| 摘 要： | 在电力系统行波对高频保护的影响的相关理论的基础上,通过matlab软件的Simulink模块,对其进行仿真研究。仿真结果表明,在电力系统发生故障后,故障电气量以行波的方式在输电线路上传输的过程中产生了时延。因此,在高频保护设计中,应该将此考虑进去。

| Abstract: | Through Simulink mode of matlab software, the impact of travelling wave of power system on high frequency protection is studied based on the relative theories. Simulation results show that the fault electric quantity travelling wave lead to time-delay on the lines after the power system fault. Therefore, this should be considered while designing the high frequency protection. |
