POWER SOURCE CONTROL SEQUENTIAL STARTING SYSTEM

摘要

PURPOSE:To recover the start of rapid auxiliary devices by sequentially starting the devices operated before power interruption in the preferential order to fall the voltage drop within the prescribed range when a power source is recovered. CONSTITUTION:An auxiliary device operating state monitor 12 receives operating state monitoring data of auxiliary devices 30a-30n from a main switchboard 20, and stores the lift of the devices operated before power interruption. An auxiliary device starting sequence deciding unit 13 decides the starting order of the devices operated before the power interruption according to the list for deciding the starting sequence from a sequential starting list 11 and the list from the monitor 12. A sequential start controller 14 sequentially applies a start command to the devices 30a-30n according to the starting sequence so that the voltage drop of the bus 21 of the board 20 falls within the predetermined allowable range at the power recovery time.
