Abstract:

Advanced high-power gas turbine is the main research and development direction of future ship power. Three-shaft intercooled-cycle gas turbine engines as the prime mover for marine integrated electric propulsion system have been extensively used in the Chinese navy, and their dynamic performance has attracted many investigators’ attention. This paper extends current research on further improving three-shaft intercooled-cycle gas turbine engine operational performance. Firstly, on the basis of Matlab/Simulink software platform, a nonlinear three-shaft intercooled-cycle gas turbine engine thermodynamic model is set up to simulate the engine dynamic performance. Its power/free turbine shaft speed should be kept constant so as to obtain good dynamic performance control quality for the engine generation set. Under transient loading or unloading operating mode, the power/free turbine shaft speed easily deviates from the nominal value due to operational requirements of increasing or reducing power. In view of the phenomenon that the power turbine is prone to overspeed during the sudden load shedding process, the control strategy of the intercooled-cycle gas turbine power generation module is studied. A dual-mode switching control using fuzzy adaptive PID controller and PI controller and a joint control scheme of high-pressure compressor blow-off controlling are proposed. This provides a control strategy for the actual use of the marine intercooled-cycle three-shaft gas turbine integrated electric propulsion system in the future.
