| 摘 要： | 随着人类对能源的大量需求,电力行业飞速发展,风力发电以其投资成本低,机组结构简单,绿色环保,已经逐渐成为清洁能源的发展趋势,而风电场建成后的运行维护成本直接决定着风电场的效益,因此,对风电机组的典型故障进行分析,建好机组健康管理档案就显得非常重要.在对风电机组传动系统的组成和各部分的功能及风电机组的主要传动部件的故障机理及故障类型分析的基础上,以某风电场实际发生的弹性支承螺栓断裂及联轴器损坏故障为研究对象,应用小波变换进行故障的诊断和定位,分析故障产生的成因、发展过程及趋势.以新西兰况得实公司的风电机组振动检测仪器及自带分析软件对小波变换分析结果进行了验证,结果与实际状况非常吻合.据此提出了今后避免此类故障发生的预防措施和改进方法,以期为今后风电场的运营维护提供可靠的技术支持.
