Research on Inverter Control Scheme With Current and Voltage Harmonics Comprehensive Suppression Function
摘要
Abstract
An improved controller design method for inverter’ s operating with extra function to suppress current harmonics or voltage harmonics was proposed. When at least two this-type inverter operating in micro-grid, they could collaboratively bear current harmonics and voltage harmonics suppression tasks respectively. This would benefit the micro-grid further wide application. Firstly, the principles of harmonics comprehensive suppression were analyzed. Then, combining with virtual output impedance design technology, droop control strategy, and proportional resonant (PR) control method, two kinds inverter controllers with different harmonics suppression purpose were designed. Finally, the effectiveness of the above control strategies was verified by MATLAB/Simulink simulation results. The total harmonic distortion ( THD) values of current and voltage were obviously reduced with higher power allocation accuracy when these two inverters parallel connected with the micro-grid.关键词
