The present electric power generation control device includes: an event detection unit which detects an event attributable to a deterioration in the balance between a torque input to a generator and an effective power output by the generator, the deterioration being caused by a reduction in a set value of the effective power received from the generator by an electric power converter when the electric power converter has detected a failure necessitating interruption of electric power transmission from the generator by a direct-current (DC) power transmission unit, the DC power transmission unit transmitting DC power, the electric power converter connecting a generator to the DC power transmission unit; and a torque command reduction unit which causes a reduction in a torque command to a motor when the event detection unit has detected the event attributable to the deterioration in the balance, the motor outputting the torque input to the generator.
