Abstract :
In this paper, the performance of three harmonic detection methods is evaluated in term of precision, speed of convergence and calculation complexity. The algorithms are respectively based on the recursive discrete Fourier transform (RDFT), Kalman filtering approach and the instantaneous reactive power theory. Results obtained by simulations with Matlab-Simulink and their real-time validation with dSPACE are presented to compare the detection methods. The effectiveness of the algorithms is demonstrated in their application to the control of a hybrid active filter dedicated to harmonic resonance damping in industrial power systems.
