Title:
ELECTRIC ENERGY CALCULATION DEVICE AND ELECTRIC ENERGY CALCULATION SYSTEM
Document Type and Number:
Japanese Patent JP2014153337
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To reduce deviation between the measurement value of a power measurement device and the measurement value of a power meter, and to show the transition of integral power consumption in detail.SOLUTION: In a management device (electric energy calculation device) 1, a first communication part (communication part) 11 acquires the measurement value of integral power consumption from a power meter 5 which measures a power to be supplied from an electricity undertaker to a client by communication at a first time interval, and acquires an instantaneous power value indicating the scale of an instantaneous power to be supplied from the electricity undertaker to the client at a second time interval shorter than the first time interval, and the calculation part of an arithmetic part 13 acquires the latest integral power consumption at a point of time when the first communication part 11 acquires the instantaneous power value by using the measurement value of the integral power consumption acquired by the first communication part 11, the instantaneous power value acquired by the first communication part 11 and the second time interval, and a second communication part (output part) 14 outputs the calculation result of the calculation part to a monitor 6.
