Flywheel Energy Storage System with Homopolar Electrodynamic Magnetic Bearing*
.Abstract – The goal of this research was to evaluate the potential of homopolar electrodynamic magnetic bearings for flywheel energy storage systems (FESSs). The primary target was a FESS for Low Earth Orbit (LEO) satellites, however, the design can also be easily adapted for Earth-based applications. The main advantages of Homopolar Electrodynamic Bearings compared to more conventional Active...
متن کاملFlywheel Energy Storage System Based on Boost DC-AC Converter
To extend the operating speed range of a conventional configuration of FESS (flywheel energy storage system), an additional DC-DC boost converter is required between the machine and grid side converters to regulate the output voltage. This paper presents a new FESS based on three-phase boost inverter topology. The proposed system facilitates voltage boost capability directly in a single-stage. ...
متن کاملDesign, Modeling and Control of Magnetic Bearings for a Ring-Type Flywheel Energy Storage System
This study is concerned with the magnetic force models of magnetic bearing in a flywheel energy storage system (FESS). The magnetic bearing is of hybrid type, with axial passive magnetic bearing (PMB) and radial hybrid magnetic bearing (HMB). For the PMB, a pair of ring-type Halbach arrays of permanent magnets are arranged vertically to support the rotor weight. For the HMB, a set of ring-type ...
متن کاملDevelopment of a Passive Magnetic Bearing System for a Flywheel Energy Storage
Magnetic bearings are an attractive alternative to mechanical bearings in flywheel energy storage systems since they greatly reduce friction and wear. However, new problems are introduced in terms of stabilization; particularly the magnetic bearing must provide enough damping to reduce excessive vibrations. Two novel configurations of passive magnetic bearings are introduced to meet system requ...
متن کاملFrequency Regulation of AUT Microgrid Using Modified Fuzzy PI Controller for Flywheel Energy Storage System
Usage of flywheel energy storage system (FESS) is a common method for frequency regulation due to its high power injection capacity and long life time. FESS is equipped by two back-to-back inverters including grid-side inverter and machine-side inverter. In conventional method, the machine-side inverter sets the active power and machine flux while grid-side inverter sets the reactive power and ...
