摘　　要：某电厂的660 MW超超临界汽轮机组需要优化运行方式,提高节能水平。研究过程针对该汽轮机组开展热力试验,采集运行数据,通过数学方法拟合出主蒸汽压力和热耗率数学模型,建立了阀门节流损失的计算方法,在此基础上形成汽轮机和回热系统的变工况模型。基于以上模型开展理论分析,同时利用工程平台进行试验,最终提出超超临界汽轮机组的节能安全运行措施,改进了主汽阀门开度的调节范围和变负荷条件下的汽轮机运行参数,取得了良好的效果。The 660 MW ultra-supercritical steam turbine unit of a power plant needs to optimise its operation and improve energy saving.The research process carries out thermal tests for this turbine unit,collects operation data,fits a mathematical model of main steam pressure and heat consumption rate through mathematical methods,establishes a calculation method of valve throttling loss,and forms a variable operating condition model of the turbine and heat return system on this basis.Based on the above model,theoretical analysis is carried out,and at the same time,tests are conducted using an engineering platform,and finally,energy-saving and safe operation measures are proposed for the ultra-supercritical steam turbine unit,and the adjustment range of main steam valve opening and turbine operation parameters under variable load conditions are improved,and good results are achieved.
