Improvement of LVRT Capability of Wind Farms by Using SMES and ‎R-Type BFCL

Fulfillment the Low-voltage ride-through (LVRT) is required for wind farms (WFs) connected to the power system. This paper proposes simultaneous using both superconducting magnetic energy storage (SMES) and R-type solid-state fault current limiter (SSFCL) for enhancement the LVRT capability of WFs. The WFs is modeled with a doubly-fed induction generator (DFIG). The drive-train system is modeled by two-mass drive system. The analytical and simulation studies of using both SCES and R-type SSFCL for improving the LVRT capability of WFs are presented and compared with the impact of the Using the SMES alone. The simulation results show that simultaneous using both SCES and SSFCL effectively improves the LVRT capability of WFs connected to weak grids. Simulation were performed in PSCAD/EMTDC software environment.
