Abstract
PURPOSE: To smoothly make possible the full admission/partial admission valve switching control with giving no damage to the turbine by a method wherein pressure detectors provided before and after a main steam stop valve are checked whether they operate normally or not before the full admission/partial admission valve switching control is performed.
CONSTITUTION: State signals a of various parts of the plant are inputted to an input unit 7 to calculate the difference of the pressures at before and after the main steam stop valve 3 at a pressure difference calculating unit 11. The abnormality of the pressure detectors 5 and 6 are detected at an abnormality detecting unit 12 and displayed at an abnormality display unit 13. If either of the pressure detectors 5 and 6 shows abnormality as a result of checking by the unit 12, the abnormality detecting unit 12 outputs a display command b to display the occurrence of the abnormality at the abnormality display unit 13 and the inhibit the following proceeding of the full admission/partial admission valve switching control (full admission-partial admission switching control in which the main steam stop valve 3 is fully open and at the same time a steam governing valve 2 is throttled when a bypass valve 4 is fully open).
