Power quality optimization is a new generation of dynamic voltage regulator. It connects voltage source inverters in series with compensating transformers in the power grid, which is equivalent to a variable voltage source. By adjusting the amplitude and phase of the output voltage of the inverters on the AC side, it can quickly absorb or emit the required compensation voltage, and realize the purpose of fast dynamic voltage regulation of the power grid. The device is a dynamic voltage regulator with IGBT/IGCT as its core. It is one of the main devices of Flexible AC Transmission System (FACTS). It represents a new direction of power quality optimization technology development in power system at present. The dynamic compensation device can quickly and continuously provide voltage source with phase angle and amplitude decoupling regulation, realize voltage and reactive power control, and ensure stable, efficient and high quality operation of power system.
