摘　　要：针对绝热压缩空气储能系统中的透平滑压运行参数进行研究,以某项目100MW空气透平为例,介绍了储气方式和储气参数对空气透平的影响,提出了以单位质量发电量作为压缩空气储能透平性能指标的考核办法。对于全周进气加补气阀的进气调节方式,核算出了9.8MPa~3.7MPa滑压范围内各个补气阀开启点压力对应的单位质量发电量,通过对比确定最佳的补气阀开启点压力为7.3MPa,此时发电效率与纯补气方案相比提高2.7%,与纯节流方案相比提高12.6%,具有明显效率提升效果,对其它压缩空气储能透平进气调节方式选型具有明显参考意义。In this paper,the sliding pressure operation parameters of turbine in adiabatic compressed air energy storage system are studied.Taking a 100MW air turbine in a project as an example,the influence of gas storage method and gas storage parameters on the air turbine is introduced,the influence of the air storage method and parameters on the air turbine is introduced,and the evaluation method of taking the power generation per unit mass as the performance index of the compressed air energy storage turbine is proposed.For the intake adjustment method of the whole-week intake and air supply valve,the power generation per unit mass corresponding to the pressure at the opening point of the air supply valve in the range of 9.8MPa~3.7MPa under each sliding pressure condition is calculated.Through comparison,it is determined that the optimal opening point pressure of the air supply valve is 7.3MPa.At this time,the power generation efficiency is increased by 2.7%compared with the pure air supply scheme and 12.6%compared with the pure throttling scheme,which has obvious efficiency improvement effect,and has obvious reference significance for the selection of other compressed air energy storage turbine intake adjustment methods.
