Measurement of Active Power by Time Domain Digital Signal Processing

Popis výsledku v původním jazyce

The paper compares DSP time domain algorithms of one-phase active power measurement by non-coherent sampling that overcome some frequency-domain algorithms in active power estimation of non-sinusoidal signals. Measurement bias, uncertainty and sampling time necessary for required accuracy is compared for various data windows by simulations and measurements. Both monofrequency and multifrequency signals are dealt with. Analytical formulae for active power bias for rectangular and general cosine windows and for standard uncertainty of active power measurement are presented. A simple method of multiplexing delay correction for power measurement using multiplexing DAQ boards is described. The information from the paper can be used also for energy consumption and three-phase power measurement.
