Automatic yaw delay control system of fan

The invention relates to the technical field of fan yaw control, in particular to a fan automatic yaw delay control system which comprises a yaw angle module, a delay control module, a delay control module, a delay control module and a delay control module. The yaw angle module determines the yaw angle of a fan according to wind direction information and fan orientation information; the yaw pressure module is used for correcting preset yaw pressure according to the wind speed information and the yaw angle of the fan; the delay yawing module is used for yawing after a preset delay length during yawing of the fan, correcting the delay length according to the yawing pressure, and starting a yawing motor for yawing according to the corrected delay length; the motor power module is used for controlling the yaw motor to yaw the fan, determining the output power of the yaw motor according to the yaw angle of the fan, and adjusting the output power of the yaw motor according to the wind speed information and the yaw
