摘　　要：文章分析了逆变器间产生环流的原因,并提出了改进逆变器下垂控制策略的方式。通过引入虚拟阻抗,并在各逆变器间引入通信环节,该控制方式可以改善系统功率分布平衡,减小逆变器间输出电压的不同。应用MATLAB/simulink仿真证明了该控制方式的正确性和可行性。The reasons of circumfluence exist in the parallel inverter is analyzed in this paper and the way to improve the traditional droop control is also put forward. The control mode can improve uneven distribution of power and difference of output voltage in the original parallel system by introducing virtual impedance and adding the communication between the inverter system. Using MATLAB/simulink verify the correctness and feasibility of the control.

关 键 词：并联逆变器 下垂控制 虚拟阻抗
