Pump-turbine is the key equipment of UPSS. The characteristics of large drop, small space and poor water quality of UPSS requires the pump-turbine to be of ultra-high head, small volume and high corrosion resistance. Through the analysis of domestic and foreign research status, it is found that the research on pump-turbine in UPSS using abandoned mine is not comprehensive, the study on the corrosion mechanism of pumpturbine with mine water as working medium is not systematic, nor the transition process of pump-turbine frequently switching working conditions for new energy consumption is clear. Therefore, it is suggested to further develop a hydraulic model design optimization technology, research safe and stable operation technology in the transition process in frequent switching conditions, and study the coupling mechanism of corrosion-sediment wear-cavitation erosion and collaborative control technology., authors=ZHANG Baosheng¹, CHEN Ning¹, GAO Bo², CHEN Fan², authorsList=ZHANG Baosheng, CHEN Ning, GAO Bo, CHEN Fan, authorCompany=1.
