Key Technologies and Research in the Construction of Pumped Storage Power Stations at the Yalong River Integrated Demonstration Base
The development process of pumped storage power plants has been accelerated by the"dual carbon"strategic development goal.This paper presents an overview of the pumped storage power station in Yalong River Basin,along with research and application of key technologies such as high rock sill removal,wide-amplitude pump turbine,pumping reliability of lower reservoir,integrated operation and scheduling of water-wind-light-storage multi-energy complementarity,insulation corona of electrical equipment under high cold and high altitude,seepage prevention of reservoir,TBM in high cold and high altitude areas and electric construction equipment.This paper offers insights into addressing key technical challenges faced by pumped storage power stations in high cold and high altitude areas.
