Aiming at the power quality problem of voltage sag in distribution network, the control factors and effects of dynamic voltage restorer (DVR) and distribution static synchronous compensator (DSTATCOM) are studied to flexibly configure DFACTS devices and improve the voltage quality of distribution network. Firstly, the basic principle and compensation strategy of DVR and DSTATCOM are elaborated. Then, the performance influencing factors of two compensation devices are deduced. The influence of voltage sag amplitude, system capacity and load capacity is discussed. It is concluded that the voltage compensation performance of DVR is directly related to load capacity and voltage sag amplitude, while DSTATCOM is directly related to system capacity and voltage sag amplitude. Finally, the effectiveness of the proposed method is validated by comparing the control effects of the two compensation devices on voltage sag under different voltage sag magnitude, system capacity and load capacity, which provides a theoretical basis for the reasonable access of DVR and DSTATCOM in distribution network.
