  • Patent number: 10174630
    Abstract: A drive system for driving at least one compressor is described. The system comprises a gas turbine configured and arranged for driving the compressor. The gas turbine has a hot end and a cold end. A load coupling for connection of said gas turbine to the compressor is arranged at hot end of the gas turbine. An electric motor/generator arranged at the cold end of the gas turbine. The electric motor/generator is electrically connected to an electric power grid and is adapted to function as a generator for converting excess mechanical power from the gas turbine into electrical power and delivering the electrical power to the electric power grid, and as a motor for supplementing driving power to the compressor.
