中文摘要
随着对电气系统可靠性要求的提高,健康监测与故障检测至关重要。永磁电机中常见的匝间短路故障会导致严重损坏,需及时检测与缓解;而高阻连接故障虽不直接导致严重后果,但会引起相位不对称。本文提出一种基于零序电压的检测与分类方法,旨在提升电机系统的运行可靠性。
English Abstract
Health monitoring and fault detection are becoming more and more important in electrical machine systems due to the increasing demand for reliability. Winding turn fault is a common fault in permanent magnet (PM) machines, which can cause severe damages and requires prompt detection and mitigation. High resistance connection fault, which results in phase asymmetry may also occur but does not requi...
