Electromechanic Energy Storage. Development and Research Investigation

Accumulation technologies of electric energy in electric power supply are an effective tool for increasing energy efficiency and energy saving. This paper is devoted to the development of electromechanic energy storage. Theoretical and experimental results of the development of electrokinetic energy storage are presented; they are intended for the wide application in local electrical networks. The design of the electrokinetic energy store based on the magnetic levitation of the rotor-flywheel with the use of superconducting elements is described; the mathematical modeling of the stiffness of the contactless suspension of the rotor-flywheel is performed. The technical characteristics of electromechanic energy storage and its scope of application are given.
