摘要
针对传统下垂特性控制存在的不足,提出基于下垂特性的改进并联控制方案。改进方案在传统下垂特性控制的基础上增加电压频率、幅值修正环,提高了逆变器并联工作性能,削弱了连线阻抗等电气参数对逆变器的影响。最后在Matlab/Simulink仿真平台对该方案进行仿真实验,结果验证了改进方案的良好性能。
According the disadvantages of traditional droop characteristic control, an improved scheme of parallel control based on droop characteristic is proposed. The voltage frequency and amplitude correction loop are added to the traditional droop characteristic control. The performance of parallel of inverter is improved and the impact of wiring and other electrical impedance parameters on inverter is decreased. The simulation is implemented under Matlab/Simulink platform, results show the improved scheme have good performance.
