Power Flow Control Using Distributed Saturable Reactors

US Patent:
20130320940, Dec 5, 2013
Filed:
Feb 22, 2012
Appl. No.:
13/984196
Inventors:
Aleksandar D. Dimitrovski - Knoxville TN, US
Assignee:
UT-Battelle, LLC - Oak Ridge TN
International Classification:
G05F 1/32
H03F 9/02
US Classification:
323249
Abstract:
A magnetic amplifier includes a saturable core having a plurality of legs. Control windings wound around separate legs are spaced apart from each other and connected in series in an anti-symmetric relation. The control windings are configured in such a way that a biasing magnetic flux arising from a control current flowing through one of the plurality of control windings is substantially equal to the biasing magnetic flux flowing into a second of the plurality of control windings. The flow of the control current through each of the plurality of control windings changes the reactance of the saturable core reactor by driving those portions of the saturable core that convey the biasing magnetic flux in the saturable core into saturation. The phasing of the control winding limits a voltage induced in the plurality of control windings caused by a magnetic flux passing around a portion of the saturable core.

Real-Time Simulation Of Power Grid Disruption

US Patent:
20130191052, Jul 25, 2013
Filed:
Jan 23, 2013
Appl. No.:
13/747779
Inventors:
Steven J. Fernandez - Knoxville TN, US
Mallikarjun Shankar - Knoxville TN, US
James J. Nutaro - Oak Ridge TN, US
Yilu Liu - Knoxville TN, US
Aleksandar D. Dimitrovski - Knoxville TN, US
Olufemi A. Omitaomu - Knoxville TN, US
Christopher S. Groer - Knoxville TN, US
Kyle L. Spafford - Knoxville TN, US
Ranga R. Vatsavai - Knoxville TN, US
International Classification:
G06F 17/00
G01R 21/00
US Classification:
702 60
Abstract:
A method and system for monitoring the electric grid and predicting failures and/or other issues. Streams of data about a power grid are received from a plurality of remote power grid sensors and converted into a univariate time sequence. Anomaly patterns are identified in the univariate time sequence and analyzed or simulated to predict the power grid disruption. The anomaly patterns are compared to power disruption contingencies stored in a database to simulate and/or predict the present or future power disruption represented by the anomaly pattern.

Gapless Core Reactor

US Patent:
20170323717, Nov 9, 2017
Filed:
May 5, 2016
Appl. No.:
15/147630
Inventors:
- Oak Ridge TN, US
Aleksandar D. Dimitrovski - Oak Ridge TN, US
International Classification:
H01F 27/24
Abstract:
A gapless core reactor includes a saturable magnetic core having reactor legs without air gaps and multiple windings. The windings are each wound around a common leg, spaced apart from each other and connected in counter series. The windings are configured such that a magnetic flux generated from an alternating current flowing through the windings generates a plurality of substantially equal and counter magnetic fluxes flowing through two or more separate magnetic circuits.

Harmonic Filter For Magnetic Amplifier

US Patent:
20170324389, Nov 9, 2017
Filed:
May 4, 2016
Appl. No.:
15/146671
Inventors:
- Oak Ridge TN, US
Aleksandar D. Dimitrovski - Oak Ridge TN, US
International Classification:
H03F 9/02
H02J 1/02
Abstract:
A magnetic amplifier includes a permeable core having multiple legs. Control windings wound around separate legs are spaced apart from each other and connected in series in an anti-symmetric relation. Harmonic filters are positioned adjacent to the control windings to attenuate even-ordered harmonics generated by an alternating load current passing through a portion of the legs. The control windings are configured to bias magnetic flux arising from a control current flowing through one of the control windings which is substantially equal to the biasing magnetic flux flowing into a second control winding. The flow of the control current through each of the control windings changes the reactance of the permeable core reactor by driving those portions of the permeable core that convey the biasing magnetic flux in the permeable core into saturation. The phasing of the control winding limits a voltage induced in the plurality of control windings caused by a magnetic flux passing around a portion of the permeable core.

Dc Current Controller For Continuously Variable Series Reactor

US Patent:
20170077799, Mar 16, 2017
Filed:
Sep 9, 2016
Appl. No.:
15/261106
Inventors:
- Oak Ridge TN, US
Burak Ozpineci - Oak Ridge TN, US
Sheng Zheng - Oak Ridge TN, US
Steven L. Campbell - Oak Ridge TN, US
Aleksandar D. Dimitrovski - Oak Ridge TN, US

Fei Yang - Oak Ridge TN, US
International Classification:
H02M 1/32
H02M 3/04
H02M 7/04
Abstract:
A direct current controller includes a rectifier configured to convert alternating current input into a direct current output. A converter electrically coupled to the rectifier generates a converted direct current voltage that regulates a converted direct current from the direct current output of the rectifier and synthesizes an ac component of an alternating current grid to counteract an induced back-emf. A direct current controller central controller coupled to the converter regulates the converted direct current.
