Abstract: In order to improve the refined and intelligent management of energy in coal preparation plant, the energy monitoring platform of low-carbon coal preparation plant is designed using digital twin technology. Based on the establishment of the digital twin of washing process flow line in coal preparation plant, the corresponding production control algorithm model is established through the unsupervised control technology of power supply and distribution, the intelligent control technology of heavy medium whole process and the intelligent control technology of slime concentration, so as to carry out visual monitoring and control of electricity, medium, medicine and water energy in coal preparation plant. The application of the platform shows that the platform can realize such functions as intelligent control of production process, intelligent regulation of energy consumption and alarm of abnormal energy use in coal preparation plant, so as to promote energy saving and consumption reduction.
