Operation control method, system and device for coal pulverizing system of coal-fired thermal power plant

The invention relates to an operation control method, system and device for a coal pulverizing system of a coal-fired thermal power plant. The operation control method specifically comprises the following steps: acquiring real-time data of the coal-fired thermal power plant pulverizing system; inputting the real-time data into a coal pulverizing system energy consumption prediction model, and respectively obtaining prediction data of unit consumption and power consumption of the coal pulverizing system; and setting a coal pulverizing system control strategy according to the prediction data, and controlling the operation of the coal pulverizing system. Compared with the prior art, the operation control method predicts and analyzes the energy consumption conditions of the coal mill and the primary air fan through the energy consumption prediction model of the coal pulverizing system, selects the optimal operation control strategy of the coal pulverizing system according to the predictionresult, then controls th
