Transient Stability of a Grid Connected Induction Generator by changing resistance
Keywords:Induction Generator, Transient Stability, Plugging Mode Operation.
This paper deals with increasing the temporary stability of a grid-connected squirrel cage induction generator. Induction generators are widely used in most wind power generation due to its reliability and low cost. A fault occurs in the electrical system, which increases the speed and voltage instability of the induction generator. Rotor speed is high when the fault is obvious, causing the system to become unstable. A special feature of induction machines is that they reverse the direction of rotational flow, to improve stability. After the error is cleared, the operating mode of the induction machine is changed from product to plugging mode for a short time. This suggests that the proposed method is effective in increasing temporary stability.
