To reduce the size and requirement of DC biasing capacity of saturated-core fault current limiter, a novel hybrid compact saturated-core fault current limiter (HCFCL) is proposed by this paper. The three-limb structure with Permanent magnets can reduce the size and DC biasing capacity. Firstly, the principle of HCFCL is introduced. To validate the performance, various FEA simulations with the 3D nonlinear...
Eddy current loss of NdFeB permanent magnets (PMs) are widely analyzed in permanent magnet motors. And it's necessary to analyze this issue in saturated core fault current limiter (SCFCL). This digest discusses the coupled 2-D finite element analysis (FEA) of the SCFCL and 3-D analytical model of PMs to evaluate the eddy current loss of PMs in a SCFCL. The comparison between result from coupled method...
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...
The fault current limiter (FCL) is one of the most useful measures for limiting fault currents in power systems. This paper introduces a new structure for a parallel-type permanent magnet (PM)-biased saturation-based FCL (PPFCL). The PPFCL consists of two magnetic devices connected in parallel and in magnetic counter opposite to each other. The operating principle and the core inductances in different...
