A steam-injection type gas turbine system provided with a waste-heat boiler uses surplus steam effectively for cooling the stationary blades of a turbine. The steam-injection type gas turbine system includes an air compressor ( ) for compressing air, a combustor ( ) for mixing a fuel with compressed air to burn the fuel, a turbine ( ) driven by the energy of a combustion gas produced by the combustor ( ), a waste-heat boiler ( ) using an exhaust gas (G) discharged from the turbine ( ) as a heat source, a steam supply system ( ) for distributing steam generated by the waste-heat boiler ( ) to the combustor ( ), the stationary blades ( B) of the turbine ( ) and external steam loads ( ), and a steam distribution adjusting means ( ) for preferentially supplying steam to the external steam loads ( ), adjusting the rate of supply of steam to the combustor ( ) and supplying the rest of the steam to the stationary blades ( B).
