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.
