    • PURPOSE:To improve control reliability by performing in parallel the control of program set value and the control of a fixed value in acceleration, in acceleration control of a gas turbine, and determining the acceleration control value from the minimum value between the both. CONSTITUTION:In the starting control system 8 which constitutes a part of the control apparatus for a gas turbine, the real speed value from a speed detector 21 is entered into a calculator 22 and an integrator 24. The speed of the gas turbine is compared with the set value according to the lapse of time by a function generator 23 and the calculator 22, and the flow rate of fuel is determined according to the deviation signal. The speed signal is integrated by the integrator 24, and converted to an acceleration signal. The acceleration signal is compared with the set value in a calculator 25, and the fuel amount is determined according to the deviation signal. Out of the fuel rate dicision signals from two systems described above, the lower value signal is selected by a minimum value selecting circuit 26, and transmitted as the final fuel rate decision signal 27 from the control apparatus.

    • PURPOSE:To obtain high reliability by making dual systems as velocity/load controlling system and temperature controlling system, by facilitating to make consecutive controls even when there is something wrong in one system, and by providing functions of monitoring and managing said dual systems in a start controlling system. CONSTITUTION:Signals by a detector 2 to detect temperature, velocity, pressure and various contact conditions set on a gas turbine body 1 makes signal transformation by input devices 3a-3c in a controller, input is given to microcomputers 4-6 in A-C systems. Control signals from microcomputers 4, 5 in A and B systems are transmitted through a bus 7 to an output device 8, where they are made signal transformation to drive an actuator 9 in a fuel controller. Information transfer is made between microcomputers through a bus 10a, each information performs communication between man and machine with use of an operation console 11, a display device 12, a typewriter 13 and a host computer 14 by the microcomputer 6 in C system.
