摘要
本文提出一种快速确定多机电力系统暂态稳定域的方法.首先将多机系统等值简化,然后利用燕尾突变模型同时得到了暂态和静态稳定域,方便地找到了临界切除时间.理论分析和算例结果都表明,和其它方法相比,该方法在准确度和计算速度上都有明显的改善.
This paper proposes a method for fast transient stability assessment of large power systems.First themultimachine system is replaced by an equivalent circuit.Then transient stability region and steady statestability region are well defined by using swallowtail catastrophe.Critical clearing time is easily obtained.Theoretical analysis and results of a numerical example show its advantage in accuracy and computationspeed compared with other methods.
