主控系统是指燃气轮机的连续调节系统,单轴燃气轮机控制系统设置了几种自动改变燃气轮机燃料消耗率的主控制系统和每个系统对应的输出指令--FSR(FUELSTROKEREFERENCE 燃料行程基准)，此外还设置了手动控制燃料行程基准。

上述4个IS200TDBTH6ACD ，IS200TDBTH6ABC，IS200ERIOH1AAA IS200JPDDG1AAA FSR量进入最小值选择门，选出6个 FSR 中的最小值作为输出，以此作为该时刻实际执行用的FSR控制信号。因而虽然任何时刻6个系统各自都有输出，但只有一个控制系统的输出进入实际燃料控制系统

启动控制系统仅控制燃气轮机从点火开始直到启动程序完成这一过程中燃料Gf(在 Mark-V系统中通过启动控制系统输出 FSRSU)。

燃气轮机启动过程中燃料需要量变化范围相当大。其最大值受压气机喘振(有时还受透平超温)所限，最小值则受熄火极限或零功率所限。

这个上下限随着燃气轮机转速大小而变，在脱扣转速时这个上下限之间的范围最窄。

The main control system refers to the continuous regulation system of the gas turbine. The single-axis gas turbine control system sets up several main control systems that automatically change the fuel consumption rate of the gas turbine and the corresponding output instruction -FSR(FUELSTROKEREFERENCE fuel stroke reference) for each system, and also sets the manual control fuel stroke reference.

The above four IS200TDBTH6ACD, IS200TDBTH6ABC, IS200ERIOH1AAA IS200JPDDG1AAA FSR quantities enter the minimum value selection gate, and select the minimum value of the six FSRS as the output, which is used as the FSR control signal for actual execution at this time. Thus, while each of the six systems has an output at any given time, only the output from one control system goes into the actual fuel control system

The start control system only controls the fuel Gf of the gas turbine from the start of ignition until the completion of the start procedure (in the Mark-V system FSRSU is output via the start control system).

Fuel requirements vary widely during start-up of gas turbines. Its maximum value is limited by compressor surge (and sometimes by turbine overtemperature), and its minimum value is limited by flameout limit or zero power.

This upper and lower limit varies with the gas turbine speed, and the range between these upper and lower limits is narrowest at trip speed.
