| 摘 要： | 该文建立了船舶电力系统的自组织临界性脆性模型,对船舶电力系统进行脆性分析,通过考察潮流动态来研究脆性发生的机理。该模型分为快动态过程和慢动态过程,前者为基于改进的直流潮流模型的船舶电力系统脆性模型算法,后者为船舶电力系统节点负荷和线路容量增长算法。仿真结果表明,船舶电力系统的脆性故障规模与发生次数在曲线的尾部都具有幂律特性,船舶电力系统脆性具有自组织临界性;同时,过载参数会影响船舶电力系统脆性的自组织临界性。

| Abstract: | A brittleness model with self-organized criticality is constructed in this paper to analyze the brittleness of ship power system.The model consists of two parts,reflecting fast action process and slow action process respectively,where the former is brittleness algorithm based on an improved DC power flow model,the latter is growing algorithm of node load and line capacity.Simulation results indicate that the failure scale and the variation of frequency of brittleness has power law characteristics at the tai... |
