Title:
A standby-power-requirement estimating device, a program
Document Type and Number:
Japanese Patent JP6172601
Kind Code:
B2
Abstract:
An estimating apparatus includes an acquiring unit, a history recording unit, and a determining unit. The acquiring unit acquires power amounts for respective measurement times from a measuring apparatus that measures power for each branch line, as a plurality of used power amounts. The history recording unit records the plurality of used power amounts in association with dates and times. The determining unit variably sets a comparison value for comparing magnitudes of the plurality of used power amounts recorded in the history recording unit, obtains a minimum value of the comparison value in a range satisfying a condition that an amount of time for which at least some of the plurality of used power amounts are continuously equal to or below the comparison value exceeds a prescribed sustained time, and estimates the minimum value to be a peak value of stand-by power of the branch line.
