Research on Harmonic Extraction and Suppression Methods for Aviation Wide-Range Variable Frequency Power Supply Systems
摘要
Abstract
More electric aircraft(MEA)replaces the hydraulic and pneumatic systems on traditional aircraft with electric power systems.It has the advantages of small size,light weight and high reliability,and has attracted widespread attention in the aviation industry today.With the increase of nonlinear electronic devices in the MEA AC power supply system,they will generate harmonics to pollute the power grid,causing grid voltage distortion and affecting the power quality of the aviation power grid.Therefore,in the aviation AC variable frequency power supply system accompanied by harmonic interference,it is of great significance to accurately estimate the grid voltage information and further accurately extract and suppress the grid harmonics,which is of great significance to the power quality of the aviation wide-range variable frequency power supply system and the reliability of the electrical system.The frequency adaptive feedback link is combined with the cascaded dual second-order generalized integrator phase-locked loop(MDSOGI-PLL)method with good performance in harmonic extraction under the power frequency power grid.An adaptive cascaded dual second-order generalized integrator phase-locked loop(AMDSOGI-PLL)method is designed.This method can accurately track the frequency and positive and negative sequence components when accompanied by harmonics in the aviation wide-range variable frequency power supply system,accurately extract the positive and negative sequence components of each harmonic,and has a good harmonic suppression effect.Experimental results verify the accuracy of the proposed method.It can be concluded that this study improves the accuracy of estimating the state information of the power grid and improves the stability and reliability of electric energy when there are harmonics in the power grid.关键词
