Static Var Generator
magnitude and phase of inverter AC voltage, so as to achieve the purpose of reactive power compensation and 3 phase load balancing .
Because the switching frequency of IGBT is very high (up to 25.6kHz), SVG can compensate rapid reactive loads and achieve quite high
compensation accuracy. SVG is the best product in the field of reactive power control.
Static Var Generator detects load current in real time through internal and external CT and analyzes the reactive current of load by TI DSP and FPGA,
then generates PWM signal to IGBT inverter(3 Level) to generate inductive or capacitive current and compensate reactive current to realize the target power factor.
SVG can also compensate phase imbalance. Compared with the traditional capacitor bank, SVG has the advantages of fast response and high compensation accuracy
without under-compensation or over-compensation problems, avoid resonance,etc.

APPLICATIONS:
Oil drilling industry leads to a large number of reactive power consumption, resulting in poor stability of the power system.
AC-DC conversion during the operation of DC electric drive drilling rig will produce a large amount of harmonic wave components,
