Implementation of SFCL in DFIG Based Wind Energy System and its application

Now-a-days, due to the integration of wind network is existing grid the fault current levels are increasing day-by-day. The SFCL is the most probable device to rapidly limit the fault current and also provides reliable operation to the system under the fault condition. Due to this, it enhances protection device capacity also overall system stability and reliability. A resistive type SFCL is used for DFIG based WES for limiting the fault current is proposed. Basically, analyze and performance of designed SFCL by applying in a simple 3-φ transmission line system. The simulated SFCL model is implemented in a DFIG Based Wind Energy System, a 3-φ to ground fault current limiting scenario is explored for wind farm based network, a 10 MVA capacity of wind farm used for simulation purpose.
