FEM Simulations of Permanent-Magnet-Biased Saturation Based Fault Current Limiter

Abstract:

The fault current limit technology based on the principle of permanent-magnet-biased saturation has several outstanding advantages in both economy and technology. A modeling method of PMFCL based on the finite element analysis platform – Maxwell is presented in this paper. The current limiting mechanism of line-type PMFCL is analyzed, on the basis of which the 2D and 3D models are established in Maxwell, and the corresponding experiments are designed as well. Comparisons between the simulation and experimental results indicate that the modeling method is reasonable. Research achievements of this paper provides theoretical basis for further studies of PMFCL.
