Research on failure and prevention of wind turbine gearbox

Wind power generation is in a period of rapid development due to its mature technology and environmental friendliness. Wind turbine is the main equipment for wind power generation, and the performance of its gearbox determines the stability and economy of power generation. This paper introduces the changes of installed capacity in various stages of wind power generation in the world, analyzes the common failure forms of wind turbine gearboxes, and on this basis, studies the failure parts and main causes, and further puts forward preventive measures for the failure forms of gearboxes, which can provide reference for wind farm personnel to carry out maintenance of wind turbines
