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 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 کاملInfluence of Fault Current Limiter in Voltage Drop and TRV Considering Wind Farm
Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does...
متن کاملEnhancement of Fault Ride through Capability of a Wind Driven Dfig Connected to the Grid
Enhancement of fault ride-through (FRT) capability and subsequent improvement of rotor speed stability of wind farms equipped with doubly fed induction generator (DFIG) is the objective of this paper. The objective is achieved by employing a novel FRT scheme with suitable control strategy. The proposed FRT scheme, which is connected between the rotor circuit and dc link capacitor in parallel wi...
