Abstract
A power plant assembly, including—a turbine for driving at least one rotor shaft; —a combustion chamber for generating drive energy for the turbine; —at least one electric machine which is coupled to the rotor shaft and can be operated both in a generator mode and in a motor mode; —and at least one energy storage system which is connected to the electric machine and can store energy generated by the electric machine when the electric machine is in generator mode. A set of control electronics of the power plant assembly is configured to operate the combustion chamber using a lean fuel-air mixture and, for this purpose, to selectively operate the at least one electric machine in generator mode or in motor mode, depending on the power to be applied by the power plant assembly.
