Abstract
The active SFCL can too suppress rapid-circuit current caused with a three-phase grounded fault effectively, and also the power system’s safety and reliability could be improved. Furthermore, combined with the loss of the space between your fault location and also the SFCL’s installation position, the present-restricting performance increases. To be able to calculate the overvoltages caused within the other two phases, the symmetrical component method and sophisticated sequence systems may be used. It ought to be noticed that, for that distribution system with isolated neutral-point, the reactance ratio m is generally bigger than four. In consideration that applying superconducting fault current limiter can be an achievable solution, within this paper, the results of the current compensation type active SFCL in it are studied through theoretical derivation and simulation. The simulation results reveal that the active SFCL can enjoy an apparent role in restraining the fault current and overvoltage; also it can lead to staying away from damage around the relevant distribution equipment and enhance the systems safety and reliability. Throughout the study process, cellular the alterations within the locations from the DG units attached to the system, the DG units injection capacities and also the fault positions, the active SFCLs current-restricting and overvoltage suppressing characteristics are generally simulated in MATLAB
