This paper develops a survivability-based protection for three phase induction motor drive (3 phi IMDs) systems against severe dynamic events. The developed protection is based on defining a survivability index GIMD, which is formulated in terms of the change in power created by a dynamic event experienced by a 3 phi IMD. The determination of GIMD provides an accurate tool to detect, identify, and respond to unsurvivable dynamic events. The efficacy and validity of the survivability-based protection for 3 phi IMDs are verified through simulation and experimental tests. These tests are conducted for 10hp 3 phi IMD under various types of dynamic events. Test results demonstrate the effectiveness of the survivability-based protection in responding to unsurvivable dynamic events to prevent damage to different components in a 3 phi IMD.
