Claims

[Scope of utility model registration request]

In a control device for a feed water pump turbine, which drives the feed water pump turbine using extracted steam from a power generation turbine and high enthalpy main steam diverted from the upstream side of the power generation turbine, a flow rate transmitter that generates an output, a computing device that calculates the outputs of the flow transmitter and the water supply flow rate setting device and outputs the deviation thereof, and a water supply device that inputs the output of this computing device and outputs a water supply flow rate adjustment signal. A flow rate controller, a gain adjuster that controls the opening degree of the outlet valve based on the output of the controller, and a normal rotation speed setting device or an in-house rotation speed input via the output of the water supply flow rate controller and a switch. a high value selector that outputs one of the higher values among the outputs of the number setting device; a calculator that inputs the output of the high value selector and the output of the rotation speed detector of the water supply pump turbine and calculates a deviation therebetween; A water supply pump turbine control device comprising a low pressure regulating valve and a high pressure regulating valve whose opening degree is controlled by the output of this computing unit.
