Research on control strategy of dynamic voltage restorer
The voltage sag is one of the most serious power quality problems, especially for the sensitive power user. At present, dynamic voltage restorer (DVR) is the effective solution to suppress the voltage sag. And the control strategy of DVR determines its dynamic performance. In this paper, a new control strategy, closed-loop control integrated with feedforward adjustment based on interference voltage, is proposed to resolve current defects of DVR control system. The new control strategy not only improve steady margin but also speed up system dynamic response. The better performance of advanced control strategy is then validated by simulation studies.
