风力发电机组振动监测技术应用与实践

Application and Practice of Vibration Monitoring Technology for Wind Turbine

当前,风力发电已成为世界新能源发电中发展最迅速的行业,我国风电总装机容量已跃居世界第一。但由于缺乏关键技术,盲目扩大风电场建设,加之环境恶劣,国产风电机组故障发生率明显高于国外,这不仅增加了风力发电机组维修费用,也大大降低了发电可靠性。开展风电机组的运行状态监测,可以提前发现设备运行隐患,实现风力发电机设备的计划检修,是降低生产维修成本、防止重大事故发生的有效措施。

At present, wind power has become the world＇ s most rapid development of new energy power industry, China＇ s total installed capacity of wind power has been ranked first in the world. But because of the lack of key technologies, blindly expand wind farm construction, coupled with the harsh environment, failure of domestic wind turbine was significantly higher than that in foreign countries, which not only increases the wind turbine maintenance cost, but also greatly reduce the reliability of power generation. To carry out the operation condition monitoring of the wind turbine, it can find the hidden trouble of equipment operation in advance, and realize the plan maintenance of the wind turbine generator equipment. It is an effective measure to reduce the cost of production and maintenance and prevent the occurrence of major accidents.
