Abstract EN
Accurate modeling of Kaplan turbine regulating system is of great significance for grid security and stability analysis.
In this paper, Kaplan turbine regulating system model is divided into the governor system model, the blade control system model, and the turbine and water diversion system model.
The Kaplan turbine has its particularity, and the on-cam relationship between the wicket gate opening and the runner blade angle under a certain water head on the whole range was obtained by high-order curve fitting method.
Progressively the linearized Kaplan turbine model, improved ideal Kaplan turbine model, and nonlinear Kaplan turbine model were developed.
The nonlinear Kaplan turbine model considered the correction function of the blade angle on the turbine power, thereby improving the model simulation accuracy.
The model parameters were calculated or obtained by the improved particle swarm optimization (IPSO) algorithm.
For the blade control system model, the default blade servomotor time constant given by value of one simplified the modeling and experimental work.
Further studies combined with measured test data verified the established model accuracy and laid a foundation for further research into the influence of Kaplan turbine connecting to the grid.
