摘要： 当电网中个别发电机出现故障,不能为电网正常供电时,可能会引起其他发电机的超载级联,进而影响整个电网的正常有效运行。本文基于类Kuramoto模型,提出一种根据脆弱度切除负荷节点的发电机故障恢复策略,研究对比了切除脆弱度大的节点和切除脆弱度小的节点对系统恢复后网络性能的影响。研究表明,切除脆弱度小的节点后,剩余子系统的同步临界耦合强度Kc更小、所有节点频偏中的最大频偏绝对值更小、剩余子系统的负荷最小失同步扰动强度更大。因此,当电网中个别发电机出现故障时,利用本文方法能有效排除故障,使电网恢复稳定运行。

关键词: 类Kuramoto模型;脆弱度;网络性能;同步临界耦合强度;最小失同步扰动强度

Abstract: When a generator breaks down in the power grid, the fault generator can not provide power for the power grid, which may lead to cascading overload of other generators and affect the normal operation of the entire power grid. In this paper, the class Kuramoto model is applied to propose a stratege of power recovery by removing load nodes according to the degree of vulnerability, when a generator breaks down in the power grid. The study also compares the effects of removing the nodes with large degree of vulnerability and removing the nodes with small degree of vulnerability on the network performance. It is shown that when a node with small degree of vulnerability is removed, the critical coupling strength Kc of the remaining subsystems is smaller, the maximum absolute value of node frequency offset |Δw|max is smaller and the minimum load disturbance intensity ΔPmin of the remaining system is larger than those, when a node with large degree of vulnerability is removed. Therefore, when a generator breaks down in the power grid, in order to make the power grid restore to steady-state, using this method can effectively eliminate the fault.

Key words: class Kuramoto model, degree of vulnerability, network performance, critical coupling strength, minimum load disturbance intensity
