Implementation of the IEEE Std 1459-2010 using Kalman filter for fundamental and harmonics detection

This paper presents an approach for the harmonic decomposition of voltage and current. This approach uses the Kalman filter combined with a frequency detection algorithm. It is applied to solving the power computations described in IEEE Std 1459-2010. The implementation of the filter is described and a comparison with the Fast Fourier Transform (FFT) is also provided. The paper also presents the results obtained using a free software developed using the QT framework which implements the power computations in accordance with IEEE Std 1459-2010.
