System And Method For Monitoring Wind Turbine Gearbox Health And Performance
System And Method For Monitoring Wind Turbine Gearbox Health And Performance
US Patent:
2012002, Feb 2, 2012
Filed:
Jul 30, 2010
Appl. No.:
12/847209
Inventors:
HUAGENG LUO - CLIFTON PARK NY, US
DARREN LEE HALLMAN - SCOTIA NY, US
ROBERT ARVIN HEDEEN - CLIFTON PARK NY, US
MICHAEL SIRAK - ERIE PA, US
DENNIS RICHTER - LAWRENCE PARK PA, US
DARREN LEE HALLMAN - SCOTIA NY, US
ROBERT ARVIN HEDEEN - CLIFTON PARK NY, US
MICHAEL SIRAK - ERIE PA, US
DENNIS RICHTER - LAWRENCE PARK PA, US
Assignee:
GENERAL ELECTRIC COMPANY - SCHENECTADY NY
International Classification:
H02P 9/04, G06F 19/00
US Classification:
290 44, 702 34
Abstract:
A system and method are provided to monitor the health and performance of a wind turbine gearbox. A plurality of sensors coupled to the wind turbine gearbox provide input to a controller. The controller generates output information that includes performance and health information of the wind turbine gearbox based on the input received from each of the sensors.

International Classification:
G06F 19/00
US Classification:
702 34
Abstract:
A system and method are provided to monitor the health of a wind turbine gearbox. The system includes a plurality of sensors coupled to the wind turbine gearbox and a controller coupled to the plurality of sensors. The controller is configured to acquire vibration information from a vibration sensor, acquire a tachometer signal, convert the tachometer signal and the vibration information into a cycle domain signal, and perform an order analysis on the cycle domain signal, the order analysis providing information that identifies potential and actual damage within the wind turbine gearbox.

International Classification:
G01R 33/12
US Classification:
324239
Abstract:
A method for determining a case depth of a hardened layer in a surface of a metal object includes: (a) placing an eddy current probe at a location adjacent the surface; (b) using the eddy current probe, generating a time-varying eddy current in the object; (c) using the eddy current probe, outputting a measured eddy current and providing a signal representative of the measured eddy current to a computer; (d) using the computer, comparing the time-varying measured eddy current to a correlation of measured eddy currents to known case depths; and (e) determining the case depth at the location of the probe based on the correlation.
