A New Method to Enhance the Low Voltage Ride Through Capability of Doubly Fed Induction Generator Using Resistive Type Superconducting Fault Current Limiter
In the event of voltage sag at the nearing of a wind park, severe currents may pass through the power electronic devices of the Doubly Fed Induction Generators (DFIGs). Hence, according to the Low Voltage Ride Through (LVRT) requirements, the wind parks are allowed to disconnect from the network after a certain time. Therefore, to avoid such actions, the LVRT requirement of wind parks is consid...
متن کاملImprovement of Low Voltage Ride – through Capability of Distributed Generation in a Microgrid Using Superconducting Fault Current Limiter
Although the introduction of distributed generation (DG) in a distribution system improves the power quality of power system, it increases the fault current level reducing voltage at point of common-coupling (PCC). Hence, there is a need of improving fault ride-through (FRT) capability to avoid sudden tripping of DG units from the utility grid during voltage sag in a faulty condition. In this p...
متن کاملWind Turbine Control Design to Enhance the Fault Ride- Through Capability
This paper presents a control strategy for wind turbines to enhance their fault ride-through capability. The controller design is based on pitch controlled variable speed wind turbine equipped with doubly-fed induction generator (DFIG). The fault ride-through is realized by injecting a crowbar with variable resistance on the generator rotor circuit. To reduce the mechanical loads induced by gri...
متن کاملCoordination between Fault-Ride-Through Capability and Over-current Protection of DFIG Generators for Wind Farms
Fault Ride-Through (FRT) capabilities set up according to the grid codes may affect the performance of related protective elements during fault periods. Therefore, in this paper the coordination between the FRT capability and over-current protection of DFIG Wind Generators in MV networks is investigated. Simulation test cases using MATLAB-Simulink are implemented on a 365-MW wind farm in AL-Zaa...
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...
