ABSTRACT:
A speed stabilization apparatus for use in a two shaft gas turbine is disclosed which includes a speed detector for detecting a rotational speed of a driving shaft of a turbine for driving a generator, a governer for controlling the amount of fuel supplied to a cumbustor, a plurality of delay circuits for providing load charging delay signals after predetermined time periods from when load charging commands are generated, and a forcible fuel supply control circuit. The governer usually controls the amount of fuel to the combustor in accordance with the detected speed signal from the detector so as to stabilize a rotational speed of the generator. When a load charging command is generated, the forcible fuel supply control circuit causes the governer controlling such that the full amount of fuel in supplied to the combustor. After the predetermined time duration from that, the corresponding charging load is connected to an output of the generator.
