| 摘 要： | 提出了一种基于ESAC(Energy Systems Analysis Consortium)标准的分布式电源系统稳定裕度监控方法,推导出当分布式电源系统不满足稳定裕度要求时,源级开关电源输出阻抗与负载级开关电源输入阻抗之间的约束关系。在此基础上,利用外加小信号电流扰动法实现了基于ESAC标准的分布式电源系统稳定裕度监控,并给出了具体实现电路。最后,以双Buck级联分布式电源系统为例,通过仿真证实了该监控方法的可行性与优越性。

| Abstract: | This paper introduces an approach to monitoring the stability margin of a distributed power system. Based on the ESAC (Energy Systems Analysis Consortium) criterion,the relationship between the output impedance of the source subsystem and the input impedance of the load subsystem is derived as the distributed power system has an unfavorable stability margin. Then,a small-signal perturbation current is injected into the DC bus. The stability margin monitoring based on the ESAC criterion can be completed by m... |
