PROBLEM TO BE SOLVED: To enhance an energy efficiency in a fuel compressor system for a gas turbine. SOLUTION: An electric motor 21 driving a fuel compressor 11 is controlled in frequency by an inverter 22, and a command signal is output to the inverter 22 from a control device 23, thereby converts an inverter frequency into a variable frequency to be outputted to the electric motor 21 out of the inverter 22. Since the compression work of the fuel compressor can be adjusted according to a case by adjusting an inverter frequency in response to a case when an inverter frequency is to be set up, a fuel compressor system can thereby be transformed into one very high in efficiency from the stand point of energy.
