Autonomous Decision Control of Start-Stop Timing for Coal Mills

Based on the characteristics of the start-stop timing of coal mills, an economic and flexible return function was designed to evaluate the quality of the start-stop timing. By utilizing intelligent decision-making algorithms, the optimal start-stop timing for coal mills was determined and validated through simulation on a certain ultra-supercritical 1000MW unit. The results demonstrate that by making optimal decisions regarding the start-stop timing, it is possible to save auxiliary power consumption while ensuring the flexibility of the milling system. This approach provides convenience for operators and improves the automation level of the unit.
