Abstract: A spark ignition system for a gas turbine electronically controls the cycle of charge and discharge of a spark generator of the capacitive type. There is a function generator (5) which derives a reference voltage as a function of the speed of the turbine and possibly of other parameters. A charge control (6) for the capacitive cell (9) and a spark frequency control (7) are controlled by the reference voltage. Reignition in the case of flame extinction is controlled by an opto-electronic arrangement (11, 12, 13) which drives a reignition circuit (14), when flame extinction is detected. The reignition circuit produces a voltage which is superimposed on and over-rides the speed reference voltage to activate the system to produce ignition at a start condition.The system can be used for ignition of a gas turbine, especially a turbo-compressor.
