The conditions that the manual simulation subunit 121, the hardware-in-loop simulation subunit 125, and the automatic simulation subunit 123 are activated are both "enabled" and "simulation code".
In an embodiment, before step S200, the method further includes the steps of: acquiring a master control system input signal of associated equipment in the wind generating set; and establishing the signal simulation unit according to the input signal of the master control system. That is, before starting, the system establishes a simulation model in the signal simulation unit 120 according to the physical characteristics of the input signals of the main control system of each associated device in the wind turbine generator system.
