燃油系统的时滞特性会对燃气轮机的动态性能造成显著影响，集成仿真模型是复现这种复杂动态过程的有效工具，尤其是对于负荷突变的恶劣工况。基于燃气轮机与燃油系统模拟装置的结构和工作原理建立了一个多学科的燃气轮机多系统集成模型，并搭建了发电燃气轮机半物理仿真实验台，进行变工况仿真。结果表明，燃油系统的时滞特性会减弱突变负荷时燃气轮机的燃油调节能力，降低燃气轮机的稳定性，同时导致燃气轮机动力涡轮转速的瞬态调速率增大，在0.2～0.4工况的加载过程中瞬态调速率增大了44.36%，0.4～0.6工况的加载过程中增大了29.75%。
The delay characteristics of fuel system will significantly affect the dynamic performance of gas turbine, and the integrated simulation model is an effective tool to reproduce this complex dynamic process, especially for the severe load sudden change. Based on the structure and working principle of the gas turbine and fuel system simulation device, a multi-disciplinary gas turbine multi-system integration model is established, and a semi-physical simulation test platform is built to simulate the gas turbine under varying operating conditions. The results show that the time delay of the fuel system will weaken the fuel regulation ability of the gas turbine under sudden load, reduce the stability of the gas turbine, and lead to the increase of the transient adjustment rate of the gas turbine power turbine speed, which increases by 44.36% in the loading process from 0.2 to 0.4, and 29.75% in the loading process from 0.4 to 0.6.
