초록
Remote islands, off-grid to the mainland, rely on diesel generation for own electricity supply. In order to decrease carbon gas production, diesel generation should be minimized and renewable energy applications such as wind energy and solar energy should be expanded. In this study, a nacelle cover for a 200 kW wind power generator for an energy independent island was designed and its structural safety was analyzed. Stress, deformation and buckling were analyzed for each load case according to the GL Guidelines. As a result, the maximum deformation was 12.99 mm by rear wind (load case 4), the maximum von Mises stress was 96.89 MPa by left wind (load case 3) and the safety factor was more than 2.58 in all load cases. In addition, the critical buckling strength value (safety factor) was 2.04 for the lowest value in rear wind (load case 4). The structural safety of the nacelle cover design was confirmed.
