The aim of the paper is to analyze and optimize the operational safety and efficiency of wind energy conversion equipment. A wind energy conversion device equipped with one oscillating flat blade has been developed and studied. In this device, lateral surface of the blade is firmly attached to the crank, which is kinematically connected with the generator’s slider moving inside the electric coil. As a result, electrical energy is produced in the linear generator. The considered electromechanical device is described by the second order differential equation. In this equation, the interaction of wind flow and relative motion of the blade is described by the approximate relationships of classical mechanics. Operation of the system due to the action of air flow is simulated with computer program Mathcad. Possibilities to obtain energy with generators of different characteristics, the operation of which is regulated by mechatronic control, have been studied. The effect of a constant wind flow with a constant speed and also with a harmonic or poly harmonic component is considered. Partial parametric optimization of the electromechanical system has been performed. Graphs for the change of plate phase coordinates, as well as for the change of the obtained power are presented. The results obtained in the paper can be used in the study of similar fluid flow interactions at damping or energy extraction.
