子力タービンの制御装置。 A main steam stop valve between the reactor and high pressure turbine,
A main steam pipe equipped with a steam control valve, etc. is inserted, and a reheat steam pipe is branched from the main steam pipe and connected to a moisture separator reheater. In a reheating nuclear power turbine, where it is reheated with steam from a reheating steam pipe,
A regulating valve is provided in the reheat steam pipe, and a valve opening correction signal generator generates a valve opening/closing control signal for the regulating valve using the deviation between the actual load signal and the load setting signal, and this valve opening correction signal A low value priority circuit selects either the low value signal from the speed control signal and the addition signal that adds the valve opening/closing control signal generated from the generator to the pressure control signal and gives it as the opening/closing control signal of the steam control valve. A control device for a reheat nuclear power turbine, comprising:
