Abstract
Aspects of the present disclosure are generally directed to configurations of power conversion systems for wind turbine generators. For example, certain aspects are directed to a multi-rotor wind turbine. The multi-rotor wind turbine generally includes a plurality of rotors, each coupled to a plurality of electrical generators, one or more machine-side converters, MSCs, coupled to the electrical generators of each of the plurality of rotors and configured to generate at least one direct-current, DC, signal, and one or more line-side converters, LSCs, coupled to the MSCs and configured to generate at least one AC signal based on the at least one DC signal.
Claims15
A multi-rotor wind turbine, comprising:
- a plurality of rotors each having at least one blade mounted thereon, each of the plurality of rotors being coupled to a plurality of electrical generators;
- a plurality of machine-side converters (MSCs), wherein each of the plurality of MSCs is coupled to at least two of the plurality of electrical generators and configured to generate direct-current (DC) signals;
- and
- a line-side converter (LSC) coupled to the plurality of MSCs and configured to generate at least one AC signal based on the DC signals.
A wind turbine generator, comprising:
- a rotor on which at least one blade is mounted;
- a plurality of electrical generators coupled to the rotor;
- a plurality of switches, each coupled to a respective one of the plurality of electrical generators at a first end;
- a machine-side converter (MSC) coupled to a second end of each of the plurality of switches and configured to generate at least one direct-current (DC) signal;
- and
- a line-side converter (LSC) coupled to the MSC and configured to generate at least one AC signal based on the at least one DC signal.
A method of assembling an electrical system for a multi-rotor wind turbine, comprising:
- coupling a plurality of electrical generators to each rotor of the multi-rotor wind turbine, wherein at least one blade is mounted on each rotor;
- coupling each of a plurality of machine-side converters (MSCs) to at least two of the plurality of electrical generators, wherein the plurality of MSCs are configured to generate direct-current (DC) signals;
- and
- coupling a line-side converter (LSC) to the plurality of MSCs;
- wherein the LSC is configured to generate at least one AC signal based on the DC signals.
