Induction Generator) that is directly connected to the grid through a transformer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Since SCIG always draws reactive power from the grid, this concept uses a capacitor bank for reactive power compensation.<br>A smoother grid connection occurs by incorporating a soft-starter.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Concepts 2 \u2013 variable speed wind

controlled resistance, whose size defines the range of the variable speed.<br>Since the losses are proportional to the slip, a limited slip range is used.<br>As in the Danish wind turbine concepts (concepts 1), the reactive power compensation and a soft starter are required for this concepts.<\/p>\n\n\n\n<h5 class=\"wp-block-heading\">Concepts 3 \u2013 variable speed wind turbine concepts with
