Gearbox Reliability Collaborative Phase 3 Gearbox 3 Test

The GRC uses a combined gearbox testing, modeling, and analysis approach disseminating data and results to the industry and facilitating improvement of gearbox reliability. This test data describes the tests of GRC gearbox 3 in the National Wind Technology Center dynamometer and documents any modifications to the original test plan. It serves as a guide to interpret the publicly released data sets with brief analyses to illustrate the data. TDMS viewer and Solidworks software required to view data files. The National Renewable Energy Laboratory (NREL) Gearbox Reliability Collaborative (GRC) was established by the U.S. Department of Energy in 2006; its key goal is to understand the root causes of premature gearbox failures and improve their reliability.

5.3 Generator Misalignment.zip 26 KB Archive TDMS Files. In Phase 3 testing of GB2, the generator was misaligned up to 3° to assess whether excessive loads were imparted onto the HSS bearings. NOTE: this archive is no longer functional. We apologize for the inconvenience.
5.4 Field Representative.zip 153 KB Archive TDMS Files. Reproduction of field conditions in the dynamometer was achieved in Phase 3 testing of GB2 using the dynamometer variable frequency drive capability. The same normal power production and shutdown cases tests will be repeated for GB3. NOTE: this archive is no longer functional. We apologize for the inconvenience.
5.5 Grid Disconnect.zip 81 KB Archive TDMS Files. Controlled shutdowns tests were also completed on November 3, 2016. While operating at a steady-state power level, the dynamometer was intentionally shut down in a controlled fashion. NOTE: this archive is no longer functional. We apologize for the inconvenience.
