摘要： PURPOSE:To improve the stability of pressure control by correcting a control signal for an upstream valve controller to control pipe pressure between two valves to a fixed value by means of a signal corresponding to the square of a valve opening for the lift of a downstream valve. CONSTITUTION:A secondary pressure control valve 2 is provided on a high pressure steam line 1, and its downstream is provided with a turbine governor valve 4. Pressure in a secondary pressure line 3 between the above valves is controlled to a fixed value Ps by adjusting the said controller 2. A lift command signal for the governor valve 4 is inputted in a function generator 11, in which a signal corresponding to the square of opening for a valve lift is formed to maltiplicatively correct an input signal for a proportional-plus-integral controller 10 in a controller for the said valve 2. Consequently, the damping coefficient of a secondary pressure controller can be kept at an optimal fixed value to improve the stability of pressure control.

摘要： PURPOSE:To cope with any fault of a controller of a using system without giving any disturbance to a plant to be controlled, by providing a tracking device and a fault diagnosing device and controlling the output level when the outputs of both devices are switched. CONSTITUTION:If a fault of a controller 1A of a using system is due to a sudden change, the deviation between a control signal Qa of a using system and a control signal Qb of a waiting system and the variation of a process quantity P are immediately produced. Thus a fault diagnosing device 3 works in a short time to detect the fault of the controller 1A. Then the device 3 gives a switch signal S to a control system switch 2 to start a controller 1B of a waiting system. In case the controller 1A has a fault owing to a slow change of its control signal, a deciding circuit 4B applies a decision signal V to a tracking signal output circuit 4C. Then a tracking signal setting circuit 4A applies a tracking signal T to the controller 1B. The signal T is stored previously when the deviation between signals Qa and Qb is small and equal to the normal value of the controller 1A. While the device 3 gives a signal S to the switch 2 to start the controller 1B.

摘要： PURPOSE:To improve reliability and controllability by detecting the hunting of an air operation type adjusting valve due to the trouble of a booster relay and performing the switching to the valve controller in a waiting system. CONSTITUTION:Each of valve-lift signal 21 and opening-degree instruction signal 26 vibrates in a short cycle. Since a valve-lift standard signal hardly varies, a valve-lift deviation signal 23 and an opening-degree instruction deviation signal 27 vibrate. If the set value of a comparator 13 is set to a value smaller than the amplitude of the vibration, the vibration of the valve-lift deviation signal 23 due to the trouble of a booster relay exceeds the set value at each certain time intervals, and a count signal 24 is transmitted at each time. When the count signals 24 are transmitted several times in continuation, and said value exceeds the set count of a counting circuit 14, a valve controller switching signal 25 is transmitted.

摘要： PURPOSE:To enable positive control for the frequency fluctuation of the titled system while keeping the fluctuating width of an allowable load for the primary system by a method wherein a govenor regulating rate determining decide the govenor characteristics with respect to the fluctuation of revolution speed is made to be a polygonal line characteristics which becomes infinity in a range larger than designated deviation. CONSTITUTION:A govenor control system in an atomic energy power plant is composed of a turbine revolution speed detector 1, a subtracter 2, a govenor regulating rate 9, a subtractor 4, a govenor characteristics 5, a valve characteristics 6, a turbine output power characteristics 7 and a load controller 8. A turbine output power fluctuation is made to be limited within the fluctuation width of an allowable load for the primary system by controlling a govenor valve due to the deviation of a turbine revolution speed. In this case, the govenor regulating rate 9 determining the govenor characteristics 5 for the fluctuation of the revolution is made to be a polygonal line characteristics which becomes infinity in a range larger than the designated deviation. The govenor valve is controlled until the revolution deviation reaches within the designated value, for instance, less than 0.06Hz, then the controlling is stopped when the deviation exceeds the designated value and prevents the absolute value of load fluctuation from exceeding, for instance, 2.5%.
