SEMI-UNDERGROUND PUMPED-STORAGE HYDROELECTRIC POWER STATION EMPLOYING OPEN-PIT MINE, AND METHOD FOR CONSTRUCTING SAME

摘要

A semi-underground pumped-storage hydroelectric power station employing an open-pit mine, and a method for constructing the same. The power station comprises a high-level water storage region and a low-level water storage region (20), a water delivery channel (15), and a bidirectional generator. The water delivery channel (15) communicates with the high-level water storage region and the low-level water storage region (20) and is disposed therebetween. The bidirectional generator is disposed between the high-level water storage region and the low-level water storage region (20), and is configured to generate pumped-storage hydroelectric power or electricity using water from the water delivery channel (15). The present method for constructing a semi-underground pumped-storage hydroelectric power station utilizes both the aboveground space and underground space of an abandoned mine, such that an open pit of the abandoned mine serves as a high-level water storage region, and tunnels of the abandoned mine serve as an underground water storage region.
