Beschreibung
Zusammenfassung:	The invention provides an underground well type combined energy storage system which comprises a pumped storage power station and a gravity energy storage power station, the pumped storage power station and the gravity energy storage power station share a vertical shaft, a ground transformer substation and a power line, the vertical shaft is used as a traffic hole and a ventilation hole, the length is shorter, the work amount is saved, gravity energy storage can be developed, and the space is efficiently utilized. And good economic benefits can be obtained. 本发明提供一种地下井式联合储能系统，包括抽水蓄能电站和重力储能电站，抽水蓄能电站和重力储能电站共用竖井、地面变电站和电力线，利用竖井作为交通洞和通风洞，长度更短，节省工程量，可开发重力储能，空间得以高效利用，能够取得较好的经济效益。
