Analysis and Treatment of Voltage Sag of Sensitive Loads in Distribution Grid

针对供电线路电压暂降造成敏感负载运行中断的问题,基于固态切换开关、不间断电源、动态电压调节器等现有电压暂降治理措施的优劣分析与比对,提出了一种基于快速开关与双电源快速切换的电压暂降治理方案,并详细论述了其关键技术和工作原理,为电压暂降治理提供了新的思路。

Aiming at the problem of sensitive load operation interruption caused by voltage sag of power distribution lines,and based on the analysis and comparison of the advantages and disadvantages of existing voltage sag control measures such as solid-state switch,uninterruptible power supply,and dynamic voltage regulator,a voltage sag control scheme based on fast switching and dual-power-supply fast switching is proposed,and its key technologies and working principle are described in detail,which offers a new idea for voltage sag control.
