Abstract

A hydroelectric power generation control system reduces, when load interruption is executed on a power generator, an opening degree of a guide vane by executing a first process of reducing the opening degree of a guide vane to less than that prior to the load interruption and a second process of reducing the opening degree of the guide vane to less than that at a time of completion of the first closing in such a manner that an amount of change in the opening degree of the guide vane per a predetermined time is less than that in the first process. A transition from the first process to the second process is made when the rotational speed of the water turbine is equal to or lower than the maximum rotational speed after a start of the load interruption and a water pressure change condition is satisfied in the first process. The water pressure change condition is that a change rate of the water pressure in at least one of the pipe and the casing becomes equal to or higher than a predetermined threshold within a time of 1 second or less.
