Abstract: A fault-tolerant permanent-magnet vernier (FT-PMV) machine incorporates the merits of high fault-tolerant capability and high torque density. In this paper, a new remedial control is proposed for a five-phase FT-PMV machine with short-circuit fault of stator windings. Based on the principle of copper loss minimization, the aims of the proposed control strategy are to keep magnetic mot...

In this paper, a new very fast fault simulation method to handle the X-fault model is proposed. The method is based on a two-phase procedure. In the first phase, a parallel exact critical path fault tracing is used to determine all the detected stuck-at faults in the circuit, and in the second phase a postprocess is launched which will determine the detectability of X-faults. Keywords-digital c...

Even though shunt compensation of transmission lines (TLs) is a common practice to limit the overvoltages stemming from Ferranti effect, it may cause transient and steady-state resonant when one phase left open due single-pole-open condition following temporary phase-to-ground (Ph-g) fault. Furthermore, existing reactors potentially increase duration secondary arc current at fault point hence p...

Both torque ripple and current harmonics are enlarged due to single-phase open-circuit fault of five-phase permanent magnet synchronous motor (FPMSM). Based on chaotic-particle swarm, an adaptive optimization tolerant control algorithm is proposed for the FPMSM current. First, Park Clarke matrices modified in coordinate transformation process. A reduced-order decoupling matrix obtained under st...
