<p>Provided is a protection control monitoring device in which both the reproducibility of information and the reduction of the amount of information to be stored can be achieved. The protection control monitoring device comprises: a conversion unit for sequentially converting analog data corresponding to the amount of electricity of a power system to digital data and outputting the results as a data sequence; a calculation unit for sequentially calculating difference data indicating the difference between adjacent data in the data sequence and outputting the results as a difference data sequence; a data block generation unit for dividing each of the difference data in the difference data sequence into a plurality of partial data, generating data blocks from the corresponding partial data, and outputting the results as a data block sequence; a compression unit for losslessly compressing the data block sequence; and a storage unit for storing the losslessly compressed data block sequence.</p> |
