摘　　要：直流区域配电网具有结构简单、可靠性高和线路损耗较小等优点,但其复杂的拓扑结构、多变的运行工况和结构的高度电力电子化等特点给其稳定运行带来了挑战。本文以船舶直流区域配电系统为研究对象,采用模块化建模方法,对船舶直流区域配电系统进行合理划分,基于多领域统一建模Modelica分区域建立了配电模型自下而上建立了直流变换电源模型、单相逆变电源模型、三相逆变电源模型等电力变换模型,构建了基于Modelica的某船舶直流区域配电系统模型。The DC regional distribution network has advantages such as simple structure,high reliability and small line loss.However,its stable operation is severely challenged by its complex topological structure,changeable operating conditions and highly power electronic structure.This paper takes the ship direct current electric distribution system as the research object,adopts the modularized modeling method to divide the system reasonably.Based on the multi-domain unified model Modelica,power conversion model of DC source converter,single-phase inverter,three-phase inverter are established regionally.A ship DC regional electric distribution system model based on Modelica is built as well.
