Abstract

In this paper, the authors address the problem of estimating the average power of electrical systems under nonsinusoidal conditions. At first, a time-domain-based algorithm is proposed, which smoothes sampled data using suitable coefficients, prior to their numerical integration. Then, the algorithm accuracy is quantified with respect to wide-band noise. Last, simulation and experimental results are presented showing its effectiveness in estimating average power when starting from multifrequency voltage and current samples
