Abstract :
Voltage sags (defined as short-duration reductions in the RMS voltage on one or more electrical phases) are becoming the most important power quality concern to electric utility customers with sensitive loads. They are characterized by their magnitude and duration (which is typically 0.5 to 30 cycles). Sags are predominantly caused by faults that are unavoidable on the distribution systems due to the interconnectivity of the utility systems. The distribution-class dynamic voltage restorer (DVR) is a series connected power electronics device which can compensate for distribution system sags and swells. By enhancing the voltage, the DVR can increase the availability of sensitive loads. A 2 MVA DVR was developed for the Electric Power Research Institute (EPRI) by Westinghouse
