摘　　要：基于自组织临界理论,以直流潮流为基础,建立了舰船电力系统连锁停电的OPA模型。通过OPA模型模拟了舰船电力系统发生连锁故障的过程并揭示出舰船电力系统发生大停电事故的本质;研究了线路可靠性和线路容量对系统停电分布的影响,结果表明,增强线路可靠性和提高线路容量有利于系统抵御连锁故障。此外,对比环形舰船电网结构和辐射型舰船电网结构的停电规模分布,从系统自组织临界特性的角度验证环形舰船电网结构可靠性更高。Based on self-organized criticality theory and DC power flow,the OPA model of cascading outage in ship power system is established.The OPA model is used to simulate the process of cascading failures in ship power system and reveal the es-sence of blackout in ship power system.The influence of line reliability and line capacity on outage distribution is studied.The re-sults show that enhancing line reliability and line capacity is beneficial to the system against cascading failures.In addition,com-pared with the outage scale distribution of the ring ship power grid structure and the radial ship power grid structure,it is verified that the ring ship power grid structure is more reliable from the perspective of self-organized criticality of the system.
