Introduction
SFR-SVG series static reactive power generation cabinet takes digital signal processor (DSP) as the core, parallels the self changing bridge circuit on the power grid through reactors, uses real-time data acquisition technology and dynamic tracking technology to detect the voltage and current information of the power grid, extracts the reactive component of the load current after internal DSP calculation, and then drives the PWM signal to IGBT, According to the reactive current, the three-level topology circuit is controlled to generate reactive current.
