The power distribution system with distributed generation (DG) units, its fault current and overvoltage under disturbance conditions ought to be taken into account. In consideration that applying superconducting fault current limiter (SFCL) may be a feasible arrangement, in this paper, the impacts of a voltage compensation typr active SFCL on them are contemplated through theoretical derivation and simulation. The active SFCL is made out of an air-core superconducting transformer and a PWM converter. The magnetic field in the air-core can be controlled by adjusting the converters output current, and then the active SFCLs equivalent impedance can be regulated for current limitation and conceivable over voltage concealment. During the examination procedure, in perspective of the changes in the locations of the DG units associated with the framework, the DG units injection capacities and the fault positions, the active SFCLs current-limiting and over voltage suppressing characteristics are both simulated in MATLAB. The simulation comes about demonstrate that the active SFCL can play an undeniable part in restraining the fault current and overvoltage, and it can add to avoiding damage on the relevant distribution system with distributed generation and enhance the systems safety and reliability.
