摘要
分析了采用下垂控制方法时并联运行的逆变器不能实现功率均分的原因,对此提出一种新的改进策略,通过设计自适应的虚拟阻抗来实现逆变器合并阻抗达到匹配,并使逆变器的合并阻抗满足功率均分和抑制环流的重要条件,并采用小信号模型分析法进行稳定性分析和参数优化。利用MATLAB/Simulink对所提方法进行了仿真验证,表明方法在理论上的正确性,具有一定的工程可行性。
The reasons why inverters running in parallel cannot achieve power equalization when using droop control method is analyzed,and proposes a new improvement strategy to achieve inverter combined impedance matching by designing adaptive virtual impedance,so that the combined impedance of the inverter meets the important conditions of power equalization and loop current suppression,and the small-signal model analysis method is used for stability analysis and parameter optimization.MATLAB/Simulink is used to simulate and verify the proposed method,which shows that the method is theoretically correct and has certain engineering feasibility.
