Design of waveform generator for equipment sensitivity study during power quality events

This paper presents a new simulation method for pei$onning equipment sensitivity study during power quality events. Power quality wavefonn events such as voltage sags, swells, transients, etc. may cause sensitive loads to trip or mis-operate. For better coordination between the system and the equipment, it is necessary that the effects of specific events on the equipment behavior be thoroughly evaluated. This paper serves such a purpose. A library has been designed for generating various types of event waveforms. By imposing these Waveforms on the equipment and tuning various waveform features, the equipment behavior can be correlated to specijk event parameters. Methods and case studies as well as sof iare implementation issues in MA TLAB environment are illustrated.
