ABSTRACT

In today’s energy shortage, and the wind energy utilization in recent years more and more get the attention of people, on the one hand, the utilization rate of wind power, on the other hand is to the attention of the wind motor life. This paper in-depth studies wind turbine hydraulic yaw system, and the different factors affecting the yaw, MW grade wind turbine used in this paper using hydraulic yaw control, and the yaw system is the key of the wind turbine, this paper expounds the structure and hydraulic principle diagram, based on this, expounds the hydraulic yaw control system how to realize the automatic yaw, lateral wind 90 degrees, artificial yaw and automated solutions for cable, and other functions, the system adopts hydraulic system as the main control system, with high stability and reliability. But also can improve the efficiency of wind turbines use wind energy and wind motor service life
