Development of a kinetic electric energy drive with magnetic compensation

Abstract

The optimal parameters of a compact kinetic energy storage device are considered, which allow to cover the widest range of consumers of autonomous solar power plants. Estimated consumer market volumes. A comparative characteristic of various types of electrical energy storage devices is carried out. The advantages and disadvantages of each of the existing types of drives are indicated. The cost characteristic of one charge-discharge cycle of electrochemical storage devices is given. The combined use of kinetic and electric energy storage devices in the structure of a hybrid storage device is shown with the aim of optimizing the cost of generating electric energy from alternative sources of electric energy. In this case, the compensation of high-frequency voltage ripples is carried out due to the energy previously stored in the kinetic storage device. Technical problems arising when using kinetic energy storage devices (flywheels) are considered. These include the presence of a gyroscopic effect that does not allow mobile performance of the drive, as well as special requirements for the material from which the flywheel is made. Possible features of the design of flywheel-based drives are considered. The use of magnetic compensation of the centrifugal forces of the flywheel eliminates the use of high-strength and expensive materials.
