A method is disclosed for cooling a gas turbine having a turbine, wherein a rotor, which rotates about a machine axis, carries a plurality of rotating blades, which are mounted by blade roots and extend with their airfoils into a hot gas path of the gas turbine. The rotor is concentrically surrounded by a turbine vane carrier carrying a plurality of stationary vanes, whereby the rotating blades and the stationary vanes are arranged in alternating rows in axial direction. An extended lifetime with external cooling is achieved by providing first and second cooling systems for the turbine.

The present disclosure relates to a system to compensate for mechanical forces on a rotating rotor of an electric machine, to a method for compensating mechanical forces on a rotating rotor of an electric machine, and to a use of a corresponding system. Disclosed is a system for compensating torsions at a rotating rotor. The system includes at least one measuring device for measuring specific properties of the rotor, an analyzer unit for analyzing the measurement data of the measuring device, a compensation means for compensating the torsions at the rotor, the compensation means comprise a power supply unit generating a signal adapted in amplitude and frequency to the measured properties of the rotor, and to apply the generated signal to the rotor, and the power supply unit is a frequency converter.
