The embodiment of the invention provides an industrial device energy consumption reference value calculation method and system based on machine learning, and the method comprises the steps of obtaining the operation data of an industrial device, and arranging the operation data to obtain an operation data set; constructing a reference value calculation initial model on the basis of a machine learning algorithm; importing the operation data set into the reference value calculation initial model to obtain a reference value calculation model representing the actual operation state of the industrial device; and inputting the characteristic value into the reference value calculation model to obtain an energy consumption reference value outputted by the model. The industrial device energy consumption reference value calculation model is established based on the machine learning, so that the actual industrial device operation data and other data related to the industrial device operation dataare collected to serve as data sources of modeling, and it is guaranteed that the calculation result better conforms to production practice.
