摘　　要：在对高频信号及故障信号进行频谱分析的基础上,针对不同位置不同故障类型做了大量仿真测试,对暂态量保护在高频信号干扰下的可靠性进行了研究。This paper carried out many simulation tests for different positions and different types of fault. These tests were based on the frequency spectrum analysis of high-frequency signal and faulty signal. Meanwhile, research on rite reliability of transient-based protection under the interferer of high frequency signal was performed.

关 键 词：暂态量保护 载波机 高频信号 可靠性
