Abstract: Introduction was made to the logic of automatic switch-on function of 220 kV standby power supply. Combined with onsite usage condition, this paper analyzed switch status setting for main supply lines, standby supply automatic switch-on lines, standby supply automatic switch-on busbar connection. Causes of charging and discharging conditions were described according to lines standby automatic switch-on and busbar connection standby switch-on. This paper analyzed standby automatic switch-on starting logic and combined logic sequence to simulate standby automatic switch-on starting and to list action result step by step, which provides basis for acceptance of 220 kV standby power supply automatic switch-on device.
Key words: standby power supply; standby power supply automatic switch-on; bus bar; charge; discharge
