为保证重型燃气轮机高温部件全场主流空气系统调节的全面性和灵活性，基于仿真技术实现了对燃气轮机高温部件试验设施空气系统的调节过程计算，得到了试验段与气源侧流量、压力和温度等状态参数的变化曲线，分析了气源温度、阀门开度及连锁控制对试验运行的影响，并确定了运行控制应对方案。结果表明：试验设施进气系统和排气系统并联的方案可以将试验段流量和压力的调节进行解耦；进气系统和排气系统对应配置的并联阀组与背压阀组可以通过联锁控制确保气源压缩机组和试验段的稳定运行。

In order to ensure the comprehensiveness and flexibility of the mainstream air system regulation for the high temperature components of heavyduty gas turbine,simulation software was used to simulate the adjustment process of the mainstream air system,and the change curves of the flow rate,pressure and temperature of the test section and air sonrce sides were obtained.The influence of air source temperature,valve opening and interlock control on test operation was analyzed,and the optimized operation parameters were determined.The results show that the flow rate and pressure regulation of the test section can be decoupled by means of parallel air inlet and air outlet.The parallel valve group and back pressure valve group corresponding to the intake system and exhaust system can be controlled by interlocking to ensure the stable operation of the air source compressor unit and the test section.
