PROJECT TITLE :

The Extended Newton-Phaselet Method for Determining the Reactive Power From the Active Power in Single-Phase Systems

ABSTRACT:

This paper presents the performance evaluation of the extended Newton-phaselet technique for determining the reactive power using only the active power in single-phase systems. The presented technique is structured to use one worth of the active power P to calculate one value of the apparent power |S̅|, whereas it employs six phaselet frames to calculate a worth of the angle θ (the section of S̅). Calculated |S̅| and θ are used to determine a value of the active power COMPUTER, which is compared to P in order to regulate |S̅| for the next Newton iteration. Furthermore, calculated values of COMPUTER, |S̅|, and θ at every iteration are employed to see a worth of the reactive power QC at that iteration. The extended Newton-phaselet method is implemented for performance evaluation using the measured active power equipped to different 1φ hundreds. Performance results of the developed method demonstrate easy implementation and high accuracy with minor sensitivity to load types or power factor standing (lagging or leading).
