| 摘 要： | 电容式电压互感器高频响应特性差，满足不了对电压行波测量的要求。该文利用测量电容式电压互感器（CVT）的入地电流行波来检测线路电压行波，设计了行波传感器，提出了硬件行波波头检测方法，并应用于基于整个电网的行波故障定位。仿真分析及装置实验测试表明：该方法实现简单、安装方便、鲁棒性强、定位精度高。该技术巳申请国家发明专利。

| Abstract: | The voltage traveling-wave in transmission line is difficult to be accurately detected in the secondary of capacitive voltage transformer (CVT) which has bad character to transform high frequency signals. A new sensor to detect the voltage traveling-wave is designed in this paper. It can measure the current traveling-wave from CVT to ground. The incipient times of traveling-wave appearing in every station are measured and a new fault location system for the whole grid is implemented. Simulations and prototype testing show that this fault location method has high precision and can be implemented easily and cheaply. |
