The invention discloses a wind-driven power generator yaw control method and module and a control device based on the control module, relates to the wind-driven power generator yaw control technology, and aims to solve the problem that the instantaneous wind direction interferes yaw control to allow a yaw unit to be started frequently, and unstable current output, difficulty in control and cabin service life lowering are caused. If wind speed exceeds a set value range or the deviation angle of the wind direction and a cabin is not larger than 16 degrees, the yaw unit keeps the state; if the deviation angle ranges between 16 degrees and 180 degrees, a yaw motor rotates reversely, or else the yaw motor rotates forwardly, and wind-driven power generator yaw control is achieved. The wind-driven power generator yaw control module is embedded into the control device based on the module. The yaw unit has a delay starting function and adopts error control, interference caused by the instantaneous wind speed is prevented, wind energy utilization rate is guaranteed, the situations of frequent starting and control difficulty caused by zero alignment are avoided, and cabin service life can be prolonged. The control method and module and the control device are applicable to wind-driven power generator yaw control.
