Gaseous fuel compression and control system for gas turbine engine.

摘要

A gaseous fuel compression and control system for a gas turbine engine (30) comprises a screw compressor (10) driven by an electric motor (11) for feeding gaseous fuel to the gas turbine engine, and a modulating device (12) for modulating the rotational speed of the motor by controlling the frequency of electric power to the motor in response to sensed output power of the gas turbine engine.
