摘　　要：通过对汽轮燃油泵调节系统的合理简化,建立了组成元件的模型方程,并对机组调节系统的动态特性进行了基于传递函数方法的仿真计算。结果表明该汽轮机的调节系统具有良好的动态性能,超调现象不明显。较之蒸汽压力和泵阻力,工况调节器对转速的影响更大。通过对比仿真计算结果与试验曲线,表明二者一致性较好。By the reasonable simplify on the regulating system of fuel pump steam turbine,the model equations of components were found.The transfer function method was used to simulate the dynamic characteristics of the regulating system and the simulated curve is.The results showed that the regulating system had high dynamic quality,the overshoot was small.Compared with steam pressure and pump resistance,the condition regulator had a greater effect on rotating speed.By comparing the simulation results with the test curve,good agreement was obtained.
