为了掌握滑动式偏航系统的运行特性,揭示风机偏航系统故障的原因,设计了一套基于LabVIEW的风机偏航数据采集系统,并对某风电厂的偏航系统进行长达3个月的在线监测,通过数据分析发现偏航系统运行中的一些问题,如:4个电机功率不一致,差值较大,并均存在波动;在偏航过程中,偏航系统的振动比较平缓,但存在突然增大的状况.根据分析,给出了偏航系统运行的建议,从而可以大幅减少偏航系统故障的出现,提高电厂效益.

For mastering the operation characteristics of the sliding yaw system and looking for the fault reasons of the fan sliding yaw system,a set data acquisition system of fan yaw based on LabVIEW was designed,and the yaw system in a wind power plant was conducted with on-line monitoring for 3 months. Some problems in operation of the yaw system are discovered by data analysis,such as the different power,large power difference value and power fluctuation of the four motors,and in the yaw process,the vibration of the yaw system is gentle,and the situation of sudden increscent vibration is existed. According to the analysis,the operation suggestions of the yaw system are provided,which can reduce the fault occurrence of the yaw system significantly,and improve the efficiency of the power plant.
