| 摘要: |
| 为了检验行波测距装置的运行状态，并提高检验的准确性，针对双端测距的校验，提出了基于历史故障波形的行波测距装置检验方法。利用行波测距装置记录的历史故障行波作为测试波形，加载到高频行波信号源并以GPS同步的方式输入被测线路两端的行波测距装置。利用该方法得到的测距结果与历史故障测距结果进行了对比分析。现场测试结果表明，基于历史故障波形的行波测距装置检验方法是有效和实用的。该方法能准确检验行波测距装置的运行状态，继而保障了输电线路安全稳定地运行。 |

| Abstract: |
| In order to test the operation state of travelling wave fault location equipment and improve the inspection accuracy, a method of inspection for double-ended fault location based on historical fault waveforms is proposed. This method uses the historical fault waveforms which were recorded by the travelling wave fault location equipments as the testing waveforms, loads them on HF travelling wave source, and inputs the testing waveforms into both sides of the traveling wave fault location equipment by the GPS synchronous devices. The master station of the fault location system calculates the ranging results, and compares them with the historical fault distance of testing waveforms. The site test results verify the effectiveness and practicality of this method. This method can accurately inspect the operation state of the traveling wave fault location equipment, thus protects the operation transmission lines operating safely and steadily. |
