摘要
在结构保持模型的基础上，根据网络中暂态能量的变化规律，定义了支路及割集的脆弱性指标。依赖于该指标值的排序，可以有效地识别出影响电力系统暂态稳定性的关键支路及关键割集，确定网络中的薄弱环节，避免了大量的割集搜索计算。对６机系统进行仿真，验证了所提方法的有效性。
Based on the structure preserving model, according to the variation of transient energy in power network, line vulnerability index and outset vulnerability index are defined. By the ordering of the indices values, critical line and critical outset influencing transient stability of power system can effectively be identified. and search and calculation of outset are simplified. The results of simulation on 6-generator power system verify the validation of the indices.
