电厂输煤自动控制系统节能优化方法研究

Study on Energy-saving Optimization Method of Automatic Coal Control System in Power Plant

传统的匀速输煤模式虽然可以保证煤的供给从而保障电力供应,但是却不符合节能发展的目标。针对此问题,文章首先分析了输煤系统的工作流程,并针对输煤系统的工作模式,推理了煤需求量与时间的关系。其次基于预测控制建立了输煤控制系统闭环优化模型,并推理了状态方程。最后针对预测控制中的误差问题,引入了反馈校正,以实现误差优化。实验结果表明,使用闭环优化方法可以实现能源与经济的双重节约。

Although the traditional uniform-speed coal transmission mode can absolutely guarantee the supply of coal to guarantee the power supply,it does not meet the goal of energy-saving development.To this problem,the workflow of coal transmission system was analyzed,and the relationship between coal demand and time for the working mode of coal transmission system was derived.Based on predictive control,a closed-loop optimization model of coal transmission control system was established,and state equations were reasoned.At the same time,the feedback correction was introduced to optimize the error as far as possible.The experimental results showed that the closed-loop optimization method could realize the control and provided energy-saving optimization.
