摘　　要：飞机和船舶中的独立供电系统具有多等级电网混合交联、多元电气设备动态加载的特点,由此造成其传导干扰多源、多径传输,传导干扰分析和抑制面临极大困难。该文提出采用黑箱建模方法,仅基于设备端口特性参数的测量,通过戴维南等效建立传导干扰的多端口网络模型,进而可通过模型的级联构建系统级传导干扰分析模型。该方法无需设备内部电路参数和配置信息,模型通用性强。通过24 V直流供电系统验证,实验结果表明,随着系统用电设备数量和种类的增加,该方法仍能准确预测系统的传导发射情况,证明了该方法是系统级传导干扰分析的有效手段。The independent power supply systems in aircraft and ships have the characteristics of multi-level grid hybrid interconnection and dynamic loading of multiple electrical equipment,which result in multiple-source and multi-path transmission of conducted interference,and face great challenges in conducted interference analysis and suppression.This article proposes a black-box modeling method,which only measures the characteristic parameters of equipment ports,and establishes a multi-port network model of conducted interference through Thevenin equivalent.Then,a system-level conducted interference analysis model can be constructed through the cascading of models.This method does not require internal circuit parameters and configuration information of the equipment,and has strong generality.The effectiveness of this method is verified by a 24 V DC power supply system.The experimental results show that with the increase of the number and types of electrical equipment in the system,the proposed method can still accurately predict the conducted emission.It proves that this method is an effective means for system-level conducted interference analysis.
