Dynamic Modeling of Wind Turbines Based on Estimated Wind Speed under Turbulent Conditions
Large-scale wind turbines with a large blade radius rotates under fluctuating conditions depending on the blade position. The wind speed is maximum in the highest point when the blade in the upward position and minimum in the lowest point when the blade in the downward position. The spatial distribution of wind speed, which is known as the wind shear, leads ... إقراء المزيد

Optimal Control of an Autonomous Variable Speed Wind Generation System based on Bacteria Foraging Optimization Technique
A developed control strategy for an isolated wind generation unit is presented. The proposed system mainly consists of an induction generator driven by a wind turbine, synchronous machine, consumer load, discrete dump load, and gate turn-off thyristor based power electronics converter. Two control loops are used in this study. The first regulates the load bus voltage based on the excitation ... إقراء المزيد

Advanced protection schemes for DFIG based wind turbines during the grid faults

Advanced protection schemes for DFIG based wind turbines during the grid faults
Negative impacts of the grid faults in the Doubly Fed Induction Generators (DFIGs) based wind turbines systems include the stator and rotor over currents, DC-link over voltage, electromagnetic torque oscillations, active and reactive power fluctuations at the grid connection point, potentially leading to destabilization of the power system network. For eliminating of the negative impacts, thus enhances the DFIGs based ... إقراء المزيد

Improved Protection Schemes for DFIG Based Wind Turbines during the Grid Faults
Abstract: There are many negative impacts of the grid faults in Doubly Fed Induction Generators (DFIG) based wind turbines such as stator and rotor over currents, DC-link over voltage, electromagnetic torque oscillations, active and reactive power fluctuations at the grid connection point. Negative impacts of the grid faults have potentially led to destabilization of the power system network. Eliminating the ... إقراء المزيد
