摘要： PROBLEM TO BE SOLVED: To correctly monitor a load operation status without erroneous determination even when time variation exists in the load operation status. SOLUTION: A load operation status monitoring apparatus comprises a measurement means of change in the amount of consumed electricity to measure the amount of the consumed electricity of a power supply system in order to measure the change in the amount of the consumed electricity per predetermined period, a change pattern learning means to learn a change pattern of the change in the amount per predetermined period measured by the measurement means of the change in the amount of consumed electricity, and an abnormality detection means to detect abnormalities of a load operation status by comparing the change pattern learned by the change pattern learning means with the amount of change per predetermined period in an amount of actually consumed electricity measured by the measurement means of the amount of consumed electricity.
