摘要:
针对电网中的连锁跳闸现象,提出一种针对潮流转移引发连锁跳闸的关键节点识别方法。根据连锁跳闸支路的表现形式和后备保护的动作方程,确定筛选支路受扰严重性的评价指标,筛选出严重受扰的支路。结合初始故障断开后系统中支路电流与节点注入功率之间的关系,利用聚类分析算法筛选电网中的关键节点,并对关键节点对电网安全运行水平的影响进行研究。以IEEE39节点系统为例进行仿真分析,结果表明,该方法筛选关键节点是有效的,可以为电网预防连锁跳闸提供帮助。
Abstract:
Aiming at the phenomenon of cascading trip in the power grid, a method for identifying the key nodes of the grid cascading trip caused by the power flow transfer was proposed. According to the manifestation of the cascading trip branch and the action equation of the backup protection, the evaluation index for screening the severity of the cascading disturbed branch was determined, and the severely disturbed branch was screened out. Combining the relationship between the branch current and the node injected power in the system after the initial fault disconnection, the cluster analysis algorithm was used to filter the key nodes in the power grid, study the impact of key nodes on the safe operation of the power grid. Taking the IEEE39-bus system as an example for simulation analysis, the analysis results show that the key node screening method proposed is effective and can provide help for the prevention of cascading trips in the power grid.
