Discussion on Key Techniques of Operation,Maintenance and Troubleshooting of Transmission and Distribution Lines
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.
