The device has a steam circuit with a control path for regulating control valve opening depending on measured turbine speed. It has further measurement sensors (15,17,19) for pressure and temperature in the steam circuit before and after the turbine and a measurement value transmission arrangement (16,18,20) for passing them to a regulator (11) for determining control values taking account the actual values and efficiency-optimized demand values. The device has a steam circuit with a heating boiler (1) for heating steam from a medium, a fresh steam line (2) for feeding steam to a control valve (3), an expansion turbine (4), a generator (5), a converter (6) for adapting the generator frequency to a defined mains frequency for a supply network, a steam pipe (2') for returning expanded steam to the boiler and a control path for regulating control valve opening depending on measured (12) turbine speed. AN Independent claim is also included for the following: (a) a method, especially for operating an inventive device for regulating a turbine for optimal efficiency.
