ABSTRACT:
A cooled gas turbine power plant has a compressor and a high pressure turbine connected to the compressor. The cooling air quantity for the turbine is controlled in response to instantaneous load conditions and in direct response to the cooling air quantity control of the compressor. This control of the cooling air quantity for the turbine is achieved by a direct mechanical coupling of a slide valve for the turbine cooling air control with the control of the compressor, whereby good power output values and low fuel consumption values are achieved for the high pressure turbine, especially under partial load operating conditions. The compressor may be controlled by an adjustment of the angular position of its guide vanes or blades or by an adjustment of the quantity of its discharge air.
