Three-stage reservoir pumped storage system utilizing underground mine hole space
A three-level reservoir pumped storage system utilizing underground mine cave space comprises a high-level reservoir, a middle-level reservoir and a low-level reservoir, the drainage side of the middle-level reservoir is connected with the high-level reservoir through a middle-high-level booster pump, and the drainage side of the low-level reservoir is connected with the high-level reservoir through a low-high-level booster pump. A low-position and middle-position booster water pump is arranged between the low-position reservoir and the middle-position reservoir; in addition, water in the high-level reservoir is discharged to the low-level reservoir after doing work through the low-back-pressure water-turbine generator set, and water in the high-level reservoir is discharged to the middle-level reservoir after doing work through the high-back-pressure water-turbine generator set. The high-position water storage space, the middle-position water storage space and the low-position water storage space are utilized, flexible conversion of gravitational potential energy and electric energy of water is achieved through transfer of water in the three water storage spaces, and the function of flexible adjustment and energy storage is achieved. The method is suitable for pumped storage of reservoirs with dams and is also suitable for water storage, pumped storage and energy storage spaces of underground mines and roadways.
一种利用地下矿洞空间的三级水库抽水蓄能系统，包括高位水库、中位水库和低位水库，其中，中位水库的排水侧通过中高位升压水泵连接高位水库，低位水库的排水侧通过低高位升压水泵连接高位水库，且在低位水库和中位水库之间设置低中位升压水泵；另外，高位水库中的水通过低背压水轮发电机组做功后排至低位水库，高位水库中的水通过高背压水轮发电机组做功后排至中位水库。本发明利用高中低位三个储水空间，通过水在三个储水空间的转移，实现水的重力势能和电能的灵活转换，达到灵活调节储能的功能。既适用于有坝水库的抽水蓄能，也适用于地下矿洞、巷道作为储水抽水蓄能空间的。
