Introduction
SFR-SVG is a static var generator. It is based on the digital signal processor (DSP), and the self-switching bridge circuit is connected in parallel to the power grid through the reactor. The real-time data acquisition technology and dynamic tracking technology are used to detect the voltage and current information of the power grid. After the internal DSP calculates, the reactive component of the load current is extracted, and then the PWM signal is sent to the internal IGBT to control the inverter to generate the reactive current that meets the requirement according to the setting, thereby achieving the purpose of reactive power compensation.
