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

Abstract

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.
