A novel topology of hybrid saturated core fault current limiter considering permanent magnets stability performance

In this paper, a novel hybrid saturated-core fault current limiter (HSFCL) is proposed considering the reliability of permanent magnets (PMs). For the HSFCL, a hybrid PMs/DC coil is designed to saturate the core and a fault limiting reactor is used to guarantee the fault clipping performance. The method of electromagnetic coupling is used to analyze the HSFCL based on ANSYS Maxwell. Simulation results have demonstrated that the HSFCL is efficient in fault clipping and stability enhancement of PMs.
