  • Procedure and device suitable for the speed control of a closed gas turbine plant containing a working medium cycle
    Patent number: 3932996
    Abstract: The closed gas turbine plant is fitted with at least one by-pass valve serving as an adjusting member for the working medium cycle, and uses measuring transformers for measuring the working medium cycle high and low pressures as well as the actual and nominal speeds of the turbine. A regulator has a first regulator part including an integrator, and the difference signal, between the speed nominal value and the speed actual value, is processed in this first regulator part. The regulator has a second regulator part in which signals representative of the working medium cycle high pressure and the working medium cycle low pressure are combined in an adding manner and the output signals of the two regulator parts are supplied to a third regulator part which controls the by-pass valve or valves.
