摘要： PROBLEM TO BE SOLVED: To maintain a stable combustion state by checking a loss of kinder. SOLUTION: Output from a comparator 45 is turned on, and output from a flip-flop FF 49 is turned on when the fuel nozzle pressure ratio NPR reaches the given pressure ratio VRA or less. A signal selector 41 is switched to a ratio setting device 39 side to select a ratio setting total closing signal RA. A fuel flow rate control signal FSRDL for diffusion combustion in a first system decreases with the given rate to zero, entirely closing a fuel flow rate control valve GCVL. A fuel flow rate control signal FSRD for diffusion combustion comes to equal to a fuel flow rate control signal FSRDH for diffusion combustion in a second system. Thus, fuel for diffusion combustion passes through a fuel flow rate control valve GCVLH only in the second system. The fuel nozzle pressure ratio in the second system is maintained to the given value VRA or more even for a decrease in the diffusion fuel flow rate caused by a succeeding increase in a load, and an elevation in combustion gas temperature.

摘要： PROBLEM TO BE SOLVED: To protect a gas turbine plant from damage by an excessive temperature by imparting an opening limiting value of a fuel pressure control valve on the basis of opening of a fuel flow control valve, and performing a gas turbine trip when opening of the fuel pressure control valve exceeds the opening limiting value in ignition operation of a combustor. SOLUTION: In a gas turbine controller for feeding combustion gas to a gas turbine 8 by mixedly burning delivery air from an air compressor 2 and fuel fed from fuel piping by a combustor 4, a fuel pressure control valve 5 is interposed in primary side fuel piping of a fuel flow control valve 6 arranged in the fuel piping. This fuel pressure control valve 5 is controlled by the gas turbine controller 11 according to output of a first pressure detector 18 for detecting primary side fuel pressure to control the primary side fuel pressure to set an opening limiting value of the fuel pressure control valve 5 on the basis of opening of the fuel flow control valve 6 at this time. When opening of the fuel pressure control valve 5 exceeds the opening limiting value in ignition operation of the combustor 4, a feed of fuel is cut off.

摘要： PROBLEM TO BE SOLVED: To provide a gas turbine controller contributing to stabilizing system frequency if the system frequency varies transiently, without having to set the material strength of gas turbine high-temperature components below the maximum stress of the high-temperature components.
SOLUTION: Control of gas-turbine combustion gas temperature is excluded so that, if a system frequency error is detected, adjusting the output of the gas turbine contributes to recovering the system frequency. For this, the gas turbine controller has a logic circuit which excludes the control of gas turbine combustion gas temperature according to a signal coming from the function of detecting system frequency errors, and a circuit which restores the gas turbine when the turbine is usable. The detection of system frequency errors may be effected by receiving external signals or by providing the controller in a combined cycle plant.

摘要： PURPOSE: To perform operation of gas turbine with gas turbine efficiency increased to a high value while the thermal stress of a gas turbine is prevented from generation even when the fluctuation of a system frequency is produced by a method wherein an exhaust gas temperature control signal or a load limit control signal is selected as a fuel control signal. CONSTITUTION: During ordinary running, an exhaust gas temperature control signal FT or a load limit control signal FLL produces a fuel control signal FREF. Since a speed load control signal FN follows in a position higher by a margin value FBA than an exhaust gas temperature control signal FT or a load limit control signal FLL, the speed load control signal FN is lowered from a position higher by the margin value FBA and even when it is selected as the fuel control signal, rapid disturbance does not occur. Further, when a fuel flow rate is adjusted by means of the exhaust gas temperature control signal FT, even when the exhaust gas temperature control signal FT is rapidly increased, the speed load control signal FN follows only at a maximum follow rate determined by the upper limit set value of an upper limiter 46, the rapid change of a fuel flow rate is suppressed.

摘要： PURPOSE:To improve the operational property by controlling the fuel amount to a specific minimum fuel amount for a specific time responding to the minimum fuel amount test instruction in a turbine operation to make it possible to confirm the maintaining of the flame, and making it possible to restore the fuel amount and the gas turbine speed to the values before the test instruction. CONSTITUTION:When a minimum fuel test is instructed in a normal operation, a contact 9a is opened, a contact 9b is closed, and a contact 9c is converted to the (b) side. As a result, while the then fuel requirement amount is maintained by an integrator 6d, the fuel requirement amount less than the minimum fuel from a setter 17 is delivered to an accidental fire preventive limiter 10. And, depending on this fuel requirement amount, a fuel control valve 5 is controlled to operate a combustor 4, and the accidental fire preventive function is confirmed. After that, since the fuel requirement amount output from a speed/load control circuit 7 is increased by the decrease of the shaft speed, the original fuel requirement amount maintained by the integrator 6d is output from a low valve selection circuit 8, and the fuel amount after the test is restored to the value before stopping the normal operation.

摘要： PURPOSE: To prevent cabitation by furnishing a function generator to generate a limitation value, which is to limit the revolving speed of a boiler service pump in accordance with the outlet pressure to a range which assures free of generation of cabitation.
CONSTITUTION: At a function generator 16 which is to give the pump revolutions limitation value NL in response to the outlet pressure P of a water service pump, the output NL is subtracted from the number-of-revolutions reference signal NR to be fed into a turbine governor 14, and the difference (NR-NL) is subtracted from the input (Q-QR) of integral element 13 through a non-linear element 17. Thereby the revolving speed of the water service pump, which is particularly used with variable pressure, can be controlled within a range which is free from generation of cabitation.
