GAS TURBINE IN MECHANICAL DRIVE APPLICATIONS AND OPERATING METHODS

摘要

A drive system for driving at least one compressor is described. The system comprises a gas turbine (101) configured and arranged for driving the compressor (103). The gas turbine has a hot end (101H) and a cold end (101C). A load coupling (105) for connection of said gas turbine (101) to the compressor (103) is arranged at hot end (101H) of the gas turbine (101). An electric motor/generator (111) arranged at the cold end (101C) of the gas turbine. The electric motor/generator (111) is electrically connected to an electric power grid (G) and is adapted to function as a generator for converting excess mechanical power from the gas turbine (101) into electrical power and delivering the electrical power to the electric power grid (G), and as a motor for supplementing driving power to the compressor (103).
