The invention discloses a wind power generation yaw adjusting system which comprises a wind power generator cabin and an adjusting bottom plate arranged in the wind power generator cabin. A servo motor is arranged on the adjusting bottom plate. The output end of the servo motor is sequentially and fixedly sleeved with an active wheel and an active driving wheel from top to bottom. A driven rotary shaft is further arranged on the adjusting bottom plate. A box body is arranged in the wind power generator cabin. A servo driver and a temperature sensor are arranged in the box body. A wind transducer is arranged on the outer side surface of the wind power generator cabin. The servo driver is electrically connected with the servo motor, a limiting output motor and the wind transducer. A temperature displayer is arranged on the outer side of a wind power generator. The temperature displayer is electrically connected with the wind transducer. The wind power generation yaw adjusting system has the beneficial effects that through the inner-outer dual-engagement structure, accuracy of the rotation angle of a wind wheel of the wind power generator is guaranteed, two gears work simultaneously and share the loads of large torque, and the service life is long.
Description
technical field [0001] The invention relates to the field of new energy equipment, in particular to a wind power generation yaw adjustment system. Background technique [0002] As a clean energy source, wind power generators have been widely used at present. At present, there are mainly the following types of large-scale commercial wind power generators: double-fed variable speed constant frequency wind power generators, semi-direct drive variable speed constant frequency generators and direct drive variable speed constant frequency generators . These wind turbines use an electric yaw system to adjust the rotor and align it with the wind. The yaw system generally includes a wind vane that senses the wind direction, a yaw motor, a yaw planetary gear reducer, a large gear of the gyratory body, etc. Its working principle is as follows: the wind vane, as a sensing element, transmits the electrical signal of the change of wind direction to the processor of the control loop of t...
