Abstract: (58 Views) |
Induction generator based wind turbines are very vulnerable to malnutrition, especially in low power, during grid side faults. In most studies, a finger is used to protect the rotor - side converter during network faults. New networks require wind turbines that can stay connected in fault conditions and provide the requested capacity. In this paper, a new control system based on ounding fault current has been introduced to protect the two mal nourished induction generator - based wind turbines and the bounding generator - based wind turbine during grid - side faults. The proposed limiting is used on the DC side of the rotor - side converter.the mentioned system solves the problems and eliminates the following problems in the system. The proposed restriction has no significant effect on overall network performance during normal operation. Whenever a fault occurs, whether symmetric or asymmetric, it not only limits the over current of the rotor but also prevents the acceleration of the rotor speed and limits high torque fluctuations even during the zero grid voltage, the simulation results confirm the limiting performance in protecting the wind turbine in grid fault conditions.
