Description

Technical Field

[0001] The utility model relates to the technical field of filter compensation devices, in particular to a dynamic reactive power filter compensation device. Background Art

[0002] The dynamic reactive power filtering and compensation device is a device used in power systems to improve the power factor and voltage quality in the power grid system, reduce reactive power flow and oscillation problems in the power grid, and achieve dynamic regulation and filtering of reactive power by monitoring the power factor and voltage fluctuations in the power grid and compensating as needed to ensure stable operation of the power grid.

[0003] However, it still has the following disadvantages in actual use:
