Coupling floating type photovoltaic closed pumped storage power generation system
The invention discloses a coupling floating type photovoltaic closed pumped storage power generation system, which implements a cascade layout measure of a multi-stage reservoir according to different geological conditions, and adopts a gradient water delivery and convergent water drainage mode to realize separation of a water delivery pipe and a water drainage pipe. The problem that a photovoltaic cooling water conveying path is inconsistent with a water discharging path due to the fact that the photovoltaic cooling water conveying path winds around a photovoltaic panel is solved, meanwhile, a fan-type floating structure is adopted in the photovoltaic system, the water surface cross section area changes along with the change of the water level, the floating structure of the floating photovoltaic system is automatically opened and closed, it is guaranteed that the covering rate on the water surface is not changed, and the evaporation rate of a water body is reduced. According to photovoltaic power generation load changes, the direct-current water pumping unit is adjusted, the water hammer phenomenon is avoided, and the safety and reliability in the water pumping and energy storage process are improved. According to the invention, the problems of water surface coverage rate and photovoltaic extrusion of floating photovoltaic in pumped storage are well solved, and meanwhile, the pumped storage unit can cope with the randomness, volatility and intermittent change of renewable energy systems such as light, wind and the like.
本发明公开了一种耦合漂浮式光伏的封闭式抽水蓄能发电系统，根据地质条件的不同，实施多级水库的梯级布局措施，并采用梯度输水，汇集下水的模式，实现输水管与下水管的分离，解决因光伏冷却输水路径绕经光伏板而导致与下水路径不一致问题，同时，光伏采用扇式漂浮结构，随水位的变化水面截面面积同时变化，漂浮式光伏的漂浮结构进行自动开合，保障对水面的遮盖率不变，降低水体的蒸发率。根据光伏的发电负荷变化，调节直流抽水机组，避免水锤现象，提高抽水蓄能过程中的安全性及可靠性。采用本发明在良好解决漂浮式光伏在抽水蓄能中水面覆盖率与光伏挤压问题的同时，实现了抽水蓄能机组可应对光风等可再生能源系统的随机性、波动性和间歇性变化。
