Abstract

The authors address the problem of estimating the average power of electrical systems under nonsinusoidal conditions. Firstly, a time-domain based algorithm is proposed, which smooths sampled data using suitable coefficients, prior to their numerical integration. Then, the algorithm performance is quantified with respect to narrow- and wide-band noise and finally, simulation results are presented showing its effectiveness in estimating average power when starting from multifrequency voltage and current samples
