In order to accurately detect the operation status of transmission lines,an intelligent inspection system for transmission lines based on Beidou positioning technology is designed.The equipment layer uses the digital fault indicator to detect the operation status of the transmission line and accurately locate the fault section according to the section positioning algorithm,obtain the detection data,and use the Beidou communication sub module to transmit the detection data to the Beidou command aircraft.The transmission layer uses the Beidou command aircraft to transmit detection data to the application layer.The application layer uses GIS to obtain the visual detection data,and transmits the visual detection data to the data management module and equipment monitoring module to obtain the operation status of the transmission line.The experimental results show that the system can accurately locate the fault section of transmission line under different distributed generation permeability and different fault types.The line fault data is increasing,and the alarm leakage rate of the system is always lower than 1.5%.
