Simulation method and device of gas turbine, and storage medium

The invention discloses a simulation method and device of a gas turbine, and a storage medium, and relates to the field of gas turbines, for reducing the cycle and cost of a gas turbine performance optimization experiment and improving the experiment safety. The simulation method comprises the following steps: obtaining input parameters set for each part model of a gas turbine, wherein each part model is a preset model for simulating the operation process of the corresponding part of the gas turbine, and characteristic parameters for realizing the characteristic operation of the part model arearranged in each part model; inputting the obtained input parameters into the corresponding part models respectively to perform operation by combining the characteristic parameters in the corresponding part models to obtain a first simulation result of the operation process of the gas turbine; and determining whether the simulation result matches an expected result or not, and if so, determiningthat the characteristic pa
