<p>An angle displacement measuring method for a pitch system of a wind generator is disclosed in the present invention. According to the present invention, the angle displacement measuring method for a pitch system of a wind generator is comprised by using a laser sensor for detecting a rotational speed and a rotational angle of a hub bearing gear installed in the pitch system of the wind generator. Therefore, the present invention can precisely determine a response feature for the pitch system of the wind generator.</p> |
