| 摘要: |
| 为了减小电网连锁故障发生的频率及规模，考虑初始故障后元件及电网运行状态的变化和故障传递程度，结合模糊理论和元胞自动机理论构造基于模糊元胞自动机的电网故障模型，并基于潮流传输原理提出连锁故障演化过程中减少停电事故的切负荷控制规则和无功补偿控制规则，进而确定控制策略使用的时间、位置及调整量。基于IEEE 39节点系统进行停电事故仿真，仿真结果显示，采用控制策略后，电网承受100次故障的天数由4 300 d增加到7 000 d，同时一定次数的电网事故中产生较大损失负荷的故障次数明显减少，提高了电网的稳定性。 |

| Abstract: |
| In order to reduce the occurrence frequency and scale of grid cascading failure，a grid failure model based on fuzzy theory and CA（Cellular Automata） theory is constructed，which considers the operating condition change of elements and power grid after the initial failure，as well as the failure spreading degree. The control rules for load shedding and reactive power compensation during the failure evolution are proposed based on the power flow transmission principle to alleviate the power outage and the control strategy，including time，location and adjustment amount，is determined. A power outage of IEEE 39-bus system is simulated and results show that，with the proposed control strategy，the failure occurrence frequency is decreased from 100 times per 4 300 days to 100 times per 7 000 days while the times of failure resulting in larger load loss per a certain number of power failures is obviously reduced，which enhances the grid stability. |
