Dynamic Characteristics Analysis and Active Disturbance Rejection Control of Hydrogen Blended Gas Turbine

Under the background of carbon peaking and carbon neutrality, hydrogen blending combustion technology for gas turbines has attracted significant attention. The dynamic characteristics and control strategies of hydrogen-blended gas turbines are crucial for improving combustion efficiency. This paper employs a modular modeling approach to establish a dynamic simulation model for hydrogen-blended gas turbines on a simulation platform. It investigates the dynamic characteristics and control strategies of hydrogen-blended gas turbines, analyzing the trends of key parameters under different operating conditions and hydrogen blending ratios. The control effects of PID and ADRC strategies on hydrogen-blended gas turbines are compared. The results indicate that as the hydrogen blending ratio increases, the fuel flow required to maintain the same operating conditions decreases, while the turbine inlet pressure and exhaust temperature also decrease. At the same time, the emissions of CO 2 and NOx also decrease. Higher blending ratios lead to more pronounced temperature variations. Both ADRC and PID control strategies can maintain the rotor speed and exhaust temperature near the set values, with ADRC achieving better control performance under varying operating conditions.
