Novel dynamic TSC+SVG mixed reactive compensation device

The utility model discloses a novel dynamic TSC+SVG mixed reactive compensation device. The reactive compensation device comprises an SVG controller, an SVG power unit and a TSC branch. The SVG power unit comprises a breaker, a current sampling unit, a reactor and an IGBT module. A reactive value needed by a system is calculated by the SVG controller. By utilization of the characteristic of rapid SVG dynamic response speed, voltage fluctuation and change are inhibited in time. After the load is stabilized, the TSC branch is connected, and the reactive value emitted by SVG is reduced. After the load quits, by utilization of SVG dynamic response, the excess reactive value is absorbed rapidly, and the TSC branch is cut off gradually. The characteristic of rapid SVG dynamic response speed can be utilized to inhibit voltage fluctuation and change, as well as the defect of insufficient SVG capacity can be overcome, the SVG works in a light-load state, the service life of the SVG is prolonged, fine compensation can be carried out, voltage fluctuation can be inhibited and the flicking capability is raised greatly.
