The control effect by using the conventional method is not satisfied because of the grey character caused from time-variant parameters of hydro-generator units and its governor. The grey extra-deleting control theory is applied to the governor design of hydro-generator units in this paper. After the mathematic model of hydro-generator and its governor are founded, the grey extra-deleting controller is designed and its effect is studied compared with the conventional proportional–integral–derivative governor. The simulation results indicate that the grey extra-deleting controller can improve dynamic characteristic of hydro-generator units.
