摘　　要：针对全电力船舶电力网络的特点及日益突出的暂态稳定性问题,论文从某电力船舶的实际负荷情况和运行需求出发,设计并建立了该船的辐射形和环形两种电力网络拓扑,随后应用PSAT电力系统分析软件分别对这两种电网拓扑在投切大负荷和短路故障两个过程中的暂态稳定性进行了对比分析,仿真结果表明环形网络拓扑具有更强的在故障下左右舷配合供电的能力,故其暂态稳定性优于辐射形拓扑。Aiming at the characteristics of all-electric ship power network and the increasingly prominent transient stability problem,this paper designs and establishes the ship's radiative and ring power network topology from the actual load situation and operation demand of a power ship.The PSAT power system analysis software is used to compare the transient stability of the two grid topologies in the process of switching large load and short circuit fault.The simulation results show that the ring network topology has stronger under fault.The shipboard is equipped with the ability to supply power,so its transient stability is better than the radial to⁃pology.
