说明：  提取故障发生时正向行波和反向行波的示例程序,本程序计算的是0模分量,设定仿真模型在0.035s时发生故障,故障分量取为从故障后的0.035s~0.039s减去故障前的0.015s~0.019s
(Forward traveling wave and reverse traveling wave sample program to extract a fault occurs, the program calculates the 0-mode component, set the simulation model in 0.035s failure, the fault component is taken as from the failure 0.035s ~ 0.039s less before the failure 0.015s ~ 0.019s)
