Abstract Based on the actual investigation in Xiamen Xiang’an district, the causes and effects of voltage sags in this area are analyzed from the perspective of power grid side and user side respectively. On this basis, a comprehensive prevention and control scheme is proposed, which is coordinated with power grid side reconstruction and user side management. The application of fast switching technology in switching power supply is emphasized on the power grid side. On the user side, the measures of setting the action delay of low voltage release reasonably and cooperating with voltage compensation equipment are put forward. The proposed scheme can effectively alleviate the influence of voltage sag on important loads.
