PROBLEM TO BE SOLVED: To provide a power consumption estimation system for station-installed apparatus that can eliminate the trouble to install power meters corresponding to individual apparatuses and the cost for installing a communication network used to gather data from the individual power meters.SOLUTION: A power consumption estimation system for station-installed apparatus is configured to estimate individual power consumptions of a plurality of apparatuses installed in a station, and comprises a harmonic sensor 100 which is provided on a higher side of a power supply system supplying electric power to the respective apparatuses, and detects a waveform pattern of a current flowing the power supply system, a database in which waveform patterns detected by the harmonic sensor 100 and operation states of the respective apparatuses are associated and stored, and an information processing device 300 which estimates power consumptions of the respective apparatuses based upon the waveform pattern detected by the harmonic sensor 100 and the database. |
