PROJECT TITLE :

Asymmetric Fault Ride through Capability Enhancement of DFIG Based Variable Speed Wind Generator by DC Resistive Fault Current Limiter - 2016

ABSTRACT:

Doubly fed induction generator (DFIG) based mostly variable speed wind generator is vulnerable to any sort of grid fault, because the stator of the DFIG is directly connected to the grid. Likewise the symmetrical faults, the asymmetrical faults conjointly might cause the DFIG face high mechanical stress that might lead to mechanical injury. Therefore, it is terribly vital to research the fault ride through (FRT) capability of the DFIG system during the asymmetrical fault things. During this work, in order to enhance the FRT capability of the DFIG primarily based wind generation system, a DC resistive superconducting fault current limiter (SFCL) is proposed. The performance of the DC resistive SFCL is compared to that of the bridge kind fault current limiter (BFCL). Simulations are accomplished by using the Matlab/Simulink software. Simulation results clearly indicate that the proposed DC resistive SFCL improves the FRT ability of the DFIG primarily based variable speed wind generator system during any type of asymmetrical faults in the facility network. Conjointly, the performance of the proposed methodology is better than that of the BFCL.
