| Abstract: | With the use of a large number of sensitive power loads in power system, voltage sags become power quality problems which people mostly pay attention to, and it has seriously affected the normal operation of equipment. When distribution system voltage drops,dynamic voltage restorer(DVR) can maintain the sensitive load side voltage stability. The circuit structure of DVR and its basic working principle to improve the voltage sags were given,dynamic characteristics of DVR also were discussed in detail, and a number of measures based on these characteristics to improve the performance were made. |
