Abstract
In a method for cooling a turbine ( ), the supply of the cooling medium is regulated in accordance with the third power of the rotor rotational speed. The method is particularly employed in the period while the rotors run down after the termination of the on-load operation of the turbine ( ). The method ensures that cooling takes place according to requirement and a critical phase with respect to vibrations of the long blades can not, as far as possible, be reached.
