Abstract

Die Erfindung betrifft eine Methode und eine Regeleinheit (CM) zum Anfahren einer Dampfturbine (ST) auf eine Synchrondrehzahl (nsync), welche Dampfturbine (ST) in einem Kraftwärmekopplungssystem (1) mit einem Kessel (B) und mindestens einer zwischen dem Kessel (B) und der Dampfturbine (ST) in einer Dampfleitung (FSL) angeordneten Ventil (CV) mit regelbarer Öffnungsstellung betrieben wird. Herkömmliche Anfahrprozeduren sehen vor, dass die Öffnungsstellung (X) des Ventils (CF) ausschließlich in Abhängigkeit von der Drehzahl (n) der Dampfturbine (ST) geregelt wird. Dies kann zu ungewollten Schnellschlussereignissen führen. Die Erfindung schafft Abhilfe, in dem während des Anfahrens die Öffnungsstellung des Stellventils (CV) vorübergehend in Abhängigkeit von dem Frischdampfdruck (PF) geregelt wird.
