| Popis: | Despite new efforts to improve wind turbine (WT) reliability are constantly made in every subsystem of the Megawatt large WTs, small wind turbines (SWT) lack of reliability and Conditioning Monitoring (CM), probably due to economic considerations. Here, an analysis of field test data for a self-made SWT with a direct drive, slot-less, concentrated winding, Axial Flux Permanent-Magnet Generator (AFPMG) is presented. A broken blade fault event is also analyzed and a simple condition monitoring algorithm using the dc bus signals is proposed. This analysis shows that the mechanical nature of the described fault makes a slow sampling rate algorithm suitable for CM systems for SWTs. |
