Abstract: To solve the energy consumption simulation problem in production process of continuous process enterprises, the coupling relationship between enterprise production and energy consumption were studied, as well as related concepts such as principal device and principal speed were proposed. The method of continuous Petri net was employed to set up production and energy consumption process model with coupling information parameters for continuous process enterprises. Based on enterprise production planning, a production dispatching method was put forward to model energy consumption process, and the proposed method was verified by simulation experiment. The materials were divided into five types：raw materials, intermediate products, export products, final products and emissions. On these basis, energy flow, material flow and information flow in production energy consumption process were simulated effectively. It could help to manage and balance energy consumption in continuous process enterprises.
