摘要
In order to study the response characteristics of the wind turbine drive system gear fault in its electrical signal in the stator theoretically, on the basis of considering the gear mesh stiffness change and simulating the broken gear fault characteristics, building the gear vibration dynamics differential equation and the simulation model. The induction motor model provided by SIMULINK is set as winding generator mode, simulate doubly-fed wind power generator. Connect the speed fluctuations output of the gear vibration model with the speed input of the generator model, construct electrical and mechanical joint simulation model. Through simulation and verification analysis, it shows that the generator electrical signals can accurately reflect the mechanical fault characteristics information of the transmission system.
