摘要： PROBLEM TO BE SOLVED: To provide an elevator control system capable of detecting malfunction of a speed monitoring control device in a relatively simple structure.
SOLUTION: A speed monitoring control device outputs a speed information signal respectively when a speed of an elevator calculated based on an output signal of a first speed detector achieves a first speed which is equal to or slower than a rated speed and a second speed equal to or slower than the rated speed and faster than the first speed. The elevator control device detects abnormality of the first speed detector based on these speed information signals and a speed of the elevator that the elevator control device calculates based on the output signal of the second speed detector.

摘要： PURPOSE:To control the fluctuation in the drain water level of a moisture separator at the time of changing reactor output so that the generation of an unnecessary alarm can be controlled by controlling the opening degree of an intermediate valve in accordance with a regulating valve opening degree request signal. CONSTITUTION:A turbine output control system 14 is inputted with a turbine inlet pressure signal S1 by a pressure detector 13 and a turbine speed signal S2 and outputs the regulating valve opening degree request signal S3, a bypass valve opening degree request signal S4 and a load follow-up error signal S5. The fluctuation in the reactor pressure is thereby suppressed and the overspeed of the turbine speed is prevented. The load follow-up error signal S5 is made into a recirculation pump rotating speed request signal S6 by a recirculation flow rate control system 15. A change in the rotating speed of the recirculation pump 12 is made into a change in the coolant flow rate of the reactor 1 and as a result, the reactor output is changed. The regulating valve opening degree request signal S3 is inputted to an intermediate valve controller 16 and is made into an intermediate valve opening degree request signal S7 after the prescribed computation, by which the opening degree of the intermediate valve 5 is given. The fluctuation in the drain water level of a moisture separator is thereby suppressed.

摘要： PURPOSE:To realize a smooth load following operation of a nuclear reactor, by controlling a intermediate check valve by a load demand signal, making an output of a turbine generator follow the load demand and controlling an extraction valve so as to suppress a pressure deviation in a moisture separator. CONSTITUTION:A signal 78 is a controlling error signal to equalize a pressure PMS to an approximately constant signal 77. The signal 78 is fed to a regulator 28 having functions of proportioning and integration, and therewith an extraction value (EV) 27 is operated accordingly. Moreover, a mode in which a reverse demand against a function demand of an IV valve is fed to an accumulator element 42 as a forwarding control demand signal 76 in a block 52, is obtained by making the mode effective by operation of a switch 47. In this condition, a signal 72 is zero, and as the pressure PMS is approximately constant, a control valve (CV) 24 is not activated and an output sharing rate of a high pressure turbine is also constant, therefore, a pressure Pr does not change. As a result, because a reactor dome pressure Po to which a neutron flux responds most sensitively stays being unchanged, the most preferable operating condition can be attained.

摘要： PURPOSE:To set the gain of a feed water control system always at an optimum value by providing plural water level converters which are varied in conversion rates such as conversion constants and switching one convert to the other by a rapid change detection signal at the time of the rapid change of the load of an atomic power plant. CONSTITUTION:A steam regulating valve 101 is rapidly closed when a load interruption is generated. A turbine bypass valve 102 opens nearly simultaneously and the steam from a nuclear reactor 1 is introduced directly into a condenser 4. A selective control rod which is a part of a control rod 104 is inserted into the reactor 1, by which the reactor output is gradually decreased. The water level converter 30 is switched to the water level converter 40 by a switch 41 which receives the load interruption detection signal simultaneously with generation of the load interruption and the gain K2 to be optimized at the time of the load interruption is used in order to stably control the water level at this time. The gain K2 is set at the conversion constant larger than the conversion constant of the gain K1 to convert the mismatch quantity 32 between the feed water flow rate and the main steam flow rate as the larger value to the quantity corresponding to the water level and, therefore, a feed water control valve 9 is promptly throttled after the recovery of the water level and the overshooting of the water level is kept low.
