Sensitivity of adjustable speed drive to voltage sags and solution

Abstract

This project was discuss a about sensitivity of adjustable speed drive to voltage sags and solution. This project is presence the three phase (balance or symmetrical) and single phase ASD and the result from the experimental was been plotted as tolerance curve and by the analysis tripped was happen when voltage sags occur in the system and might be damage to the equipment. The interruption happened less than 1 second in half cycle. This project also discusses the suitable method such as UPS mitigation of voltage sags, mitigation device was be installed at the system load interface for power quality enhancement are presented.
