Popis:	An optimized nonlinear robust strategy is proposed for coordinated excitation and governor of hydroturbine generator sets. Developed using the non-elastic water hammer model, the new controller is applied to the elastic one successfully. An integral estimator is used to observe and compensate for the entire unknown dynamics. The controller parameters are optimized via genetic algorithms. Simulation results show that the proposed nonlinear controller demonstrates not only better adaptability against changes of model and its parameters, but also excellent dynamic performance against three-phase short circuit fault and load disturbances. Therefore we conclude that the proposed controller offers a promising solution to the hydroturbine generator set control problems.
