NC SPC detects load current through an external current transducer (CT) and analyzes the reactive component of load current by the DSP controller. Then it controls the IGBT inverter to generate reactive current and compensate load reactive current to meet the target of line power factor.
NC SPC detects the load current through an external current transducer (CT), analyzes whether the system is balanced or not, and also calculates the required SPC current, and sends the signal to the IGBT. Then the unbalanced current is transferred from the high-current phase to the low-current phase. Finally, the three-phase current is balanced at the source site.
The NC SPC samples the voltage at the compensation point and sends the voltage signal to the DSP controller for comparison with the set value. When the voltage exceeds the Umax value, the NC SPC generates an inductive current to reduce the voltage. When the voltage is below the Umin value, the NC SPC outputs capacitive current to increase the voltage. Finally, the NC SPC stabilizes the voltage in the normal range.
