摘要 为解决直流微电网中线路阻抗对传统下垂控制造成的影响,基于直流微电网系统结构特点,提出了一种主动阻抗检测方法,即通过主动注入单脉冲扰动,检测变换器输出电压、电流变化,获得线路阻抗信息,进而对下垂系数进行补偿,最终改善负荷分配精度和母线电压电能质量。由于该方法属于主动测量法,因此对电能质量影响微小并可控。最后通过仿真和实验结果验证了所提方法的可行性和有效性。 In DC microgrid, the existence of line impedance on the parallel converter output side results in bad influence on the traditional droop control method. To solve this problem, this paper propose an active impedance detection method based on the DC microgrid specific system structure. By injecting a pulse disturbance actively and detecting the changes of output voltage and current, the line impedance could be obtained and used to compensate the droop coefficient. This method improves the load current sharing accuracy and restores the dc bus voltage. Because the method belongs to the active impedance identification, the influence on power quality is tiny and controllable. Finally, simulation and experimental results validate the feasibility and effectiveness of the proposed method.
