Abstract
Relay protection is to guarantee the safe and stable operation of the power system, and setting value is the key to ensure the protection correct action. In this paper, given the wiring and the parameters of 110kV power grid, according to power system protection relay configuration and setting principles and develop a whole network relay protection and automatic device configuration, on the line protection, transformer protection terminal for setting calculation, by check, in line with sensitivity requirements. UPSs English name is Uninterruptable Power System, the Chinese name is uninterruptible power supply actually means AC uninterruptible power supply, the main function is to provide uninterrupted AC power to the load. The design of the substation for uninterruptible power supply (UPS) system theory and operation were analyzed. Produced multimedia courseware. Beautiful and flexible so that the subject of multimedia courseware for a visual image of the contents are displayed.
Key words: relay protection, setting calculation, UPS
