Summary:In this paper a new algorithm based on tuned filters to extract the positive, negative and zero sequence instantaneous components of distorted and unbalanced electrical signals is shown. The new algorithm can be used in applications such as signal parameter estimation, power quality analysis and it can be useful for estimating the reference signal of some compensation devices used to improve the power quality. The algorithm performance is evaluated by simulations in Matlab/Simulink and through its implementation in real time on a dSPACE 1104 development board. In addition, the experimental setup results show an outstanding performance. [PUBLICATION ABSTRACT]
