Note:
1. Capacity (Mvar) refers to the rated regulation capacity within the dynamic regulation range from inductive reactive power to capacitive reactive power.
2. The air core reactor is used for the equipment, and there is no cabinet, so the placement space needs to be planned separately.
3. The above dimensions are for reference only. The company reserves the right to upgrade and improve the products. The product dimensions are subject to change without notice.
Power compensation device, with multi-chip DSP+FPGA as the control core, adopts instantaneous reactive power theory control technology, FFT fast harmonic calculation technology, and high-power IGBT drive technology. The design goal is to achieve high reliability, easy operation and high performance. The product can provide capacitive or inductive reactive power quickly and continuously, realizing various control modes such as constant assessment point reactive power, constant assessment point voltage and constant assessment point power factor, as well as comprehensive compensation. FGSVG series high-voltage dynamic reactive power compensation device can not only automatically compensate reactive power, but also dynamically compensate harmonics at the same time to ensure stable operation of the power system.
