| The lightning location system is a highly automated real-time lightning monitoring system with a high degree of automation,a wide monitoring area and accurate positioning information.The system uses the detector and communication system to achieve remote monitoring,you can calculate the lightning time,geographical location,lightning peak current and other parameters,through the lightning information system on the display visualization presented to the user.Many countries in the world will apply lightning protection technology to the lightning protection of power systems to help maintenance personnel quickly locate the lightning strike point,identify lightning accidents,and can provide lightning warning information.Lightning positioning monitoring technology in the extensive application of the grid to improve the power grid lightning warning and emergency response capabilities to protect the safe operation of the power grid.In this paper,the digital fourth-generation lightning location system for in-depth study.First,an overview of the history of lightning location system and its application to the study of the situation in the world,combing the lightning monitoring system in our country’s development process and introduced a new generation of lightning location system causes power grid construction in Beijing;then analyzes the transmission line the reason lightning damage suffered,mainly due to the insulating porcelain insulation is damaged transmission lines caused by lightning location detection principle studied,including alignment method,and integrated transit-time method;then a detailed study of the fourth generation the overall configuration of lightning location system,comprising a circuit schematic of the detecting portion stations,cloud-ground lightning flashes discrimination signal,the error analysis function and structure and layout principles station,a central portion preprocessor station,data server and a position analyzer,The actual application situation of the fourth generation lightning location system in Beijing power grid is introduced in detail,including the overall construction plan and the structural design of each part.In order to verify the actual effect of the system,by collecting measurement data,analyze a new generation of lightning Location The performance of the system in case of a lightning strike on the accident rate checking,lightning positioning and lightning statistics,the analysis showed that the new system has a high positioning accuracy,but also to the end the difference between the third and fourth generation systems were compared. |
