Description

technical field [0001] The invention relates to a wind power generation simulation device, in particular to a test device and method which has wind shear and tower shadow effects and is used for simulating the wind power generation process under real working conditions. Background technique [0002] Wind turbines are generally installed in remote areas with good wind energy resources such as Gobi, wilderness, and high mountains, and the operating environment is relatively harsh. As the core component of wind turbines, wind power gearboxes operate under severe alternating load conditions for a long time. In addition, the temperature difference between day and night in remote areas, the impact of wind and sand, the manufacturing and assembly errors of wind power gearboxes, as well as their own wear and poor lubrication will all cause damage to wind power gearbox components. Once the equipment is shut down due to failure, not only the maintenance is difficult and the maintenan...

AI Technical Summary

Problems solved by technology

[0003] The traditional wind power gearbox test bench is only used for product research and development, delivery, and finalization of the test device, and often can only conduct some basic tests on wind power gearboxes; while natural wind has strong uncertainties, and the on-site wind power gearbox The harsh environment makes it difficult to effectively and controllably reproduce the operating conditions of wind power gearboxes

In addition, limited by the test environment and test cost of the full-power wind power gearbox, it is impossible to effectively simulate the transient characteristics and steady-state characteristics of wind power generation in the laboratory environment
