Combined water pumping energy storage system of underground space
The invention relates to the technical field of water pumping energy storage, in particular to an underground space combined water pumping energy storage system which comprises a first horizontal well and a second horizontal well which have height difference, a first gate is arranged at one closed end of the first horizontal well, the first horizontal well is located above the second horizontal well, and a second gate is arranged at the other closed end of the first horizontal well. A vertical hoistway is arranged between the first horizontal hoistway and the second horizontal hoistway, the top of the vertical hoistway is located between the first gate and the closed end of the first horizontal hoistway, the first horizontal hoistway located underground is used for storing water, too fast water loss caused by ground surface high temperature is avoided, water can be better saved, and meanwhile in the water pumping and energy storage process, the water pumping and energy storage efficiency is improved. Water flow can store energy at the first hydraulic turbine set and the second hydraulic turbine set, the energy storage capacity can be greatly improved, the inclined well, the first horizontal well, the vertical well and the second horizontal well are combined, the pumped energy storage water flow only circularly flows underground, and pollution from the ground is effectively avoided.
本发明涉及抽水储能技术领域，具体的是一种地下空间的联合抽水储能系统，本发明包括存在高度差的第一水平井道和第二水平井道，所述第一水平井道的一个封闭端设置有第一闸门，第一水平井道位于第二水平井道上方，第一水平井道和第二水平井道之间设置有竖向井道，竖向井道的顶部位于第一闸门和第一水平井道的封闭端之间，通过利用位于地下的第一水平井道进行储水，避免地表高温导致水量散失过快，可以更好的进行节水，同时抽水蓄能过程中，水流会在第一水轮机组和第二水轮机组两处进行储能，可以大幅提高储能量，将倾斜井道、第一水平井道、竖向井道和第二水平井道联合起来，使得抽水蓄能水流只在地下循环流动，有效的避免了来自地面的污染。
