The invention provides a yaw control system of a wind turbine, and the control system comprises: an overvoltage protection part which is used for measuring the temperature generated by the overvoltage of a generator, comparing the temperature with a preset temperature, and outputting a protection signal for stopping operation corresponding to the comparison results; an overspeed protection which is used for measuring a rotating speed generated by the overspeed of the generator; a wind velocity protection part which is used for comparing a wind velocity measured by an anemograph with a preset condition value of protection operation, and outputting a protection signal for yaw protection corresponding to the comparison results; and a yaw control part which is used for controlling the yaw according to the selected input of a user when the protection signals outputted by the overvoltage protection part, the overspeed protection and the wind velocity protection part set the mode of protection action or remove the protection action. The system provided by the invention can randomly set the mode of yaw control of the wind turbine according to the requirements of the user, controls the output through a mode of automatic operation of external protective factors, and improves the output efficiency of the wind turbine. |
