Static Var Generator Cabinet

Static var generator cabinet takes DSP as the core, connects the self-changing bridge circuit in parallel with the power grid through the reactor, adopts the real-time data acquisition technology and dynamic tracking technology to detect the grid voltage and current information, and calculates the grid voltage and current through the internal DSP calculation. After that, the reactive power component of the load current is extracted, and then the PWM signal is driven to drive the IGBT, and the three-level topology circuit is controlled according to the reactive current to generate a reactive current that meets the requirements, so as to achieve the purpose of reactive power compensation.
