Abstract: As the hub node in the energy internet，the transformer can adjust and control power quality，the

normal and stable operation of transformer is of great significance to the safe and stable operation of the energy

internet. In order to accomplish this objective，status assessment of energy internet transformer based on immune

principle was proposed. Firstly，the transformer immunity model of energy internet was established by comparing

the similarity of human immunity and transformer status assessment. Then，association rules and constant weight

coefficient were used to judge the operating parameters，the health state of transformers was got. Finally，the

experiment verified the energy internet transformer status assessment model based on immune mechanism. The

results show that the proposed model can effectively complete the transformer health status assessment.
