The paper demonstrates the possibility of using the asynchronous machine as a generator to supply power to battery power plant for the northern regions of Russia. The work introduces the main advantages of applying induction machines in generating mode to provide power to consumers both three-phase alternating current and direct current through the rectifier devices. The developed control system for asynchronous generator of renewable energy source is introduced. Such system is simple in application, relatively inexpensive, has high speed and allows adjusting parameters of voltage over a wide load range. The asynchronous generator automatic control system was experimentally analyzed. The authors demonstrate the availability of using an automatic voltage regulator with linear capacitors as such system.
