The active compensation device (APF & SVG) is connected in parallel with the reactive power compensation component, making full use of the harmonic elimination function and efficient linear compensation function of the active compensation device to jointly undertake the tasks of reactive power compensation and harmonic control. This technology has fast and effective dynamic two-way reactive power compensation and efficient filtering functions for modern buildings such as wave-loaded industrial and commercial construction, hospitals, and data centers.。
