Problems solved by technology

However, in these tool software, the model of the hydro turbine regulation system provided by it is often simplified to make the model simpler, inconsistent with the reality, so that it cannot reflect the real behavior of the hydroelectric unit in the dynamic process of the power system

[0003] This is because due to the influence of professional division of labor and the lack of early research methods, it is believed that the hydraulic transition process, mechanical transition process and electromagnetic transition process of hydroelectric units are inconsistent in time scale, and can be studied separately; in addition, considering the dimension and speed of calculation , in the transient stability calculation of the power system, the hydraulic system generally adopts a simp
