POWER SUPPLY CONTROL DEVICE

摘要

A power supply device connected to a trunk line in a switchboard after a power source breaker is opened in response to the detection of power outage, a personal computer identifies from among loads a load to which power can be supplied within the range of output capacity of the power source supply device and connects the load identified to the trunk line. A user may assign priorities to some or all of the loads. Although the personal computer identifies the loads to be connected in order of the priority, when a total power consumption of the identified loads exceeds the limit of output capacity of the power supply device, the personal computer skips the load to be identified in order of the priority and attempts to identify a load with a lower priority.

1. A power supply control device that controls power supply from a power source device to a plurality of loads comprising:
a circuit that parallely connects the plurality of loads to the power source device; a plurality of switches provided to the circuit, wherein the switches respectively switch between a connection and a shut off between the power source device and the plurality of loads; a priority setting unit that assigns priorities to the plurality of loads; a load identifying unit that repeatedly performs a load identifying process on all of the plurality of loads, wherein the load identifying process selects one load from the plurality of loads according to the priority, identifies the selected load as a connection target when a total power consumption by the selected load and a load that is already identified as a connection target is not greater than an upper output limit that is set according to an output capacity of the power source device, and does not identify the selected load as the connection target when the total power consumption by the selected load and the load that is already identified as the connection target is greater than the upper output limit; and a changeover control unit that controls a changeover of the switch corresponding to the load that is identified as the connection target by the load identifying unit and to connect to the power source device the load that is identified as the connection target.
