Abstract

Die Erfindung bezieht sich auf ein Verfahren (und eine Einrichtung) zur Regelung einer Dampfturbine (1) eines eine Dampfturbine und einen Dampferzeuger aufweisenden Kraftwerkblocks, wobei das Ausgangssignal des Turbinen­ reglers (6) auf die Stelleinrichtung (9) der Turbineneinlaßventil­ anordnung (2) wirkt. Um bei einem solchen Verfahren den Turbinen­ regler (6) von solchen Stellgrößenänderungen zu entlasten, welche bereits aus der Änderung der Führungsgröße ersicht­ lich sind, wird dem Ausgangssignal des Turbinenreglers (6) ein Signal aufaddiert, das aus dem Leistungssollwert des Turbinenreglers (6) gemäß der für die Dampfturbine (1) gültigen Beziehung errechnet wird und in der errechneten Größe oder mit einem von 1 abweichenden Faktor k bewertet zur Summierstelle geleitet wird. The invention relates to a method (and a device) for controlling a steam turbine (1) of a power plant block having a steam turbine and a steam generator, the output signal of the turbine controller (6) acting on the actuating device (9) of the turbine inlet valve arrangement (2) . In order to relieve the turbine controller (6) of such manipulated variable changes in such a method, which are already evident from the change in the command variable, a signal is added to the output signal of the turbine controller (6) which corresponds to the power setpoint of the turbine controller (6) the relationship valid for the steam turbine (1) is calculated and sent to the summing point in the calculated size or with a factor k deviating from 1.
