<p>Provided are a fuel supply device and a gas turbine electricity generation plant with which responsiveness to variations in the gas turbine load can be improved, and which can be manufactured easily, thereby reducing the manufacturing cost. The fuel supply device is provided with: multiple flow volume adjustment valves (13P, 13M, 13T) that adjust the flow volume of fuel flowing in a fuel supply system; a calculation unit (21) that calculates a required flow volume coefficient for the flow volume adjustment valve (13P, 13M, 13T) corresponding to one fuel supply nozzle, of different types of fuel nozzles, on the basis of at least the fuel pressure upstream from the flow volume adjustment valves (13P, 13M, 13T) with respect to the flow of fuel, a predetermined pressure, as the fuel pressure downstream from the flow volume adjustment valves (13P, 13M, 13T), and the flow volume of the fuel supplied to the one fuel nozzle; and a valve control unit (23) that controls the degree of valve opening of the flow volume adjustment valve (13P, 13M, 13T) corresponding to the one fuel nozzle on the basis of the required flow volume coefficient.</p> |
