摘要：
As the key product application of fault location service for ultra-high voltage (UHV) transmission system, the distributed fault diagnosis system of transmission line is of great significance to the safety, reliability and economic operation of power system. By combining the development and application of practical system, this paper proposes a secure link application method for distributed fault diagnosis and monitoring terminal system based on security protection. This method uses the monitoring terminal embedded encryption chip to access the security gateway. After filtered by the security gateway, the access to the monitoring and maintenance center can be done. Isolated by the forward device, the monitoring and maintenance center sends message to App server station one way by means of identity authentication and digital signature, and the App server establishes a secure channel for mobile terminal. Through the trusted transformation of the entire link, malicious program attacks, malicious code implantation attacks, network eavesdropping and sniffing attacks are effectively prevented. By the identity checksum of the monitoring and maintenance center and the backup of the dual-machine data of the main/standby machine, the security of data and maintenance operation of the monitoring and maintenance center are guaranteed. The described system products have successfully passed the safety test and certification, and run steadily and reliably on the 1 000 kV UHV AC transmission line in Shaanxi Province of China. © 2019 Automation of Electric Power Systems Press.
