System and method for pumped storage by quitting underground coal mine engineering and underground space
The invention discloses a system and a method for pumped storage by utilizing quit underground coal mine engineering and underground space. The system comprises an upper reservoir, a lower reservoir, a pumping plant chamber, a power plant chamber, a diversion tunnel, a tail water tunnel, a surge chamber, a trash rack, a ventilation and transportation system and a ground ditch, the upper reservoir is a coal mine ground subsidence area or a ground water system, and the lower reservoir is an underground roadway, a chamber and a goaf of a quitted underground coal mine. According to the characteristics of underground coal mine engineering, the defect that the water pumping working condition and the power generation working condition of a water pump turbine of a reversible pumped storage power station are inconsistent is overcome, the pumped storage power station is fully constructed in underground engineering and underground space, a new energy power system can be matched, and multiple services such as peak shaving and valley filling, frequency modulation, phase modulation and emergency accident standby are provided for a power grid. The development of new energy is promoted, and meanwhile, a new development direction is provided for underground space utilization quitting from the mine and comprehensive treatment of mine water.
本申请公开了一种利用退出井工煤矿工程和地下空间进行抽水蓄能的系统及方法，包括上水库、下水库、抽水厂房硐室、发电厂房硐室、引水隧洞、尾水隧洞、调压室、拦污栅、通风和输运系统和地面沟渠；所述上水库为煤矿地面塌陷区或地面水系，所述下水库为退出的井工煤矿地下巷道、硐室和采空区。根据井工煤矿工程特点，克服可逆式抽水蓄能电站水泵水轮机抽水工况和发电工况不一致的弊端，充分地下工程及地下空间建设抽水蓄能电站，可配套新能源电力系统，为电网提供调峰填谷及调频、调相、紧急事故备用等多重服务，促进新能源的发展，同时为退出矿井的地下空间利用、矿井水的综合治理提供一条新的发展方向。
