To further demonstrate the applicability of the brushless doubly-fed induction generator to wind turbine applications, a grid synchronization procedure is developed. Vector control of the converter-side stator winding is used to induce a voltage on the grid-side stator winding. A detector is developed to automatically connect the machine to the grid when the voltages are synchronized. Experimental results show that synchronization occurs within 0.4 seconds while the rotor is accelerating.
