In order to enhance the tracking performance of power generation equipment with respect to a load variation and increase the reliability of the power generation equipment, a dynamic characteristic model simulating the dynamic characteristics of a multi-shaft gas turbine is used to calculate an output prediction value of a first power generator in a case where a combustor is controlled so as to match the output of the first power generator to an output target value; on the basis of the output target value and the output prediction value of the first power generator, a first power generator output instruction value as an instruction value for the output from the first power generator to a power system and a second power generator output instruction value as an instruction value for the output from a second power generator to the power system are calculated; and the combustor is controlled on the basis of the first power generator output instruction value and a frequency convertor is controlled on the basis of the second power generator output instruction value.
