风力发电机在线振动监测系统的设计
摘要：随着清洁能源的日益增长，风力发电行业出现了飞速的发展，与此同时，风力发电生产也面临着更多的挑战，风场业主与运行人员必须找到更智能化的运行方式，能够通过控制运行和维护成本来提高风力发电的盈利能力。风机在线振动监测系统可以帮助用户准确的监测到风机传动系统的早期故障。可以在故障发生早期，快速确定故障位置和原因，通过塔上的维护解决故障，从而节省吊装的费用，并且可以为检修安排和备件采购预留充足的时间，还可以避免引发二次故障以及恶性事故的发生。提高风机利用率，从基于时间或故障的检修方式变为基于风机健康状态的检修方式，预知性的检修规划能帮助优化检修的间隔，并延长风机或部件的使用寿命，从而提高机组的可利用性。

Abstrt:With growing clean energy,wind power industy in the rapid development,at the same time,wind power production is faced with more challenges,wind field owners and operators have to find more intelligent operation mode,to control the operation and maintenance cost to increase the profitability of wind power.The fan online vibration monitoring system can help users accurately monitor the early failure of the fan transmission system.Can,in the early failure quickly to identify the cause of the fault location and,through the tower maintenance to solve fault,thus saving the cost of the hoisting,and may arrange for maintenance and spare parts purchasing set aside enough time,can avoid to cause secondary fault and malignant accidents.Improve the utilization rate of the fan from maintenance method based on time or failure to fan health maintenance method,based on unexpected overhaul pianning can help to optimize maintenance intervals,and extend the service life of fan or components, thus improve the service life of fan or components,thus improve the availability of the unit.
