摘要
掺氢燃气轮机是氢电耦合的新型能源转化装备,建立掺氢燃气轮机的动态模型,对深入理解燃气轮机掺氢特性以及精准调节掺氢控制参数具有重要意义。针对掺氢燃气轮机的特点,采用机理建模方法建立了压气机、混合燃料燃烧室、透平等燃气轮机部件模型,基于迁移学习方法构建了掺氢燃烧效率等燃气轮机部件特性模型,通过耦合形成掺氢燃气轮机热力学动态模型,并以某小F掺氢燃气轮机现场运行和试验数据进行模型的稳态和动态验证。结果表明:所建模型不仅可用于天然气掺氢燃料的燃气轮机仿真,还可用于掺氢比动态调节时的升降负荷仿真,能够为燃气轮机掺氢比控制策略研究提供精确的仿真模型。
Hydrogen-blended gas turbines represent an innovative energy conversion technology integrating hydrogen with electricity.Developing a dynamic model for these turbines is crucial for understanding hydrogen blending characteristics and precisely adjusting control parameters.Based on mechanism modeling method,detailed component models for the compressor,combustion chamber(for hydrogen and natural gas mixtures),and turbine were established.Using transfer learning methods,models for hydrogen-blended combustion efficiency and other gas turbine component characteristics were developed,which were then integrated to form a thermodynamic dynamic model of hydrogen-blended gas turbines.The model's steady-state and dynamic validation was conducted using on-site operation and test data of a small F-class hydrogen-blended gas turbine.The results demonstrate that the constructed model is not only applicable for simulating gas turbines using hydrogen-blended natural gas fuel,but also for simulating load increase and decrease during dynamic hydrogen blending ratio adjustments.It can provide an accurate simulation model for research on hydrogen blending ratio control strategies for gas turbines.
