The Static Var Generator (SVG) connects a voltage source converter in parallel with the grid through a filter. By controlling the amplitude and phase of the converter output voltage, it supplies exactly the inductive or capacitive reactive power the load needs, continuously and without steps. Transient response is under 50 µs and full response under 10 ms, so there is no over- or under-compensation, even with fast fluctuating loads such as welders, cranes, compressors and motor starts.
Compared with capacitor banks, the SVG has no switching transients, no risk of resonance with network harmonics and keeps its output at low voltage, helping sites keep a high power factor and avoid utility reactive energy penalties.
