  • Simulation of a number of modifications by the prospect of a vortex-type wind power installation using structures of various topologies directing the air flow

    A method for remote determination of the angular velocity of rotation of the blades of a wind generator based on digital processing of the video stream of this wind generator is considered. The main problems that are encountered with this method of measuring angular velocity are analyzed. The considered method for determining the rotation speed of the blades of a wind generator is possible provided that the frame rate is several times greater than the determined rotation frequency. The minimum possible error of this measurement method was found; the real error of measuring the angular velocity was calculated on a specific example.

    Keywords: digital processing of the video stream, image stabilization of the wind generator, finding the contours of the rotor blades, estimation of the angular speed of rotation of the rotor
