Two-Shaft Gas Turbine

摘要

A two-shaft gas turbine having high operability is provided. The two-shaft gas turbine includes: a gas generator having a compressor, a combustor and a high pressure turbine; a power turbine having a low pressure turbine; a load connected to the power turbine; a motor/generator capable of rotatably driving the gas generator and capable of extracting power from the gas generator; electric equipment controlling the rotational driving and the power extraction by delivering electric power between the electric equipment and the motor/generator; and a control device controlling the electric equipment, wherein the combustor has a plurality of combustion regions to which a fuel is supplied through fuel adjustment means which are independent from each other, and the control device controls a delivery amount of the electric power delivered by the electric equipment corresponding to the number of combustion regions to which the fuel is supplied.

1. A two-shaft gas turbine comprising:
a gas generator including a compressor which compresses air, a combustor which adds a fuel to compressed air obtained by compressing air with the compressor, and combusts a fuel-air mixture thus generating a combustion gas, and a high pressure turbine which is rotatably driven by the combustion gas; a power turbine which has a low pressure turbine rotatably driven by the combustion gas which drives the high pressure turbine; a load which is connected to the power turbine; a motor/generator which is capable of rotatably driving the gas generator and is capable of extracting power from the gas generator; electric equipment which controls the rotational driving and the power extraction by delivering electric power between the electric equipment and the motor/generator; and a control device which controls the electric equipment, wherein the combustor has a plurality of combustion regions to which a fuel is supplied through fuel adjustment means which are independent from each other, and the control device controls a delivery amount of the electric power delivered by the electric equipment corresponding to the number of combustion regions to which the fuel is supplied.
