US Patent:

20120271574, Oct 25, 2012

Filed:

Apr 19, 2011

Appl. No.:

13/089435

Inventors:

Michael Jack Swan - Woodstock GA, US

Assignee:

Southern Company Services, Inc. - Atlanta GA

International Classification:

G06F 19/00

US Classification:

702 60

Abstract:

Various methods and systems are provided for impulse response monitoring in power systems. In one embodiment, a method includes obtaining raw power system data associated with a power system, cross-correlating the raw power system data with a synchronized pseudo-random sequence signal injected into the power system to determine a correlated impulse response and determining a condition of the power system based at least in part upon the correlated impulse response. In another embodiment, a system includes a plurality of signal injection systems and a data capture device coupled to a power system. A data analysis device cross-correlates raw power system data obtained by the data capture device with at least one synchronized pseudo-random sequence signal injected by a signal injection system and determines a condition of the power system based at least in part upon a frequency spectrum based upon a correlated impulse response.

Abstract:

Various methods and systems are provided for monitoring and analysis of electrical components. In one embodiment, a method includes obtaining raw radio frequency (RF) component data associated with an electrical component, cross-correlating the raw RF component data with a synchronized pseudo-random sequence (PRS) signal injected into the electrical component to determine a correlated impulse response, and determining a condition of the electrical component based at least in part upon the correlated impulse response. In another embodiment, a system includes a signal injection system coupled to an electrical component. The signal injection system injects a synchronized PRS signal into the electrical component. A data capture device obtains raw RF component data synchronized with the PRS signal through a RF antenna. A data analysis device cross-correlates the raw RF component data with the PRS signal to determine characteristics associated with the electrical component.
