Dynamic Simulation Of Large Wind Turbine Gearbox

Wind turbines work environment becomes increasingly complex, suffered from changeable loads, constitute the possible reasons of failure of wind turbine drive system. This paper studies the wind turbine gearbox vibration characteristics for the wind turbine gearbox provide the basis for the design, the main research contents include:1) The wind turbine gearbox transmission dynamics preliminary study. This article explains the basic theory of dynamic characteristics of wind turbine drive system.2) The establishment of wind turbine driven system model.Use Romax Designer software to establish the virtual model of the two doubly-fed induction generator with 750 kW stall-controlled wind turbine drive system. 3) The wind turbine gearbox simulation analysis. The establishment of wind turbine gearbox vibration characteristics of the model analysis to calculate the system natural frequency and vibration mode to study the changes to the system components, the geometric parameters on the system natural frequency of the impact; in Micon750kW gearbox to change the structure of the sun wheel floating form, study how the structure impact the natural frequency of gearbox system.
