摘　　要：现货市场模式下,火电机组启停频繁,而大型火电厂由于机组数量多,机型构成复杂,深度调峰和启停调峰时厂用汽系统会出现较多的问题,影响机组安全经济运行。文章以某电厂为例,探讨了厂用汽系统的改造方案,通过1种方案同时达到了节能改造、灵活性改造、供热改造的效果,具有成本低、收益高、效果好的特点,同时推动了三改联动技术的进步,为大型火电机组实现三改联动提供了新的思路。In the spot market model,thermal power units start and stop frequently.Due to the large number of units and complex model composition in large-scale thermal power plants,there are many problems in the plant steam system during deep peak shaving and start-stop peak shaving,which affects the safe and economic operation of the units.Taking a plant as an example,this article discusses the transformation plan of the plant steam system.Through a plan that achieves the effects of energy-saving transformation,flexibility transformation,and heating transformation.It has the characteristics of low cost,high yield and good effect,which promotes the progress of the three reforms and linkage technology and provides a new idea for large-scale thermal power units to achieve the three reforms and linkage.
