摘　　要：势能边界面PEBS(PotentialEnergyBoundarySurface)法是暂态能量函数法的一种,将Taylor级数法暂态稳定计算的动态步长控制应用到PEBS法中,可以大步长的模拟持续故障轨迹,减小模拟区间数,提高计算效率,同时也可以满足计算精度的要求。计算结果表明,Taylor级数法暂态稳定计算的动态步长控制有效地提高了PEBS法的解算效益。PEBS(Potential Energy Boundary Surface)method is one of the TEF(Transient Energy Function)methods . The application of dynamic integral step control of Taylor series expansions in PEBS can simulate the sustained fault trajectory with large integral steps and avoid the redundant calculation in constant integration with satisfying precision . The numerical simulation tests demon - strate that the dynamic integral step control is useful in enhancing the efficiency of PEBS .
