Improvement of Fault Ride-Through Capability of Grid Connected Wind Turbine Based on a Switched Reluctance Generator Using a Dynamic Voltage Restorer

This paper presents an improvement to the fault ride-through (FRT) capabilities for a wind turbine that employs switched reluctance generator (SRG) using dynamic voltage restorer (DVR). The may be disconnected from grid by sag, swell, and faulty line in grid. To improve stator of SRG during failures, DVR is applied inject at point common coupling (PCC) into voltage. A control strategy based on fuzzy logic controller (FLC) proposed this study FRT capability meet codes while avoiding disconnection MATLAB/SIMULINK simulation validated effectiveness performance approach under three test cases: balanced unbalanced single line-to-ground fault. In addition, total harmonic distortions utilizing different controllers were compared sag mode. Furthermore, results exhibited significant transient steady-state response, thus verifying traditional methods.
