A Novel Crowbar Protection Technique for DFIG Wind Farm during Fault Ride Through
This paper proposes a terminal crowbar protection technique for Doubly Fed Induction Generators (DFIG) to protect the rotor converter and enhance network stability during grid disturbances. Simulation test using MATLAB-Simulink toolbox is implemented on a 9 MW wind farm exports its power to 120 KV grid. The simulation is performed using different values of crowbar resistances. The variations of...
متن کاملLow Voltage Ride Through Enhancement Based on Improved Direct Power Control of DFIG under Unbalanced and Harmonically Distorted Grid Voltage
In the conventional structure of the wind turbines along with the doubly-fed induction generator (DFIG), the stator is directly connected to the power grid. Therefore, voltage changes in the grid result in severe transient conditions in the stator and rotor. In cases where the changes are severe, the generator will be disconnected from the grid and consequently the grid stability will be attenu...
متن کاملFast Coordinated Control of DFIG Wind Turbine Generators for Low and High Voltage Ride-Through
This paper presents a fast coordinated control scheme of the rotor side converter (RSC), the Direct Current (DC) chopper and the grid side converter (GSC) of doubly fed induction generator (DFIG) wind turbine generators (WTGs) to improve the low voltage ride through (LVRT) and high voltage ride through (HVRT) capability of the DFIG WTGs. The characteristics of DFIG WTGs under voltage sags and s...
متن کاملImpact of VSC faults on dynamic performance and low voltage ride through of DFIG
A doubly-fed induction generator’s (DFIG’s) sensitivity to external faults has motivated researchers to investigate the impact of various grid disturbances, such as voltage sags and short circuit faults, on its low-voltage ride-through (LVRT) capability. However, no attention has been paid to the impact of internal faults in voltage source converters (VSCs), that interface a DFIG with the grid,...
متن کاملLow voltage ride-through capability improvement of DFIG-based wind turbines under unbalanced voltage dips
This paper proposes a competent and effective scheme to enhance the ride-through capability of DFIGbased wind turbines under unbalanced voltage dip conditions. The proposed method is realized through joint use of the rotor-side converter control and a three-phase stator damping resistor (SDR) placed in series with the stator windings. By means of an asymmetrical SDR idea, during the unbalanced ...
