Devices and methods for harvesting power from arrays of wind turbines

摘要

Variable frequency alternate current (VFAC) bus arrangements and systems using such VFAC bus arrangements are described, such as arrays of turbines. Such systems have a centrally located power process hub connected to the VFAC bus arrangements in a way that there is a dedicated VFAC bus arrangement for each turbine of the array.

主权项

1. A system, comprising:
an array arrangement of turbines disposed along plurality of nodes, each node associated to n turbines, with n=0, 1, 2, ith a plurality of variable frequency alternating current (VFAC) buses, each VFAC bus comprising:
a first terminal configured to be connected to a generator attached to a turbine; anda second terminal configured to be connected to an alternating current (AC) to direct current (DC) converter;wherein each VFAC bus is configured to transfer variable frequency alternating current (VFAC) power generated by the generator connected to the first terminal from mechanical power of the corresponding attached turbine to the AC to DC converter connected to the second terminal, wherein, during operation, each VFAC bus transfers VFAC power generated by the generator attached to a corresponding turbine and connected to the first terminal of the VFAC bus to the AC to DC converter connected to the second terminal of the VFAC bus, and a power process hub, wherein each of the AC to DC converters connected to the second terminal of each VFAC bus is located inside the power process hub.
