Assignee: GENERAL ELECTRIC COMPANY
Field: Electrical machinery, apparatus, energy (Electrical engineering)
Classification: CPC H  Y | IPC H

Claim 14:
15. A system for operating power generating asset, the system comprising:
a double fed generator connected to a power grid; and
a controller communicatively coupled to the generator, the controller comprising at least one processor and a plurality of modules configured to perform a plurality of operations, the plurality of operations comprising:
determining a non deliverable component and a deliverable component of a total power output of the generator,
determining, via a compensation module of the controller, a first control signal based, at least in part, on the non deliverable component, the first control signal being configured to establish a modified rotor current set point,
determining, via a buffer control module of the controller, a buffer control signal for a DC energy buffer based, at least in part, on the non deliverable component, the DC energy buffer being operably coupled between a line side converter and a rotor side converter of the power converter, wherein determining the buffer control signal further comprises:
filtering, via a conditioning module of the buffer control module, the non deliverable component; and
applying, via the conditioning module, at least one limit to the buffer control signal based on a maximum rating or a minimum rating of a component of the power generating asset,

precluding delivery of the non deliverable component to an electrical grid by delivering the non deliverable component to the DC energy buffer via the line side converter in response to the first control signal and the buffer control signal, and
delivering the deliverable component of the total power output of the generator to the electrical grid.
