Abstract: The present disclosure provides a method and device for simulating a dynamic digital twin model of dominant operation of a wind turbine generator assembly, by which conventional operational parameters of the wind turbine generator assembly that are acquired in real time are preprocessed to obtain steady-state operational parameters of the wind turbine generator assembly. A pneumatic subsystem-related data black box model, a transmission subsystem model, a tower subsystem model, and an electrical subsystem model are simulated individually using the steady-state operational parameters, and then combined to form a dynamic dominant-operation simulation model for simulating an operation process of the wind turbine generator assembly. Meanwhile, a dynamic deviation compensation model is constructed on the basis of the dynamic dominant-operation simulation model.
