摘　　要：以某燃煤电厂压缩空气系统为研究对象,建立了该压缩空气系统能耗模型、管网压力模型、试验验证模型和Simulink仿真模型,通过试验验证了所建的数学模型及仿真模型的有效性。为了降低该电厂压缩空气系统的能耗,利用仿真和试验手段优化了压缩空气系统的运行,结果显示,该电厂压缩空气系统具有较大节能空间,通过优化运行达到了较好的节能效果。Taking the compressed air system of a coal-fired power plant as the research object,this paper establishes four models with regard to the compressed air system,including the energy consumption model,the pipe network pressure model,the test verification model and the Simulink simulation model.Then we verify the validity of these models by means of experiments.In order to decrease energy consumption of the compressed air system in the power plant,this passage optimizes the operation of the compressed air system by means of simulation and trial.The result shows that the compressed air system of the power plant has great energy-saving potential and achieves better energy-saving effect by optimizing operation.
