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.
