双馈等技术路线的漂浮式海上风电机组，该直驱型机组发电倾角增大2°，生存倾角增大3°，机组运动适应性更强，可在浮体发生更大倾斜角度时仍能持续发电，从而确保机组时间可利用率达到99%以上，同时可应对超24米超高海浪，可抵御17级超强台风。
华能清洁能源技术研究院海上风电部主任刘鑫介绍说：“直驱型漂浮式风力发电机组对气隙稳定性、通风散热、振动噪声控制等方面要求更高，也是本次项目研发团队集中攻关、重点突破的核心技术难点。”
据了解，该机组首次采用国产化大直径主轴轴承，叶片、发电机、变流器、变压器等关键部件也全部实现国产化。机组单机年输出清洁电能可达6800万度，能满足约4万户家庭一年的用电需求，下一步将在广东阳江海域进行示范验证。(完)
