Gas generator set model suitable for whole-process dynamic simulation

The invention discloses a gas generator set model suitable for whole-process dynamic simulation, and the model comprises a speed regulator model which is used for inputting a fuel valve instruction to an execution mechanism model, and the execution mechanism model is used for obtaining the opening degree of a fuel valve according to the fuel valve instruction, and outputting the opening degree to a prime mover model. Wherein the speed regulator model comprises normal operation control and island mode control, the normal operation control is composed of primary frequency modulation control, main ring control, temperature control and IGV low limit control, and the primary frequency modulation control module comprises multiple frequency modulation modes corresponding to different manufacturer models. The primary frequency modulation control is used for outputting a power instruction and a feed-forward quantity to the main loop control, and the main loop control is used for generating a main loop control instruct
