Ajax-based information publishing system for traveling wave fault location

In order to real-time issue high precision faults location results for fault treatment, a Web based fault information publishing system for power grid traveling wave fault location is designed in the paper. The system adopts three-layer frame based on Browse/Server (B/S) mode, and uses Microsoft IIS 5.1 as Web Server. Ajax (Asynchronous JavaScript and XML) technique is applied to realize the location results release in real-time, which can create more dynamic and highly available web user interfaces (close to a local desktop application). In addition, a detailed study is carried out for data security. The software has been applied in a real electric power network, practical operation results show that the software can release faults information dynamically and share faults data safely.
