摘要	This paper mainly studies the numerical simulation of the force process of the runner blades in the transient process of the pump-turbine. In this paper, dynamic simulation technology is used to carry out three-dimensional numerical simulation of the transient process of pump-turbine, and the star-ccm+ simulation software is combined with the CATIA parameterized model to realize the automatic update of the impeller and the numerical simulation calculation of the model iteration. This paper selects 2.4 m head as the numerical simulation working point to establish the basic simulation calculation model, and uses the cooling pump of the basic model for numerical simulation. The results show that with the increase of charge and discharge, the relative efficiency of the turbine does not change much, and the pump efficiency first increases and then decreases. The pump shaft power and turbine power increase with the increase in flow rate. The peaking depth of the coupling system is 82.33%, which is 10.63% higher than that of the reference pump turbine unit. As the external relative load increases, the output power and total efficiency of the system first increase and then decrease. When the external relative load is 0.48, the output power and total efficiency of the system reach the peak value of 8996.36 kW and 24.63%.
