<p>A controller is intended for use in a gas turbine power plant that includes: a compressor 1 that compresses combustion air; a water atomization cooling apparatus 3 that sprays water drops of atomized water supplied via a water atomization flow rate regulating valve 13 over a flow of air drawn in the compressor 1; a combustor 2 that mixes the compressed combustion air with fuel to thereby burn a fuel-air mixture and generate combustion gas at high temperature and performs combustion switching during operation; a turbine 4 that uses the combustion gas to drive the compressor 1 and a generator; the water atomization flow rate regulating valve 13 that controls a flow rate of the atomized water; and a compressor inlet inner blade 11 that controls a flow rate of air drawn in the compressor 1. The controller includes control means 24 that calculates a fuel-air ratio correction command signal for compensating for reduction in a fuel-air ratio in the combustor 2 occurring during the combustion switching and, based on the fuel-air ratio correction command signal, controls an opening amount of the compressor inlet inner blade 11 or/and an opening amount of the water atomization flow rate regulating valve 13.</p> |
