Abstract: In der Regelanordnung für eine Dampfturbine (12), die mit einem Dampfbypasssystem betrieben wird, erfolgt eine Bypassventilsteuerung gemäß Sollwerten, die als Funktion eines Gesamtströmungsbezugs- oder CFR-Signals erzeugt werden. Das CFR-Signal stellt die Kesselauslaßströmung in sämtlichen Turbinenbetriebsphasen dar und wird erzeugt, indem die Summe des Dampfeinlaßsteuerventilströmungsbedarfs und des Hochdruckbypassströmungsbedarfs mit dem Kesseldruck (P ↓B) multipliziert wird. Ein Istlastbedarfs- oder ALD-Signal, das den Turbinendampfbedarf angibt, wird aus dem Produkt des Dampfeinlaßsteuerventilströmungsbedarfs und des Kesseldrucks erzeugt und zur Sperrventilsteuerung benutzt. Eine übermäßige Dampfströmung in dem Niederdruckbypassuntersystem (46, 48, 50) wird verhindert, indem die normale Regelung übersteuert wird, um einen starken Erhitzungsstoß in dem Kondensator (44) und den letzten Stufen des Turbinenhochdruckabschnitts (14) zu verhindern.
