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 test device of a plant controller for easily turning the operation state of a gas turbine plant to a desired operation state and easily switching a actual valve unit and a simulation model. SOLUTION: The control state amount and test items of the plant controller and a plant simulator are stored in a data storage means 57. A test item selection means 58 selects the test item stored in the data storage means 57 at the time of testing the plant controller and a state setting means 59 sets the control state amount to the plan controller and the plant simulator so as to be the operation state of the test item selected in the test item selection means 58. Thus, the operation state of the test item is reproduced.

摘要： PROBLEM TO BE SOLVED: To provide a gas turbine control device by which a stable speed/load control operation can be performed without causing a motoring operation for a power generator even when a system frequency fluctuates during the change of a combustion mode in a load increase or during an initial load is held. SOLUTION: This gas turbine control device which outputs the fuel command signal for a gas turbine by obtaining a speed/load control signal from the deviation between a governor setting signal and the speed signal of the gas turbine, is provided with a storage means for storing a gas turbine speed, and a means for generating a speed/load controlling and compensating signal which compensates the speed/load control signal based on the deviation between the stored value for gas turbine speed signal outputted from the storage means and an actual gas turbine speed.

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 provide a control device and a control method of a gas turbine, capable of optimally maintaining the fuel distribution ratio of a diffusion combustion fuel and a premixed combustion fuel and maintaining a stable combustion state without occurrence of combustion vibration even when the load of the gas turbine abruptly changes. SOLUTION: The control device of a gas turbine is provided with a calculating unit 30 to calculate combustion gas temperature TF and a combustion gas temperature correction part 50 to output a combustion gas temperature TFX nearer to a true value by correcting the calculated combustion gas temperature TF. The fuel distribution ratio of the diffusion fuel and the premixed fuel fed to a combustor 4 is controlled on the basis of the corrected combustion temperature TFX. COPYRIGHT: (C)2006,JPO&NCIPI
