Resumo
This article presents the theoretical development and implementation
of an adaptive algorithm for real-time measurement
of electrical powers under sinusoidal, non-sinusoidal, balanced, and
unbalanced conditions according to the definitions given by IEEE
Standard 1459-2010. The algorithm is based on adaptive filter notch
filter implementation, where the parameters are adjusted by tracking
the amplitude and phase variations to improve the accuracy of the
power measurement. The algorithm uses the filter coefficients to calculate
powers, resulting in low computational burden. The results of
computer simulation and practical implementation using a fixed-point
digital signal controller are shown in detail, proving the accuracy and
efficiency of the algorithm.
