Automatic compensation controller for reactive power

Overview

The reactive power automatic compensation controller uses a high-speed and high-performance microprocessor as the core device to simultaneously sample 3-phase voltage and 3-phase current signals, and provides 6 types of compensation schemes for split compensation and 10 types of co compensation schemes, as well as 12 switching coding schemes. Users can freely choose by modifying the control parameters. Once the control parameters are modified, they are permanently saved and will not be lost in case of power failure. The switching of the capacitor bank is controlled by the fundamental power factor niche wave reactive power composite control, which is stable without switching oscillation and insensitive to voltage harmonic current harmonic interference. Automatic control for reactive power compensation in AC power systems below 45Hz-65Hz and 0.4kV.
