摘　　要：潮流计算关系着电力系统的设计规划和稳定运行。为了分析直流区域配电系统的稳定性,本文在陆网潮流计算的基础上,针对直流区域配电系统的特点,确定了逆变器下垂控制策略。分析了电流均分的机理,使配电网络系统实现功率分配。完成了系统的潮流计算,通过仿真验证了该方法的有效性,降低了复杂工况对舰船配电系统的影响,有利于系统的安全稳定运行。The power flow calculation ＆ of vital importance to the design planning and steady operation of the power system. In order to analyze the stability of the DC-zonal power distribution system, according to the properties of the DC-zonal power distribution system, droop control strategy of the inverter＇s is confirmed based on the power flow calculation of land grid. The mechanism of current sharing is analyzed and the power distribution is achieved for the distribution network system efficiently. The power flow calculation of the system is finished, and the feasibility of the method is verified by simulation. The results show that method can reduce the influence that the complex operation on the shipboard distribution system which is conducive to the stable operation of the system.
