| 摘 要： | 输电线路发生故障后，故障点将产生向变电站母线运动的行波，采集记录在母线处测到的故障电流行波波形，运用适当的算法，即可实现输电线路精确故障测距。根据此原理成功研制了以新型数字信号处理器ＴＭＳ３２０Ｃ３２ 为核心的测距系统，并介绍了系统的硬件构成和软件设计。通过模拟仿真试验和现场试运行，运行结果表明，此装置具有很高的测距精度。

| Abstract: | The failure point will produce traveling wave towards electric substation trunk when transmission circuit failure occurs.Precise failure distance measurement is performed by collecting and recording the traveling wave shape of the failure current measurement at the trunk and applying suitable algorithm.Based on this principle,a distance measurement device with the new digital signal processor TMS320C32 being its core is successfully developed,and the hardware constitution and software design is introduced.Simulation tests and field running indicates that this device has a high accuracy for measuring distance. |
