Patent number: 11527942Abstract: A dual-wound machine comprises a dual-wound generator supplying power to two separate powered zones. The generator comprises a wound rotor with a field winding and a stator with two sets of phase windings and a field control loop that controls the excitation voltage applied to the field winding and therefore the magnetic field produced by the rotor, in order to maintain a constant field flux in the generator and mitigate dynamic coupling between the two sets of phase windings when supplying power to unbalanced loads.Type: GrantFiled: March 26, 2020Date of Patent: December 13, 2022Assignees: National Technology & Engineering Solutions of Sandia, LLC, United States of America as represented by the Secretary of the NavyInventors: Lee Joshua Rashkin, Jason C. Neely, Timothy J. McCoy, Norbert H. Doerry

Patent number: 10574056Abstract: A system and method for control of dispatchable resources on an electrical power distribution grid is disclosed. The disclosed method provides improved response to power imbalance based on a communications signal independent of system frequency. The communication signal provides a feed-forward control of dispatchable power resources. A communications network is employed to generate a signal to dispatchable resources that a power imbalance has occurred. Due to fast response power transmission network interfaces associated with the dispatchable resources, the respective resources respond in significantly less time than feedback controlled conventional generators which depend on line frequency sensing. The rapid response mitigates the impact of power imbalances and enables greater penetrations of converter-interfaced power generation units such as renewable energy sources to be connected to the grid.Type: GrantFiled: October 10, 2017Date of Patent: February 25, 2020Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Felipe Wilches Bernal, Jason C.

Patent number: 10228665Abstract: An emulator is described herein, wherein the emulator is configured to emulate a rotary energy generator. The rotary energy generator can be one of a wind turbine, a diesel engine, or a hydrokinetic generator. The emulator includes an electromechanical motor that is mechanically linked to a generator. A motor drive is electrically coupled to the electromechanical motor, and controls torque at a rotor of the electromechanical motor. Electromagnetic torque produced by the generator is estimated, and the motor drive is controlled based upon the estimated generator torque.Type: GrantFiled: February 7, 2014Date of Patent: March 12, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Jason C.

Patent number: 10168674Abstract: A control architecture and associated control methods are under development to allow a single user to control a team of multiple heterogeneous UMS as they conduct multi-faceted (i.e. multi-objective) missions in real time is disclosed. The control architecture is hierarchical, modular and layered and enables operator interaction at each layer, ensuring the human operator is in close control of the unmanned team at all times. The architecture and key data structures are introduced. Two approaches to distributed collaborative control of heterogeneous unmanned systems are described, including an extension of homogeneous swarm control and a novel application of distributed model predictive control. Initial results are presented, demonstrating heterogeneous UMS teams conducting collaborative missions.Type: GrantFiled: April 22, 2014Date of Patent: January 1, 2019Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Stephen Buerger, Joshua Alan Love, Jason C.
