| 摘 要： | 在分析阻抗法测距技术与行波测距技术优缺点的基础上,提出一种新的嵌入式行波测距方法。通过将行波测距模块化,并以独立插件方式集成到线路保护装置中,既实现了完整的线路保护功能,还实现了完整的行波测距功能。并且行波测距模块复用线路保护装置的电流采样通道、光纤通信通道,共享线路保护故障数据与行波测距数据,提高了行波测距的准确性。

| Abstract: | The advantages and disadvantages of impedance fault location technology and travelling wave fault location technology are introduced,and a new embedded travelling wave fault location method is presented.By modularization of travelling wave fault location and its integration into a line protection device as an independent plug-in,the overall line protection function and travelling wave fault protection are implemented.Besides,the travelling wave fault location modular employs current sampling channel and optical fibre communication channel and shares line protection fault data and travelling wave fault location data,improving the preciseness of travelling wave fault location. |
