Fault ride-through capability analysis of grid connected wind-DFIG system using SFCL & DVR Available to Purchase

The behaviour of the power system varies as the wind power penetration increases. Wind turbine generators must adhere to essential grid code, which requires them to maintain grid connectivity even in the event of an abnormal circumstance. In this study, a unique wind energy conversion system (WECS) based on a doubly fed induction generator is suggested, which includes a superconducting fault current limiter (SFCL) and a dynamic voltage restorer (DVR). The DVR improves the power quality of the system and increases its Low Voltage Ride through (LVRT) capability. By utilizing SFCL, fault current can be reduced effectively, which lowers the cost of high capacity circuit breaker. In this study, a resistive SFCL is developed to enhance the power system’s Fault Ride through (FRT) capability. It is also required to maintain the DC link capacitor voltage stable in DFIG based WECS. Additionally, this study employs a PID controller to lessen DC link voltage fluctuations during faults. All of these processes have been modelled with the aid of a simulation programme that uses MATLAB and built in Simulink library components.
