A method for operating a gas-supply system, particularly for a gas turbine, having a gas-carrying pipeline, a controllable compressor arranged in the pipeline and at least one consumer connected to the pipeline and located downstream from the compressor. The compressor is regulated as a function of a comparison between the setpoint discharge pressure of the compressor and the actual discharge pressure of the compressor. The energy consumption of the compressor can be reduced in that the setpoint discharge pressure of the compressor is determined as a function of a setpoint admission pressure of the consumer.

Gas supply arrangement and associated method, particularly for a gas turbine

A method of operating a thermal power plant, such as a gas turbine power plant, in which a rotary unit, such as at least one gas turbine stage, is driven by burning gaseous fuel inside a combustion chamber, with hot gases being formed, the rotary energy of which rotary unit is converted into another form of energy, such as into electrical energy. A load set point (L) of the thermal power plant is set by regulating the quantity of gaseous fuel fed to the combustion process. The thermal power plant is operated at a load set point (L), provided the gaseous fuel is fed to the combustion process through a gas line at a gas pressure p, with(),where p(L) represents a pressure value which depends at least on the load set point (L) of the thermal power plant.
