摘　　要：电力系统大停电具有自组织临界特性,电力系统过载或过负荷同样具有基于自组织临界理论中的协同学原理所揭示的规律。提出了一种能够形象地说明协同学原理的沙堆模型,设计出了沙堆模型的程序流程图,编写出了沙堆模型程序,并且设定了沙堆模型算例。通过总结不同算例的计算结果,分析了沙粒的分布特性。计算结果表明沙堆模型能够很好地模拟协同学原理所揭示的规律,为今后进一步利用沙堆模型,研究其在电力系统中的应用提供理论基础。The power system blackout has the self-organized critical characteristics,and the power system overload has the same features as revealed by the synergetic theory which is based on the self-organized critical theory.A sand pile model is proposed in this paper that can vividly describe the synergetic theory.The corresponding program flow chart and programs are developed and the computation examples are provided.The distribution characteristics of sand particles are obtained by analyzing the calculation results of different computation examples.It is proved through computation that the sand pile model can well simulate the rules revealed by the synergetic theory.The computation results can provides a basis for further application of sand pile model in power system.
