POWER DISPLAY TERMINAL, POWER MANAGEMENT DEVICE, POWER DISPLAY METHOD, AND PROGRAM

摘要

PROBLEM TO BE SOLVED: To display power consumption information per household so that a total value accords with a value announced by a power company even if current sensors make their individual measurement error.SOLUTION: A power display terminal (10) according to the present invention comprises: a communication unit (11) that obtains an integral power consumption during a prescribed period of power supplied to first and second regions from a system from a smart meter (30), and obtains measurement values of integral power consumption in the first and second regions during the prescribed period measured by current sensors (60A, 60B); a control unit (15) that compares the integral power consumption with the total value of the measurement value of the power consumption in the first region and the measurement value of the power consumption in the second region, and calculates a compensation coefficient to correct the measurement values by the current sensors; and a display unit (13) that displays the corrected amount of power consumption in the first and second regions by applying the correction coefficient.SELECTED DRAWING: Figure 1
