Abstract
Provided is a gas turbine control device that is used in a generating facility including a gas turbine and a generator for generating power when at least rotational power of the gas turbine is transmitted, the gas turbine control device including a first control section for obtaining a first fuel control command for causing generator output to follow a generator output set value decided based on a demand load, where the first control section has a feedback control section (60), and the feedback control section (60) includes a subtraction section (62) for calculating a deviation of the generator output with respect to the generator output set value, a PI control section (64) provided in a later stage of control than the subtraction section (62), and a peak suppression section (66) for suppressing a peak in amplitude characteristics of the generator or a utility grid including the generator.
