    • The invention relates to numerical gas turbine models. The object of the present invention is to propose a gas turbine model and a method for the modeling of a gas turbine, which permits transient modeling with high precision and at the same time numerically efficient means for modeling a gas turbine. The present invention is based on a gas turbine model, which consists of a plurality of sub models (34). These sub models are either purely dynamic or static, which allows significant simplifications in the numerical solution of the overall model. System parts, which simulate the effects of volumes, metal masses, of actuators, and of measuring systems are regarded as dynamic. The remaining system parts are regarded as static over a time characteristic.
    • 本发明涉及数值燃气轮机模型。 本发明的目的是提出一种用于燃气轮机建模的燃气轮机模型和方法,其允许高精度的瞬时建模,并且同时具有用于对燃气轮机进行建模的数字有效的装置。 本发明基于由多个子模型(34)组成的燃气轮机模型。 这些子模型是纯动态或静态的,这允许在整个模型的数值解中显着简化。 模拟体积,金属质量,执行器和测量系统的影响的系统部件被认为是动态的。 剩余的系统部件在时间特性上被视为静态的。

    • A system (S) for controlling nitrogen oxide (NOx) emissions and combustion pulsation levels of a gas turbine having a gas turbine combustion system comprising a single combustion chamber and multiple burners. The system (S) comprises a cascade structure having a first and second control level (1, 2), the first (1) comprising means to control NOx emissions and generate combustion pulsation target levels based on the difference between measured and target NOx emission levels, and the second (2) comprising means to control pulsation levels and generate a ratio (γ) of fuel flow to different types of burners or to different stages of each burner. The fuel flow ratio (γ) is based on the difference between the measured and generated target pulsation levels. The control system (S) enables the operation of a gas turbine to meet NOx emission requirements, while maintaining combustion pulsation levels within limits that ensure improved lifetime of the combustion system.
    • 一种用于控制具有包括单个燃烧室和多个燃烧器的燃气轮机燃烧系统的燃气轮机的氮氧化物(NOx)排放和燃烧脉动水平的系统(S)。 系统(S)包括具有第一和第二控制水平(1,2)的级联结构,第一(1)包括控制NOx排放并基于测量和目标NOx排放水平之间的差异产生燃烧脉动目标水平的装置 ,并且第二(2)包括控制脉动水平并产生燃料流到不同类型燃烧器或每个燃烧器的不同级的比率(α)的装置。 燃料流量比(α)基于测量和产生的目标脉动水平之间的差异。 控制系统(S)使得燃气轮机的操作能够满足NOx排放要求,同时将燃烧脉动水平保持在限制范围内,以确保燃烧系统的寿命提高。
