Low voltage SVG
The low-voltage dynamic reactive compensation and harmonic control device (hereinafter referred to as SVG) independently developed by WindSun adopts intelligent algorithm for control, which can compensate reactive power, filter out harmonics, inhibit voltage fluctuation and flicker quickly, inhibit three-phase imbalance effectively, and can solve the power quality problems existing in the power supply system well.
Working principle: the basic principle of FGSVG series products is to form a self-commutation bridge circuit by using the power electronic devices (IGBT) that can be turned off, and the self-commutation bridge circuit is connected to the power grid in parallel through a transformer or a reactor. The amplitude and phase of the output voltage at the AC side of the bridge circuit can be appropriately adjusted, or the current at the AC side of the bridge circuit can be directly controlled, so that the circuit can absorb or emit reactive current that meets the requirements, and then the purpose of dynamic reactive compensation is realized.
