摘要 本文在详细考虑直流系统模型的基础上,利用整个电力系统动能、势能和总能量的高阶Taylor级数展开式形成一种快速求取交直流联合电力系统临界切除时间的方法。该方法由于在模拟持续故障轨迹时,可采用较大步长,因而可大大减少总的选代次数,提高计算速度。实例分析表明,本文方法是准确的,可用于交直流联合电力系统暂态稳定性的快速分析。 Based on the detailed model of DC system,this paper presents a fast algorithm to calculate the criticalfault-clearing time of AC/DC power system using high order Taylor series expansion of kinetic energy, potential energy and total energy. Because longer steps can be used insimulation of the fault trajectory, the algorithm can minimize total number of iteration and computation time.Through the analysis of example, it is showed that themethod is accurate, and it can be used in fast analysis oftransient stability AC/DC power system.
