ABSTRACT:
A method of, and apparatus for, regulating a resuperheated steam turbine wherein there is carried out a reference value-actual value comparison of the rotational speed and there is derived an adjustment or control magnitude from the reference value-actual value difference, this adjustment magnitude being infed to a regulation valve arrangement. There is derived from the resuperheated pressure a feedback magnitude which, as a function of time, yields to null and is coupled into a regulation circuit opposite to the adjustment magnitude.
