Calculation and Analysis of Large Fluctuation Transition Process of Pumped Storage Power Station in East China
In the operation of reversible pump turbine units,there are many operating conditions and frequent transitions,and the hydraulic transition process is more complex,requiring separate calculation and analysis.This paper focuses on the layout of the water delivery system of a pumped storage power station in East China,selects a reasonable guide vane closing law,draws on the four quadrant curve of similar units,and conducts numerical simulation and analysis of the large fluctuation transition process.The results show that under the selected guide vane closing law and four quadrant curve,the calculated control values for each operating condition meet the design requirements,which can provide certain reference for other similar projects.
