摘要
在对Taylor级数法暂态稳定计算的计算量进行定量分析的基础上，根据计算精度的要求，提出了Taylor级数法暂态稳定计算中阶数的动态控制。分析与计算结果表明，由于在计算过程中按计算精度的要求动态选取求导阶数，从而在保证计算精度的前提下，有效地提高了Taylor级数法暂态稳定计算的解算效益，具有实用价值。
Based on the analysis of amount of computation and calculation precision of fast transient stability simulation by higher order Taylor series expansions. a concept of dynamic control of order selection is proposed. in which the order for fast transient stability calculation is dynamically selected under the requirement of calculation precision. The numerical simulation tests demonstrate that the dynamic control of order selection improves the calculating efficiency greatly and has practical value in transient stability simulation and analysis of power systems.
