Investigation on the Dynamic Characteristics of PMFCLs for Large Capacity Applications

Abstract:

Permanent-Magnet-Biased Saturation Based Fault Current Limiter (PMFCL) is a preferable solution to suppress the fault current, and may find early applications in large capacity power systems due to prominent advantages. Firstly, the topologies and the operating principles of the PMFCLs are elucidated in this paper. Then a new concept namely effective magnetic flux density is proposed in order to describe the overall impacts of the magnetic field on the current limiting capacity of the PMFCLs. Lastly, theoretical analysis and mathematical simulation on the dynamic characteristics of different modes of PMFCLs are carried out comparatively. All the results present invaluable fundamentals for further study on the operating mechanism of different modes of PMFCLs as well as optimization of the fault current limiting topology design.
