Abstract
PURPOSE: To prevent the piping of a boiler from pressure raising by rapid closing of a regulating valve, by connecting an intermediate portion between the boiler and the regulating valve, and a passage between a condenser and a turbine with each other by a by-pass adjustment valve.
CONSTITUTION: A regulating valve 3 is closed at a speed V1 by a runback instructing signal that is produced when some trouble is caused with the stator cooling system. At the same time, this instruction signal is transmitted to a pressure regulator 17 for controlling the opening of the turbine by-pass adjustment valve 15, so that differential pressure on the opposite sides of the regulating valve 3 becomes equal to a set value of pressure determining means 18. Although output current of the turbine 4 delays a short while corresponding to the inertia of the turbine 4, it follows up the closing motion of the regulating valve 3 the more promptly depending on the amount of by-passed steam, so that runback of load can be accomplished in reliable manner.
