Abstract :
The transient behavior of a wind-driven induction generator after its disconnection from the power grid is investigated. Measurements on an experimental arrangement, followed by theoretical analysis, show that self-excitation always occurs when there is torque and the generator is compensated. Over a wide range of compensation power, the self-excitation voltage does not change significantly. Suggestions for protection against self-excitation are made
