摘要： PROBLEM TO BE SOLVED: To provide a distributed failure supervising system capable of properly supervising failure signals without being affected by hardware failure.
SOLUTION: Controllers 2a-2m connected to a network 1 and operating/supervising devices 3a-3m are provided with network normality signal output means 13a-13n, 14a-14m for outputting network normality checking signals to a network 1, and software diagnosing circuits 5a-5m, 6a-6m which perform self-diagnosis and output the results of the self-diagnosis to the network. The network normality checking signals are sent to a network diagnosing means 15 via the network 1 and the results of the self-diagnosis are sent to a supervising means 10. This allows failure signals to be properly inputted for the supervision of failure without being affected by hardware failure.

摘要： PROBLEM TO BE SOLVED: To prolong a life of a motor valve by optimally and automatically controlling the motor valve, and furthermore minimizing iterative operations of the valve to promptly change a process value to a target one.
SOLUTION: A control device 1 of the motor valve controls the motor valve so that the process value is adjusted to the target one by presetting output time and down time when the valve is instructed to be opened or closed, and by adjusting valve opening per inch. The control device fixes the down time of a valve opening instruction or a valve closing instruction and enables continuous change of the output time according to the deviation between the target value and process value by output from a motor valve output function circuit 20.

摘要： PURPOSE: To prevent a gas turbine load and a steam turbine load from overshooting, by selecting gas-turbine load control when a deviation signal between a setting signal and an actual signal at a shaft load is above a given level, and generating a deviation signal, as a load control signal, between a load setting signal and a load calculation signal for the gas turbine. CONSTITUTION: In a shaft load control unit 10, a deviation signal between an actual shaft-load signal and a shaft-load setting signal from a setting signal generating means 12 is generated as a load control signal by using a deviation calculation means 13a of a load control signal switching means 13. When the deviation signal between the actual signal and the shaft-load setting signal is above a given level, the load setting signal generating means 12 is selected for gas-turbine load control. After that, a deviation signal between a gas-turbine load setting signal and a gas-turbine load calculation signal is generated as a load control signal so that a gas-turbine load and a steam-turbine load are prevented from overshooting.

摘要： PURPOSE: To secure a safety operation of a gas turbine and prevent a plurality of burners from being damaged by computing an excess temperature and outputting an excess temperature detection signal in an excess temperature combustion state when the exhaust temperature of either one of burners exceeds a specified setting value. CONSTITUTION: When a temperature signal A at an exhaust gas temperature detection point is determined to have exceeded a setting signal B by a comparison means 10, an ON signal is inputted into an on-delay timer 12. The on-delay timer 12 outputs an ON signal when the ON signal is inputted and maintained for a specified time, This ON signal is inputted into an OR operation means 13 where the OR of all the portions of gas temperature detection points are computed. As a result of the computation, when excess temperature combustion is generated even at a drum of a burner 1, a partial value of the exhaust air temperature equivalent to the position of the burner which has generated the excess temperature combustion rises so that the ON signal is outputted from the comparison means 10, if the operation continues for a few seconds as set to the on-delay timer 12, an excess temperature detection signal of the burner is outputted and the supply of fuel is halted, thereby bringing a gas turbine to a safety stop.

摘要： PURPOSE:To enable stable combustion, even at the time of system frequency variation in the governor-free operation, by controlling a pilot distribution valve and a main distribution valve by a signal corresponding to a load request signal not including minute variation. CONSTITUTION:A gas turbine control device is provided with a first low-value priority device 25 in which a load-speed control signal (a) and an exhaust gas temperature restricting control signal (b) are input and either signal of the lower value is output to a fuel flow control valve 9. The device is also provided with a second low-value priority device 29 in which a speed setting signal (f) and the exhaust gas temperature restricting control signal (b) are input and either of the lower value is output as a control signal for controlling a pilot distribution valve 10 and a main distribution valve 11 in a prescribed distribution ratio. In this way, the speed setting signal (f) is output from the second low-value priority device 29 during the speed regulating operation for controlling the pilot and main distribution valves in a prescribed distribution ratio. Even if the fuel flow control valve 9 fluctuates slightly, there is no minute fluctuation in the control signal for controlling the pilot distribution valve 10 and the main distribution valve 11, so that there is few mutal interference with the fuel flow control valve 9 and stable combustion can be obtained.

摘要： PURPOSE:To prevent the long time fluctuation of the inlet guide vane of a compressor at an intermediate opening when a gas turbine generator output is increased in formed of a load increase and automatic load control operation attains its target operation before it attains a base operation point so as to reduce the burden of the driving mechanism of the inlet guide vane. CONSTITUTION:In the compression inlet guide vane controller block of a gas turbine control device, during boosting, output signals from a schedule controller 13 and an inlet guide vane controller 14 are inputted to a low value selector 15. A selected signal causes setting of the angle of the compressor inlet guide vane. Meanwhile, at the interior of the inlet guide vane controller 14, a deviation signal between an exhaust gas temperature set signal being an output signal from a rate of change limiter and an exhaust gas temperature actual measurement signal is inputted to a PID computer 14a, and an output signal therefrom is inputted to an upper and lower limit limiter 14b. In this case, an output signal from a setter 14c is added to the deviation signal through a switch 14d. An addition signal and an output signal from a dead zone device 14e are inputted to a change-over switch 14f.

摘要： PURPOSE:To restrain steam flow rate from making a sudden change and keep drum water level from causing abnormality by switching valve opening positions of a steam governor and a steam bypass valve from a variable pressure operation control to a constant pressure operation control when the drum water level has caused abnormality while operating a steam cycle under the variable pressure. CONSTITUTION:A generator 6 is driven in a multi-shaft type combined power plant by supplying to a steam turbine 5 a high temperature and high pressure steam generated at an exhaust heat recovery boiler 4 to where a high temperature gas exhausted from a gas turbine unit 1 is delivered. The valve opening positions of steam governors 9, 10 and steam bypass valves 11, 12 are controlled by a steam cycle control unit 20A where a steam turbine constant pressure operation command signal formation circuit 40 is equipped and which is made to generate a constant pressure operation command signal that will change the steam turbine operation from the variable operation to the constant operation when at least one of the value or the rate of change thereof of the drum water level of the exhaust heat boiler or the water supply flow rate of the exhaust heat recovery boiler or the like has exceeded the prescribed value while the steam turbine is operated under the variable pressure.
