Intelligent Location and Analysis of Power Grid Fault Trip Based on Multi-source Data

China's southern power grid has been plagued by frequent disasters, such as lightning strikes, wildfires, ice and typhoons, and so on, which pose a great threat to the reliable operation of the grid. It is difficult to meet the requirement of automatic operation in the way of the traditional manual or limited fault location, cause analysis and failure summary analysis report. Data based on the fusion of all kinds of business system, realize the reason of the fault tripping device and automatic analysis, automatic generation of fault tripping analysis report, automatic push in monitoring system fault alarm and send real-time alarm messages. Fault tripping intelligent positioning analysis is helpful to quick accurate positioning, help operations staff in a timely manner to solve fault, quickly restore power, effectively reduce the operations staff report provided workload, improve work efficiency, thus effectively ensure the safe, stable and economic operation of power grid.
