水面漂浮式光伏电站浮式基础动态稳定性分析
|
摘要
传统地面光伏电站开发受土地资源稀缺限制,极大阻碍了光伏发电技术的发展,如何有效解决光伏发电领域土地资源短缺的限制,成为光伏行业亟需解决的问题。水面漂浮式光伏电站可布置于江河海域的水面,摆脱了传统光伏发电受制于土地资源的影响,日益成为竞相投资的领域。活式基础作为水面漂浮式光伏电站中最为重要的部分,如何保证浮式基础在不同风浪载荷下的动态稳定性显得尤为关键。采用有限元分析软件分析了在不同风浪载荷下浮式基础的动态稳定性。分析结论与实际运行情况表明,漂浮式基础在波浪荷载作用下4个角属于荷载集中区,在设计中应予以加强。相关分析成果已成功应用于某实际项目中,验证了分析方法的可行性。
The development of traditional PV plant is nowadays strongly limited by the scarcity of land resource,which greatly hinders the development of photovoltaic technology,how to solve the land resources shortage problem becomes urgent in PV industry. The floating PV power station can solve the problems of land resources shortage produced by traditional PV power station and becomes a competitive investments area. How to ensure the dynamic stability of the floating foundation,the most important part of the floating PV power station,under various wind-wave conditions is a concern. We use the finite element to study the floating foundation dynamic stability under different waves. The results show that the four corner areas of the floating foundation are load concentrated and should be payed attention to in design and operation,and this phenomenon is also verified by practical project,which proves the feasibility of the method.
