基于节点电压可靠性指标的系统薄弱点识别

Identification of the System Weak Bus Based on Voltage Stability

电网可靠性表征了电力系统的稳态与暂态的性能,将节点电压作为可靠性指标,研究电力系统静态电压稳定问题,采用了四种指标寻找系统薄弱点和薄弱区域,并与传统的模态分析法作对比,对可能成为薄弱节点的概率进行计算、筛选和排序,为电网运行检修人员提供直观信息。

Power grid reliability characterization of the power system steady state and transient performance,and the node voltage as reliability index,the power system static voltage stability problem,adopted a system of four indicators to find vulnerabilities and weak areas,and compared with the traditional modal analysis,probability calculation of may become weak nodes,filtering and sorting,provide visual information for power grid operation maintenance personnel.
