摘要
基于临界自组织理论,运用元胞自动机建立了电力系统脆性模型,并通过对6节点系统的脆性仿真,探讨了系统脆性激发的规律。结果表明,脆性发生时大都具有从临近线路向外蔓延的特点;脆性的发生和电力线路的负载状况有关;只有少部分元件能激发系统的脆性。
Based on the theory of self-organized criticality,a brittle model of electric power system was built with the cellular automata method. By simulation of 6 nodes system,the rule of brittleness motivation was discussed. Results show that the brittleness occurence has the characteristic of weedy from near fine to outer. The happening of brittleness is related to the load condition. Only some elements can lead to the cascading collapse.
