摘要
分析大扰动下一类电力系统暂态电压失稳机理.将薄弱负荷节点电压矢量作为该系统电压稳定性判断依据,给出薄弱负荷节点的确定方法.对IEEE-39节点系统仿真算例的分析证明了该方法的有效性.
The instability mechanism of a class of power system under large disturbance was studied. The voltage vectors of weak load node were used as transient voltage instability criteri- on, and the method for determining the weak load nodes was given. Simulation on IEEE - 39 nodes system shows the effec- tiveness o~ proposed method.
