Modeling of the Hydro-turbine Governor System of the Jinshuitan Hydropower Plant

The modeling method of the hydro-turbine governor system of the Jinshuitan hydro-turbine generator for electric power system analysis is presented.By use of the step response method,both linear model and nonlinear models of hydro-turbine governor system under different operating conditions are established.In order to verify the provided models,the response area error method is proposed.Furthermore,simulation results are compared with the demand of first time frequency modulation and it is proved that the provided models of hydro-turbine governor system satisfy the demand of practical projects.
