The paper describes control of wingtip vortices generated by vertical type Magnus wind turbine. The wind turbine consists of three circular cylinders. Each cylinder rotates on its own vertical axis and moves in orbit. Wingtip vortices cause decrease of power generation capacity and aerodynamic noise. Therefore, the study aims to control wingtip vortices. Numerical study was conducted for 14 models to find out control factors to suppress wingtip vortices. Consequently, two devices are found most effective. One is the protection plates placed at both end of the cylinder blades, and the other is curved wings placed along the cylinder blades.
