EFFECTS OF FCL ON WIND TURBINES EQUIPPED WITH DFIGS DURING GRID FAULTS

Nowadays, the power systems are faced to new challenges by increasing use of renewable energy sources penetration. The main drawback of wind turbines that equipped with Doubly Fed Induction Generators (DFIGs) is the grid faults or low voltage ride through capability. In this paper, a new solution for uninterrupted operation of the wind turbine driving a DFIG has been proposed during the grid fault. A fault current limiter (FCL) is placed in series with the rotor circuit to confining the rotor over current during grid fault. Also, a Static Synchronous Compensator (STATCOM) has been applied for providing required reactive power in faults and steady states. Capability and modeling accuracy of the proposed method is confirmed with simulating a sample power system with PSCAD/EMTDC software.
