Method for correcting a power usage measurements between power usage measurement meter

摘要

The present invention relates to a method for calibrating a measurement value between power consumption measurement meters. The method for correcting power consumption measurement according to the present invention is a method for compensating a power consumption using a first power consumption measured in a unit time and a second power consumption measured in a time difference range of the unit time based on a notation of the first power consumption step; Calculating a time difference value between a time when the error between the first power consumption amount and the second power consumption amount becomes minimum and the notation point by comparing the first power consumption amount and the second power consumption amount; And generating a correction function for correcting the power consumption using the time difference value. According to the present invention, by applying the correction function reflecting the time difference between the notation time and the measurement time of the utility meter to the sub meter measurement value and reflecting the efficiency of the transformer, it is possible to more accurately estimate the measurement amount of the utility meter have.
