摘　　要：为确保电力系统的平稳运行,需要排除故障对输电线路的干扰。文章提出一种基于故障录波数据的故障检测方法,以实现线路的故障排除和维护。利用故障录波器提取线路电流、电压数据,并利用数学形态学滤波器对数据进行降噪处理,通过黄金分割搜索算法和相关系数计算对故障位置进行精确定位。试验结果表明,所设计方法具有较高的检测精度,测距相对误差小于0.001%。利用所设计的故障检测方法对输电线路进行日常巡检,可实现故障排除以及输电线路的运行维护,为电力用户提供稳定的电力供应服务。In order to ensure the smooth operation of the power system,it is necessary to eliminate the interference of the fault to the transmission line.In this paper,a fault detection method based on fault recording data is proposed to realize the fault elimination and maintenance of the line.The fault recorder is used to extract the current and voltage data of the line,and the mathematical morphological filter is used to denoise the data,and the fault location is precisely located by the golden section search algorithm and correlation coefficient calculation.The test results show that the designed method has high detection accuracy and the relative error of distance measurement is less than 0.001%.Using the designed fault detection method to carry out routine inspection of transmission lines,it can realize fault removal and operation and maintenance of transmission lines,and provide stable power supply service for power users.
