摘　　要：为提升分轴燃气轮机突卸负荷时的调速性能,降低瞬态调速率,减少达到稳定所需的时间,提出了根据负载信号等参数来进行判断,在油气比开环、转子加速度闭环之间进行切换控制的模式。搭建了过渡态仿真模型,采用隐式的CMF方法对某型燃气轮机突卸100%负荷时的燃气轮机气动参数进行了仿真,同时对整机突卸100%负荷进行了试验验证。整机气动参数的试验与仿真的对比结果验证了燃气轮机达到了产品验证合同要求。研究成果可以为燃气轮机突卸负荷控制逻辑设计及仿真提供参考。For a split-shaft gas turbine under condition of sudden load shedding,to improve the speed regulation performance,reduce the transient speed regulation rate and decrease the stabilization time,a control mode that could switch between the open-loop fuel-air ratio and closed-loop rotor acceleration control based on parameters,such as load signals,was proposed.A transition state simulation model was established,and the implicit CMF method was adopted to simulate the aerodynamic parameters of a certain type of gas turbine under condition of 100% sudden load shedding.Afterwards,test was carried out on the same condition to verify the mode.The results of the aerodynamic parameters compared between the test under 100% sudden load shedding and simulation validated that this gas turbine had reached the requirements of the product verification contract.The research findings can provide reference for design and simulation of control logic for sudden load shedding in gas turbine.
