With the development of smart grid and the rapid growth of power grid scale

it is faced with huge prob-lems and challenges to master the status of power equipment timely and accurately. The precise operation and mainte-nance of power grid equipment puts forward an urgent demand for the transparency of the real state of power equip-ment. The development of the new generation of information technology

such as"cloud computing

big data

IOT

mobile internet

and AI"

provides the basic conditions for the intelligence of traditional power equipment. In thiscontext

according to the modern control theory and reliability engineering theory

combined with the needs of opera-tion and maintenance of power equipment and the research status at home and abroad

this paper puts forward the es-tablishment method of power equipment state space model based on failure mode analysis

the establishment methodof power equipment engineering simulation calculation model based on the correction of failure mode test data

andthe establishment method based on power equipment. The establishment method of power equipment state evaluationmodel with panoramic data fingerprint database provides a new research idea for the intelligent power equipment

hoping to have some reference significance for the development of intelligent power equipment.
