Method for injecting water into a multistage axial compressor of a gas turbine

Method for injecting water into a multistage axial compressor (10) of a gas turbine to increase the power output, even under changing boundary conditions, wherein water is being injected at a plurality of points (18a - d) along the axial compressor; the injected water mass flow is controlled at the individual injection points in accordance with ambient conditions and operating parameters of the gas turbine in such a way that an evened-out loading in the individual stages of the axial compressor (10) is created.
