Simulation results indicate that the model effectively represents the mid-high process of coal mill dynamics and can be used to estimate the key parameters in coal mills, which are difficult to measure or cannot be measured. On this basis, the model can be used for the state monitoring, control optimization, and fault diagnosis of coal mills.

The operation state of coal mill is related to the security and stability operation of coal-fired power plant. In this paper, a fault diagnosis method of coal mill system based on the simulated typical fault samples is proposed. By analyzing the fault mechanism, fault features are simulated based on the model of coal mill, and massive fault samples are obtained.

The coal mill used in the coal-fired power plants is modeled in view of the controller design rather than the educational simulator. The coal mass flow and the outlet temperature are modeled by reinvestigating the mass balance and heat balance models physically. The archived data from a plant database are utilized to identify the model parameters.
