The embodiment of the invention discloses a fan yaw correction system, and relates to the technical field of wind power generation in order to solve the problem that no anticipation mechanism for theyaw angle error condition exists in the prior art. The fan yaw correction system comprises a controller, a correction cam counter and an electronic switching value sensor. The electronic switching value sensor is used for testing the real-time yaw angle. The controller is connected with the electronic switching value sensor and used for obtaining a first test result of the electronic switching value sensor and determining a first test value of the cable torsion angle according to the first test result. The correction cam counter is used for judging whether the cable torsion angle reaches a preset angle or not, and the preset angle is smaller than the cable torsion limit angle. When the cable torsion angle reaches the preset angle, the controller receives an angle reaching signal sent by the correction cam counter and judges whether a first difference between the first test value of the cable torsion angle and the preset angle exceeds a first preset difference or not, and if yes, cablecombing is conducted to the zero degree with the preset angle as the cable combing angle, and the yaw angle is reset.

The embodiment of the invention discloses a fan yaw correction system, and relates to the technical field of wind power generation. The fan yaw correction system is used for solving the problem that the prior art lacks of a pre-judgment mechanism for the yaw angle error condition. The fan yaw correction system comprises a controller, a cam counter and an electronic switching value sensor. The electronic switching value sensor is used for testing the real-time yaw angle. The controller is connected with the electronic switching value sensor and used for acquiring the first testing result of theelectronic switching value sensor. The cam counter comprises a slide rheostat, and the yaw angle is measured through the slide rheostat. The controller is connected with the slide rheostat and used for acquiring the second testing result of the slide rheostat and calculating the first difference between the first testing value and the second testing value. When the first difference exceeds a first preset difference, an alarm is started so as to inform a worker that the yaw angle error is large.
