Abstract
In view of the traditional phase locked loop fundamental phase tracking failure,the response speed of multi-SOGI phase locked loop is slow,and there is a big error caused by unbalanced voltage and harmonic components in the power system,a double-layer control (hormonal control)strategy was proposed based on the multi-SOGI.Simulation analysis was carried out under the condition of unbalanced voltage and harmonic,the results show that the proposed scheme is better than the traditional phase-locked loop and the multi-SOGI phase-locked loop to track the phase of the fundamental wave voltage of the grid.At the same time,it can effectively extract the amplitude of positive and negative sequence,and improve the fast,stability and efficiency of grid connected generation system.关键词
