The control device of a gas turbine power plant

The present invention relates to a control apparatus of a gas turbine power plant comprising a compressor (1), which is pressurized with air for combustion; intake spray device (3), to which air is sucked into the compressor (1) spray atomization flow rate through the flow regulating valve (13) to provide a water spray of liquid droplets; a combustor (2), which is mixed in the combustion / combustion air and fuel to produce high temperature combustion gas, the combustion switching operation ; turbine (4), with the combustion gases which drive the compressor (1) and a generator; spray flow rate adjusting valve (13), which controls the flow of water spray; compressor inlet inner wing (11), which controls the flow rate of air sucked into the compressor (1), the control device of the gas turbine power plant further includes a control unit (24), which generates fuel for the combustor of the combustion switching (2) air-fuel ratio to compensate for decreased air ratio calculating correction command signal to control the compressor inlet inner wing (11) based on the opening degree of the fuel-air ratio correction command signal or / And a spray flow rate adjusting valve opening degree (13) of said.
