摘　　要：双馈式风力发电机作为一种利用风力发电的新型装置,结构和运行环境相对复杂,影响因素较多,机组故障率较高。基于此,在对双馈式风力发电机基本组成介绍的基础上,简述了常见齿轮箱结构,接着进行故障部位分析,并以两级行星一级平行轴齿轮结构为研究对象,利用时域分析、频域分析及包络解调等工具进行振动分析,最后得出诊断结论并给出检维修建议。结果表明,该方法可为现场预知性维检修提供有效的指导和帮助,具有一定实用价值。As a new type of wind power generation device,the doubly fed wind turbine has a relatively complex structure and operating environment,with many influencing factors and a high unit failure rate.On the basis of introducing the basic composition of doubly fed wind turbines,this article first briefly describes the common gearbox structures,then analyzes the fault location.Then,taking the two-stage planetary parallel shaft gear structure as an example,vibration analysis is conducted using tools such as time-domain analysis,frequency-domain analysis,and envelope demodulation.Finally,diagnostic conclusions are drawn and maintenance suggestions are given.The results indicate that this method can provide effective guidance and assistance for on-site predictive maintenance,and has certain practical value.
