Abstract: Due to the large area, the distributed and remote substations in Tibet, and the low efficiency in detecting and treating hidden troubles in the secondary system, the relay protection function can not be fully developed. In order to meet the demand of power supply safety in this area, based on the existing fault information processing system, the logic rules and advanced functions are developed, the system software products are developed, and the second professional patrol inspection is upgraded from manual to automatic mode,to ensure the real-time and lean quality of the second round inspection.

Key words: relay protection, hidden danger treatment, professional patrol inspection, automatic upgrade
