Fault ride-through (FRT) is required for wind turbines connected to the grid, which is steadily increasing in recent years. This paper presents a solution for wind energy conversion system based on use series braking resistor (BR) and STATCOM simultaneously for improving FRT. The wind energy conversion system (WECS) is considered as a fixed-speed system, equipped with a squirrel-cage induction generator. The drive-train is represented by two-mass model. The analytical and simulation studies of the BR and STATCOM for improving FRT capability are presented and compared with the impact of only the application of the STATCOM. The simulation results show that simultaneously STATCOM and BR effectively improve the FRT capability of WECS compare to STATCOM. PSCAD/EMTDC software is used for simulation.
