The Doubly Fed Induction Generator DFIG wind turbines are the most chosen for the grid connection thanks to its dynamic, but the disconnection of these wind turbines during line fault to protect its converters don’t conform the new grid codes which prohibit disconnection of wind turbine during line fault, and recommend them to contribute in grid stability. This paper proposes a new model of DFIG wind turbine connection between them, where the number of converters in grid side is reduced and the connection of wind turbines in parallel to the grid is transformed to series-parallel connection, the aim of this new model of connection are to reduce the converters number in the grid side, limit current transient in converters, double the voltage, and reduce the investment cost. The total power generated by the farm before this new connection will be kept unchanged thanks to the installed switch in the model, a fuzzy logic program is developed to control switches.
