A control devicefor a power generation systemincludes a target voltage regulator partconfigured to adjust the target voltage Vr of a generator. The target voltage regulator parthas: a voltage decrease function to reduce the target voltage Vr of the generatorin accordance with a decrease amount of a detection value Sm of a rotation speed S of a gas engineor a frequency of the generatorif the detection value falls below an allowable variation value when a load is connected to the generatorvia a circuit breaker; and a voltage decrease limiting function to maintain the target voltage Vr of the generatorat an allowable lower limit voltage determined on the basis of an output voltage V which is allowable to carry out normal operation of the load if the target voltage Vr of the generatoris lower than the allowable lower limit voltage.
