Zusammenfassung:To provide a power generation system that can increase power generator output, and a control method therefor, as well as a program.SOLUTION: A power generation system comprises a boiler, a steam turbine to be rotated by using steam generated by the boiler, a power generator for generating power by the rotation of the steam turbine, and a system control device 15 for controlling the boiler. The system control device 15 comprises a correction value setting unit 20 for calculating a correction value on the basis of a deviation ΔMW between power generator requirement output MWD and power generator output when a load condition is a threshold value or more and a load change width is within a predetermined range, and a boiler control unit 40 for increasing the power generator requirement output MWD on the basis of the correction value, and generating a boiler input instruction BID that is an instruction for controlling the boiler.SELECTED DRAWING: Figure 3 【課題】発電機出力を増加させることのできる発電システム、及びその制御方法並びにプログラムを提供することを目的とする。【解決手段】発電システムは、ボイラと、ボイラで発生した蒸気を用いて回転する蒸気タービンと、蒸気タービンの回転により発電する発電機と、ボイラを制御するシステム制御装置15と、を備え、システム制御装置15は、負荷状態が閾値以上であり、かつ、負荷変化幅が所定範囲以内である場合に、発電機要求出力MWDと発電機出力との偏差ΔMWに基づいて補正値を算出する補正値設定部20と、補正値に基づいて発電機要求出力MWDを増加させ、ボイラを制御するための指令であるボイラ入力指令BIDを生成するボイラ制御部40とを備える。【選択図】図3
