The invention discloses a power system monitoring information objectification modeling method based on equipment, and the method comprises the steps: carrying out the fragmentation of a monitoring signal reflecting the condition of a power system through combining with the actual condition of power system equipment; carrying out model creation on all kinds of fragment modules; performing permutation, combination and splicing on the created perfect models to form intermediate models, and screening the intermediate models according to preset rules; and performing attribute solidification on thepower system monitoring information objectification model to realize electric power system monitoring information objectification modeling. According to the invention, an objectification model basis can be provided for data analysis, event alarm and decisive result deduction of advanced applications such as big data, regulation and control clouds and the like.
