中文摘要：
在对冲击电晕的伏库特性分析的基础上，通过将线路分为多个不长的小段，在每段线路两边插入考虑冲击电晕的附加电容，从而既计及了冲击电晕对电磁暂态的影响，又与现有的线路模型相兼容。通过雷击输电线路的电磁暂态仿真表明，考虑冲击电晕与不考虑冲击电晕的电磁暂态过程相差很大，因此在研究行波保护的雷电波抗干扰方法时应该考虑冲击电晕对电磁暂态过程的影响。
英文摘要：
On the basis of analyzing V-Q characteristic of impule corona, the influence of corona is considered by splitting the line into some short lines and inserting equivalent capacity of corona at both terminals of those short lines. As a result, both impulse corona and frequency-dependence line parameters are included in electromagnetic transient simulation. Lots of simulations show the results including corona are quite different from the results that ignoring corona. The influence of impulsive corona should be considered when lightning strike on line is studied.
