The classical 'Danish Concept' describes a wind turbine consisting of a stall-controlled rotor with three rotor blades, a gearbox, a pole-switched asynchronous generator with squirrel cage rotor and a direct mains grid coupling. In order to limit the inrush currents that are produced when the generator is coupled with the grid, soft-starters are used between the generator and the grid during the starting period.
