ABSTRACT:
A method and apparatus for regulating a steam turbine comprising at least one resuperheater arranged between a high pressure section and a low pressure section and in which a reference-actual value comparison of the rotational speed is performed to produce an adjustment signal derived from the reference value actual-value difference which is delivered from the difference between the impeller casing pressure of the high pressure section and the output pressure of the resuperheater which feedback signal is coupled into the regulation circuit opposite to the adjustment signal.
