A simplified state-of-the-art sample shifting technique for microcontroller based single phase power measurement

A unique state-of-the art sample shifting technique (SST), proposed in recent literature, is utilized particularly for the estimation of reactive power from sample values of voltage and current signals only while the active power is evaluated from their as usual product. Also all other related parameters, as described in the IEEE 1459-2010 standard, are estimated in this measurement. A hardware prototype is developed to study its viability by estimating the measurement errors under pure and different polluted environment conditions.
