Eddy currents in a passive magnetic axial thrust bearing for a flywheel energy storage system
Two types of passive magnetic lift bearings were evaluated in terms of thrust force and eddy current losses. The first type of bearings were based on two sets of segmented Halbach arrays mounted in repulsive mode, and the second type was based on ring-magnets. The eddy-currents studied arose in the bearing due to manufacturing variations of magnetic remanence, and due to non-radial magnetizatio...
متن کاملFlywheel 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 کاملA Control Strategy for Flywheel Energy Storage System for Frequency Stability Improvement in Islanded Microgrid
The Micro-Grid (MG) stability is a significant issue that must be maintained in all operational modes. Usually, two control strategies can be applied to MG; V/f control and PQ control strategies. MGs with V/f control strategy should have some Distributed Generators (DGs) which have fast responses versus load changes. The Flywheel Energy Storage System (FESS) has this characteristic. The FESS, w...
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 ...
