基于xy子空间负序高频电流残差的对称六相永磁同步电机匝间故障严重程度监测

This article proposes a fault severity monitoring method for interturn short-circuit fault (ISCF) based on the xy subspace negative-sequence high-frequency (HF) current residuals in symmetrical six-phase permanent magnet synchronous machines. For six-phase machines, both the fundamental frequency and HF behaviors in the xy subspace can be used to design fault indicators. However, another fault typ...
