摘要

Factors such as the atmospheric environment or component performance influence various matching relationships as well as maximum output power in triaxial gas turbines with variable power turbine guide vanes. This paper proposes a control strategy called High Power Mode (HPM) which solves the matching problem, adjusts fuel flow, adjusts the guide vane to adapt the gas turbine to unpredictable factors automatically, and enhances its maximum output power without exceeding high- and low-pressure rotor rotational speeds or combustor outlet total temperature limits.We first built a component-level gas turbine simulation model to explore the control strategy and the influence of guide vane angle on gas turbine working for the variable geometry triaxial gas turbine. We conducted a series of gas turbine rig tests to validate the simulation model. We then determined the guide vane angle effect law on the gas turbine performance based on the simulations as well as experimental data. HPM, including guide vane angle and fuel flow rate control strategies, was established according to the acquired guide vane angle influence law. We wrote an HPM control program in MATIAB/SIMULINK to find that the program indeed optimizes components and parameters (high- and low-pressure rotor rotational speeds and combustor outlet total temperature) while matching them effectively within unpredictable environments. The maximum gas turbine output power can be increased with the program by more than 4% in certain atmospheric environments. (C) 2019 Elsevier Masson SAS. All rights reserved.
