动态电压恢复器(DVR)是目前补偿电压凹陷最为有效的装置。

Dynamic voltage Restorer (DVR) is considered as the most effective device to compensate the voltage sag.

通过对单机。动态负荷模型添加无功功率动态补偿装置，可以改变原系统的分岔点，增加了负荷极限，从而提高了系统电压稳定性。

Through the single-dynamic load model dynamic reactive power compensation device can change the original system bifurcation point, increase the load limits and improve the system voltage stability.
