Abstract: 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.
