摘要
基于自组织临界性及分形的思想,通过分析1981—2002年我国电网重大停电事故,揭示了我国电网停电事故的自组织临界性特征,并构建了全国电网及东北、华中和西北区域电网停电事故的标度-频度模型。通过研究如何用沙堆模型来描述电力系统的自组织临界性,提出了先建立各网省局等规模稍小电网的实时动态沙堆模型从而形成一个沙堆群的模型来模拟整个全国电网的设想。
Based on the concept of self-organized criticality （SOC） and fractal and by analyzing power system blackouts in China from 1981 to 2002, the characters of SOC of domestic power system blackouts are revealed, and the scale-frequency models for blackouts occurred in nationwide power grid as well as in Northeast China, Central China and Northwest China power grids are constructed. Through the research on how to describe the SOC of power system by use of sand pile model, a conception is proposed, that is, the real-time dynamic sand pile models for smaller regional or provincial power grids are established to form a sand pile group model by which the nationwide power grid can be simulated.
