Determining a model of the blade in a wind turbine for regions with low wind speeds

The object of research is the shape blade a vertical-axis installation. problem solved in this work to find optimal for wind power installation operation at low speeds or areas where its flow limited. In course work, interaction between each option and depending on was considered. With help reduced model turbine, flat blade, with «pocket», «pocket» slit were tested. test results prove effectiveness designed manufactured slit. This confirmed by study results, according which, during experiment, number revolutions turbine blades made largest. comparison flat-shaped blades, increase 20 %, and, 10 %. order compare turbines that have slit, experimental studies calculations factor Ср carried out. A flat-blade wheel has Ср1=24; – Ср2=52.9; Cp3=58.7. Therefore, one can assume generated above also largest, Р3=98 W, compared two other shapes blades: flat, P1=32.3 W; Р2=88.2 W. It would time from zero speed reaching constant rotational speed. confirm wheel, which highest rotation over entire period when measurements performed
