The work of an autonomous contra-rotating vertical axis wind turbine (VAWT), which uses a special device, i.e. a rotary transformer, has been examined in the article. The latter performs two functions: contactless transmission of generated electric energy from the moving armature of synchronous generator with permanent magnets and automatic control of VAWT electrical load. To construct the quasi-optimal control system, the estimator of average wind speed, which covers two wind rotors, was developed. Computer simulation was carrying out on a test wind profile taking into account parameter differences and work conditions of two wind rotors. The results showed satisfactory efficiency of VAWT work at such conditions.
