Petrenko A. Wind power system with combined electricity supply and water pumping on the basis of the permanent magnet electric linear generator of back-and-forth motion.

The dissertation deals with increasing power efficiency of windpump by means of working out wind power system with combined electricity supply and water pumping on the basis of the permanent magnet electric linear generator with changes of modes of electricity supply and water pumping, and also stochastic receipt of wind power. The scientific idea of the thesis consists in combined use of mechanical energy of a wind turbine with back-and-forth motion for the pump equipment drive and the permanent magnet electric linear generator drive, and also for the coordination of combined electricity supply and water pumping processes. Principles of construction of wind power system with combined electricity supply and water pumping are formulated. Mathematical and imitating models for researching of electromagnetic and electromechanical processes in electrotechnical system on the basis of the permanent magnet electric linear generator of back-and-forth motion are developed. Operating modes of wind power system are coordinated with combined electricity supply and water pumping, and also stochastic receipt of wind power.
