Abstract
In order to overcome the disadvantages of S-VAWT mentioned above, a straight-bladed vertical axis wind turbine with a directed guide vane row has been proposed and tested by the authors. According to previous studies, it was clarified that the performance of the straight-bladed vertical axis turbine can be improved by means of the directed guide vane row. However, field test of the proposed wind turbine has not been carried out so far. In the study, performance of straight-bladed vertical axis wind turbine with a directed guide vane row was investigated experimentally in field. As a result, it has been clarified that the guide vane row is effective equipment for improving the turbine performance and the power coefficient of turbine depends on time interval of control of guide vane row.
