GAS TURBINE SYSTEM AND METHOD

摘要

A fuel supply system includes a first fuel gas compressor coupled to a fuel gas compressor shaft and configured to pressurize a fuel for a gas turbine system. A clutch is coupled to the fuel gas compressor shaft and is configured to selectively engage the fuel gas compressor shaft with a turbine shaft of the gas turbine system. An electromechanical machine is configured to operator as a motor to drive the fuel gas compressor shaft or to operate as a generator driven by the turbine shaft to generator power, based on an operating condition of the gas turbine system.

1. A gas turbine system, comprising:
a compressor configured to compress an oxidant; at least one fuel gas compressor configured to compress fuel; a combustor configured to combust a mixture of the oxidant and the fuel into combustion products; a turbine configured to rotate a shaft using the combustion products, wherein the shaft is coupled to the compressor, the at least one fuel gas compressor, and the turbine; and an electromechanical machine configured to selectively operate as a motor to drive the shaft in a motor mode and to operate as a generator driven by the shaft to generate power in a generator mode, based on an operating condition of the gas turbine system.
