Abstract
Disclosed is a method for operating a drive train having a drive shaft (2), an electric prime mover (4) connected to an electrical grid (12), and a differential gearing (3) having a total of three input and output elements, an output element being connected to the drive shaft (2), one input element to the prime mover (4) and a second input element to a differential drive (5). According to said method the differential drive (5) is motor-operated only, whereas the prime mover (4) is motor- or generator-operated, the differential drive (5) being coupled to the electrical grid (12) by way of a rectifier (19).
Claims10
A method for operating a drive train with a drive shaft, an electrical prime mover that is connected to a power grid, and a differential gear system with three inputs and outputs, one output being connected to the drive shaft, a first input being connected to the prime mover, and a second input being connected to a differential drive, the method comprising:
- only operating the differential drive as a motor, while the prime mover is operated as a motor and while the prime mover is operated as a generator.
A drive train comprising:
- a drive shaft;
- an electrical prime mover that is connected to a power grid;
- and
- a differential gear system with three inputs and outputs, one output being connected to the drive shaft, a first input being connected to the prime mover, and a second input being connected to an electrical differential drive,
- wherein the differential drive is connected to the power grid via a rectifier that is a grid-side inverter and installed such that the differential drive is only configured to be operated as a drive and not as a generator.
