The method comprises the following steps: acquiring molecular data with target electronic attributes; taking the fragment of the molecular structure as the input of the model, and designing a new additive molecular structure by utilizing the molecular generation model; performing molecular screening according to target characteristics; and the performance of the screened molecules is verified through streamer discharge simulation. According to the method, generative design of ester-based insulating oil additive molecules is realized by using the deep autoregressive neural network, the molecular screening efficiency is remarkably improved, and a new technical route is provided for improving the breakdown voltage performance of the ester-based insulating oil.
