Method for measuring rotating speed of impeller of wind generating set and related equipment thereof

The invention relates to the technical field of wind power generation, in particular to a wind generating set impeller rotating speed measuring method and related equipment thereof, and the method comprises the steps: building a rectangular coordinate system based on a preset standard; acquiring a horizontal offset and a vertical offset based on the rectangular coordinate system; obtaining a target angular velocity and a target acceleration; based on the target angular velocity, the horizontal offset and the vertical offset, centripetal acceleration is obtained; obtaining an impeller azimuth angle based on the centripetal acceleration, and mapping the impeller azimuth angle to a target interval; obtaining angular acceleration based on the impeller azimuth angle and the target acceleration; and based on the angular acceleration, after the target angular velocity and the impeller azimuth angle are filtered, the target impeller rotating speed is obtained. According to the invention, the accuracy of the impeller
