Title:
CONTROL DEVICE FOR GENERATING PLANT
Document Type and Number:
Japanese Patent JPS63243411
Kind Code:
A
Abstract:
PURPOSE:To enhance the safety and reliability of a generating plant by setting back a plant output instruction signal automatically when it is detected that a demand instruction signal for a steam flow rate is below the plant output instruction signal. CONSTITUTION:The titled device comprises an output instruction device 17, a nuclear reactor output control device 18, primary and secondary cooling system flow rate control devices 19 and 20, a feed water flow rate control device 21 and a main steam pressure control device 22. And the titled device is so controlled as to make a plant output signal from an output instruction device 17 approximately proportional to a main cooling system flow rate within the range of the rated plant output, for example, within 40% to 100% of the output, and the output of a nuclear reactor is concurrently adjusted, thereby making turbine generator output follow up the nuclear reactor output. In this case, it is detected whether a flow demand instruction signal to a governing valve 11 drops below a plant output instruction signal, and the titled device is so constituted that the plant output instruction signal is automatically set back, when there is any drop detected.
