Resumen:
This paper presents a globally convergent nonlinear observer to achieve grid synchronization with a three phase pure sinu- soidal unbalanced grid. The proposed algo- rithm allows to extract the positive and neg- ative sequence components of the grid volt- age. Since it is frequency adaptive, it is inmune to grid frequency variations. Another feature is that, since it is a reduced order observer, only three states are needed to implement it. The validity of the proposed scheme is verified through mathematical analysis and simulation results
