Publishing Technology Based on Multi-server for Distributed Fault Diagnosis Information

Distributed line fault diagnosis system and information release technology are of great significance to grid security operation and maintenance. Combined with the development and application of the actual system, a multi-server based distributed fault diagnosis information security releases technology is proposed. From the source of device data to the end of publishing terminal, take various technical means such as security output, secure access, and network isolation to achieve information security. Real-time and consistency of data is achieved through multi-server deployment, physical isolation of servers, and real-time synchronization of heterogeneous databases. The principles of network security access and network isolation are described in detail. The security interaction between the monitoring center server and the mobile App server, information synchronization, module design and implementation methods are successfully certified by the China Electric Power Research Institute and implemented in Shanxi Province. High-voltage AC 1000 kV transmission line running on the network.
