In the field of hydropower station transient process simulation (HSTPS), characteristic graph-based iterative hydroturbine model (CGIHM) has been widely used when large disturbance hydroturbine modeling is involved.
However, by this model, iteration should be used to calculate speed and pressure, and slow convergence or no convergence problems may be encountered for some reasons like special characteristic graph profile, inappropriate iterative algorithm, or inappropriate interpolation algorithm, and so forth.
Also, other conventional large disturbance hydroturbine models are of some disadvantages and difficult to be used widely in HSTPS.
Therefore, to obtain an accurate simulation result, a simple method for hydroturbine modeling is proposed.
By this method, both the initial operating point and the transfer coefficients of linear hydroturbine model keep changing during simulation.
Hence, it can reflect the nonlinearity of the hydroturbine and be used for Francis turbine simulation under large disturbance condition.
To validate the proposed method, both large disturbance and small disturbance simulations of a single hydrounit supplying a resistive, isolated load were conducted.
It was shown that the simulation result is consistent with that of field test.
Consequently, the proposed method is an attractive option for HSTPS involving Francis turbine modeling under large disturbance condition.
