摘要
众多复杂系统在临界相变的临界点附近存在临界慢化现象。针对目前大多数理论确定电力系统自组织临界点的算法复杂、计算时间长或无法提供实际应用中最为关心的判别"阈值"信息的现状,将临界慢化理论用于确定电力系统自组织临界点,并基于Mann-Kendall检验方法确定自组织临界影响因素的临界阈值,方法简单、易于实现。CEPRI 36节点系统和甘肃酒泉实例系统的仿真分析结果与滑动T-检验、负荷损失柱状图、幂律尾分布K-S检验证明了以上计算方法的正确性和高效性,从而可为实时预防电力系统大停电并提前做出针对性的预防控制提供理论基础和技术依据。
The phenomenon of critical slowing down near the critical point of critical phase transformation was common in many complex systems. Currently the algorithms to get the power system’s self-organized critical point was complicated or could not compute the critical value of related factors, which was concerned most in the application. Therefore critical slowing down theory was applied to seek the selforganized critical point in this article. And further Mann-Kendall test was used to compute the critical value of power system’s self-organized critical factors. This method is easy to implement and verified available and efficiency on CEPRI 36 bus system and Jiuquan area in Gansu power grid by simulating and K-S test, slide T-test. And this method can provide theoretical and technical basis for the prevention and control of large-scale blackouts.
