The object of research is a small controlled sail wind power station (SWPS) with a sail in the form of umbrella, that is intended for use in wide areas with an average wind speed of 3 m/s. The research aims to increase the efficiency of converting wind energy by choosing the structure and the main parameters of manipulator-converter’s (MC) actuators. The paper contains an analysis of the state of art in the field of wind energy. The main disadvantages of wind turbines in comparison with the SWPS are pointed out in order to outline design requirements. The structure of the MC’s actuator is presented by combination of semi-active spring-damper suspension (SDS), power take-off system (PTS), and electric generator. The research and selection of the semi-active SDS’s parameters of the actuator are carried out by an analysis of the created dynamic model. At the same time, experimental investigations of the dynamic characteristics of the air mass’s motion were carried out beforehand. Calculations of energy balance showed that the results of the proposed modifications made possible to create a SWPS that can operate at rated power at wind speeds of more than 2.5 m/s, regardless of changes in wind speed and direction.
