PROBLEM TO BE SOLVED: To easily and accurately provide power consumption and the like of individual electric appliances such as variable-load household electric appliances, i.e., household electric appliances whose power consumption (current) varies in accordance with modes, settings or the like.SOLUTION: A state estimation part uses total sum data regarding total current consumed in a plurality of electric appliances to perform state estimation that obtains operational states of the electric appliances. A constrained waveform separation learning part performs waveform separation learning, which obtains specific waveforms regarding current specific to the operational states of the electric appliances, under constraints specific to the electric appliances. This technology can be applied, e.g., in order to obtain power consumption of variable-load household electric appliances. |
