In this paper, a quasi-ternary calculation method for the flow field of a Francis turbine with high stability is introduced. The flow field inside the rotor is calculated iteratively by the integral equation method of S1 flow surface and the finite element method of S2 flow surface. At the same time, a runner developed by Harbin Institute of Electrical Engineering was used as an example to calculate and calculate and analyze the results
