Abstract：Yaw system control strategy directly determines the economic benefits of wind power system. According to the operational principle, yaw system control strategy is divided into reboot tracing wind strategy and implement tracing wind strategy, and research status is reviewed separately. Analysis results show that current research hotspot is implement tracing wind strategy of yaw system, but new research on the reboot tracing wind strategy of the yaw system is less. Based on quantitative analysis results of yaw system real operation data, field wind source data and power curve of wind turbine, this paper points out that the traditional reboot tracing strategy of yaw system has the defect of the more lifetime of yaw system consumed in low wind speed segment, and influences comprehensive benefit of yaw system life cycle; formulating yaw system reboot wind tracing strategy should comprehensive consider wind farm wind source characteristics and wind turbine power generation characteristic, and there is great value that carried out new reboot wind tracing strategy to realize the efficient utilization of the yaw system operation life and should be concerned.
