Disclosed is a gas turbine power generating system capable of achieving a high output power and a high power generating efficiency under conditions with a small amount of supplied water and less change in design of a gas turbine. A fine water droplet spraying apparatus ( 11 ) is disposed in a suction air chamber ( 22 ) on the upstream side of an air compressor ( 2 ), and a moisture adding apparatus ( 7 ) for adding moisture to high pressure air supplied from the compressor ( 2 ) is disposed. A regenerator ( 5 ) for heating the air to which moisture has been added by using gas turbine exhaust gas as a heat source is also provided. With this configuration, there can be obtain an effect of reducing a power for the compressor ( 2 ) and an effect of increasing the output power due to addition of moisture to air ( 20 ) for combustion. Further, since the used amount of fuel is reduced by adopting a regenerating cycle, the power generating efficiency is improved.
