摘　　要：航天器接口数据单记录了供配电系统中设备之间的参数和连接关系,是系统设计的载体和依据。针对供配电系统设计中模型重用难、扩展难、研发周期长的问题,基于航天器接口数据单和多领域统一建模语言Modelica对供配电系统映射建模与仿真问题展开研究。首先对接口数据单映射建模系统的基础组成与功能进行了分析,并依据层次化、结构化的思想,确定了Modelica通用模型库的组织形式。然后分析确定了航天器接口数据单与Modelica语言之间的相互映射关系,并给出了系统模型框架生成的实现算法。最后以实际工程案例为基础,对映射生成模型进行了仿真验证。结果表明,映射生成的供配电系统模型仿真结果正确。通过航天器接口数据单的映射建模方法,能够方便快速地对供配电系统展开仿真设计。The interface data sheet of a spacecraft records the parameters and connection relations between devices in the spacecraft power supply and distribution system,which is the carrier and basis of system design. In allusion to the problems of difficult model reuse and expansion,and long development cycle in design of the power supply and distribution system,the mapping modeling and simulation of power supply and distribution system is studied on the basis of spacecraft interface data sheet and multi-domain unified modeling language Modelica. The basic composition and functions of the interface data sheet mapping modeling system are analyzed,and the organization form of Modelica general model library is determined according to the idea of hierarchy and structurization. The mapping relationship between the spacecraft interface data sheet and Modelica language is analyzed and determined,and the realization algorithm of system model framework generation is given. On the basis of some actual engineering cases,simulation verification of the mapping generation model was performed. The result shows that the simulation results of the power supply and distribution system model generated by mapping are correct,and the simulation design of power supply and distribution system can be carried out conveniently and rapidly with the mapping modeling method of spacecraft interface data sheet.
