Influence of distributed generation systems in the distribution systems can increase the level of short-circuit current. The effectiveness of distributed generation systems is affected by the size, location, type of distributed generation systems technology, and the methods of connecting to distribution systems. Wind turbine system is the examples of distributed generation source. Not only does the using of fault current limiter reduce the pressure on network equipment, but also it can provide a connection to improve the function of the system. There are different types of superconducting fault current limiter, which are made of various superconducting materials and with different designs. Superconducting fault current limiter can be categorized as resistive, inductive and bridge. In this research, the effect of superconducting fault current limiter factors investigated on transient recovery voltage, voltage drop and transient behavior of wind turbine systems based on fixed speed wind turbines, in order to study the behavior of all three types of superconducting fault current limiter that was installed in distributed generation systems. The simulation results show that the transient recovery voltage, the voltage drop and the transient behavior of fixed speed wind turbines have been improved using superconducting fault current limiter
