Assumption and Analysis of Standardization of Pumped-storage Power Stations Under Different Heads
To adapt the rapid development of pumped storage power stations and to solve the problems of equipment insufficient supply,this paper analyzes the difficulties of standardization of pumped storage equipment in China.Based on the statistical laws of operating parameters,the composition of traditional blades and splitter blades is proposed to achieve the standardization of runner size.According to basic hydraulic formulas,the mechanism of standardization of turbine ro-tational speed and diameter under different heads is discussed,and the advantages and disadvantages of standardization of runners are analyzed.On this basis,the overall framework for standardization of electromechanical equipment,under-ground plant,etc.in pumped storage power stations is proposed.The research is of great significance to the standardiza-tion work in China's pumped storage industry.
