Abstract
A high voltage direct current (HVDC) instantaneous power monitoring system is provided. The high voltage direct current (HVDC) instantaneous power monitoring system includes a calculation processing unit receiving three-phase current and voltage, detecting a synchronous phase angle from received three-phase current and voltage, and transforming two-phase data into two-phase data to output two-phase data; and a data processing unit storing data transformed at the calculation processing unit.
