Eddy-current loss of NdFeB permanent magnets (PMs) is widely analyzed in PM motors. This paper proposes a coupled 2-D transient finite-element analysis (FEA) of the saturated core fault current limiter (SCFCL) and 3-D analytical model of PMs to evaluate eddy-current loss in SCFCL. The comparison between the result from coupled method and that from 3-D FEA verifies the applicability of the coupled...
This digest proposed a model of superconducting controllable reactor and calculates its reactance based on finite element method. In order to ensure the safe operation of superconducting reactor, the digest devises a control system for superconducting windings based on S7-200 PLC after analyzing the DC component and overvoltage of superconducting winding and puts forward an optimal control strategy...
