Thereby, fault currents can be distinguished from the inrushes if the improved correlation coefficient between the pre-half and the post-half cycle of the measurand is larger than the setting value.Test results show that all types of internal faults even accompanied by magnetizing inrush can be correctly identified from the inrush with the proposed algorithm. Besides with high reliability , this scheme has satisfying sensitivity.

文章解决了对半自动桥式抓斗卸船机运行状况的监测问题，可以及时发现、预告故障，避免重大事故的发生和巨大的经济损失，而且可以根据卸船机的运行状态找出生产系统中的事故隐患，消除事故隐患，减少由于人为和技术因素引起的故障停机时间。

The thyristor and stator winding have different topology architecture when the inductionmotor is controlled by the thyristor. Based on the fault characteristics of the inductionmotor, the current through the thyristor and the stator winding are studied when theshort-circuit or open-phase fault is occurred. The reasonable protection method based onthe different topology architecture is given in the thesis, and the induction motor and theover-current of the thyristor are reliably protected.
