摘　　要：介绍了消除数值振荡的特征差分法及其在合闸 (单相重合闸 )操作过电压、金属氧化物避雷器耗散能量、线路绝缘统计故障率的数值计算中的应用 ,计算表明 ,该方法可有效地消除数值振荡。计算结果与 BPA、EMTP及 TNA实测结果比较 ,一致性良好。A characteristic difference method and its applications in the numerical calculation of energization overvoltage (single phase re energization overvoltage), energy dissipation of metal oxide arrester (MOA) and statistical failure rate of transmission line insulation are presented. The calculation results show that the numerical oscillation can be effectively removed by the method. Comparisons show that the calculation result from this method well coincides with that from BPA, EMTP and TNA, thus this method can be used in engineering numerical calculations and engineering designs.
