New Coherency Identification Approach and Its Application to Generator Tripping Algorithm

  • 摘要: 为准确预测系统失稳模式,提出了基于系统失稳时刻状态矩阵分析的同调识别方法.通过对失稳时刻特征值及右特征值向量的分析,预测系统主导失稳模式,确定分群情况,并用扩展等面积法量化该系统的稳定裕度.通过分析稳定裕度对切机控制的灵敏度,得出最佳的切机控制策略.在改进的IEEE-39节点上对本文所提出的算法进行验证.结果表明,本文所提供的同调识别算法能较好地识别机组分群情况.经时域仿真试验可知,基于灵敏度的切机策略能抑制系统暂态失稳.
