Patent Searching and Data


Title:
エネルギー管理装置、プログラム
Document Type and Number:
Japanese Patent JP5834252
Kind Code:
B2
Abstract:
Acquiring unit acquires, as power usage amount, amount of power for each measurement time, for each of branch lines through which power is fed to electrical loads, respectively. History storage unit stores a plurality of power usage amounts for each branch line so that each amount is made to correspond to time and date when acquired. Analyzing unit calculates frequency distribution of magnitudes of power usage amounts during target period, of the plurality of power usage amounts in history storage unit, and estimates that power usage amount in which cumulative relative frequency from lower limit of power usage amount is frequency threshold or more is amount of standby power. Analyzing unit determines whether electrical load corresponding to each branch line is in operation by setting standby power to reference value and comparing reference value with magnitude of power usage amount. Determined result is displayed on display device.
