Instantaneous interference electricity compensation device

The invention provides an instantaneous interference electricity compensation device, which is arranged between a load and a power grid, and comprises an inductance module; the monitoring module is connected with the inductance module in parallel and is used for monitoring the voltage at the two ends of the inductance module; the control module is connected with the monitoring module in parallel; the capacitor module is connected with the control module in parallel, so that the inductor module and the capacitor module are connected to form a resonant circuit; two ends of the charging module are respectively connected with a first switch and a second switch; the first switch is arranged between the control module and the charging module; the second switch is arranged between the charging module and the capacitor module; when the voltage at the two ends of the inductance module changes, the control module switches the closed end points of the first switch and the second switch, and the charging module is connec
