In order to study a method of diagnosing wind turbine gear fault by generator electrical signal and extend its field of application. A typical doubly-fed wind turbine is taken as object. The gear pair dynamics model and the mathematical model of generator unit are established on the basis of considering the gear mesh stiffness changes and broken gear fault characteristics. The model of doubly-fed generator and its control system are also built. These two models are interrelated through rotational speed parameter of gear pair and generator. Electrical and mechanical joint simulation model is set, which simulates current of stator at normal and fault state. Current fault characteristics are analyzed when the gear is normal or have a tooth broke in theory. A set of simulation test bench are established, wind turbine gear fault simulation experiment is operated. Collected current and voltage signals from the experiment are compared with rotate speed signal, which can verify the feasibility of the stator current method. Simulation results are compared with fault test simulation.
