In order to decrease the impact on the environment, a lot of wind turbine generation systems have been actively introduced all over the world. The importance of the Yaw control system of large wind turbines rises in this situation. The investigation and analysis for the large wind power system with trail torque mechanism, THK-R Guide and Gearless structure, the application and possible result for the Trail Control Installation and R-Guide in the large wind power system.
