Abstract

Accurate prediction of the transition process of a pumped storage power station is an important issue in the design and operation of the power station.In this paper, based on the in-situ test of the super-high-head pumped storage power station, the numerical model of the hydraulic transition process of the water transmission and power generation system is first established, Then carried out the comparison calculation of the real machine load rejection test to verify the reliability of the numerical calculation and obtain the pressure pulsation and calculation error, Finally, the prediction and analysis of extreme control conditions are carried out, and the pressure pulsation and calculation error correction are carried out. The research results show that the prediction results of the control parameters under extreme conditions are all within the design standards, which guarantees the safety of the power station's operation. This analysis method can provide reference value in similar pumped storage power stations.
