Patent number: 9876412Abstract: A drive system for driving a load, comprising a gas turbine configured and arranged for driving the load, an electric motor/generator electrically connected to an electric power grid, a first load coupling connecting the gas turbine to the load, a second load coupling, connecting the load to the electric motor/generator. The electric motor/generator 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 load. The drive system comprises furthermore a disconnecting device to reversibly disconnect the load from the gas turbine, so that the load can be driven only by the motor.Type: GrantFiled: May 29, 2014Date of Patent: January 23, 2018Assignee: Nuovo Pignone SrlInventors: Marco Santini, Marco De Iaco
