APPARATUS AND METHOD FOR ESTIMATING OPERATING STATE OF INDIVIDUAL LOAD

摘要

The present invention relates to a device and a method for estimating the operation status of the individual loads present in a building at a low cost. According to the present invention, the individual load operation status estimation method includes the steps of: generating an operation status table mapping the total sum of the electrical parameter values for the individual loads which are subjected to an operation status estimation operation with the operation status of the individual loads; measuring the total sum of the electrical parameters; inquiring the total sum of the electrical parameters corresponding to the total sum measured in the previous step in the table to estimate the operation status of the individual loads.
