PROBLEM TO BE SOLVED: To provide a system for estimation of an electrical apparatus operation state, capable of efficient estimation not requiring learning.SOLUTION: The electrical apparatus operation state estimation system is provided for estimating operation states of a plurality of electrical apparatus connected to the same feeder. The system includes a characteristic quantity extraction means for extracting information of the waveform of a current flowing through the feeder, and an individual apparatus information storage means for storing information of the current waveform when only an electrical apparatus is operated relative to each electrical apparatus. The system also includes an electrical apparatus operation state estimation means for acquiring estimation results of the operation states of the plurality of electrical apparatus by executing genetic algorithm wherein a combination of the operation states of the plurality of electrical apparatus is assumes as an individual gene arrangement, and one or a plurality of information of the current waveform are acquired from the individual apparatus information storage means based on the individual gene arrangement, and evaluation is performed by forming information to be compared with extracted information of the waveform of the current flowing through the feeder. |
