Analysis of Maximizing the Power Output of Switched Reluctance Generator Using Different Core Materials

Abstract

Switched reluctance generator (SRG) has become the key focus of research for its usage in wind power generation. The sizing and performance of SRG depend on the core material used for the stator and rotor. This paper analyses the impact of the magnetic loading of different core materials on the performance of SRG in terms of self-inductance, torque, iron losses, ohmic losses, and generated voltage. 1 kW SRG with different pole configuration 8/6 SRG and 12/8 SRG for the wind speed of 3 m/s to 6 m/s has been designed. Static and dynamic analyses using the finite element analysis (FEA) were carried out for analytically designed 1 kW SRG with different core materials with the same lamination thickness. Prototypes of 8/6 SRG and 12/8 SRG are fabricated. The output of simulation results has been validated by experimental measurements.

Improvement of Fault Ride-Through Capability of Grid Connected Wind Turbine Based on a Switched Reluctance Generator Using a Dynamic Voltage Restorer

“…The stator of the SRG is comprised of a salient pole with a laminated core and concentrated windings. In addition, the rotor has a salient pole construction independent of windings or permanent magnets, resulting in cost savings and supply chain security, which are two important advantages [4,22]. There are many configurations for SRG.…”

“…It has been discovered that using various core materials and maintaining a constant power output, SRG's power density rose as flux density increased. Static, transient, and thermal analyses have been used to compare the performance of SRG employing different core materials in terms of inductance, produced voltage, iron loss, ohmic loss, and torque while maintaining constant dimensions [22].…”

Performance Enhancement of High Speed Interior Permanent Magnet Synchronous Motors Using Superior Magnetic Material

“…Several studies have identified alloy of iron-cobalt-vanadium as a potential candidate to increase the specific power of synchronous reluctance machines (SRM) [15] and permanent magnet synchronous machines [16] for high-speed and aircraft applications. In wind power generator application, Ramkumar and Latha [17] have presented that the power density of switched reluctance generator (SRG) increased with an increase in flux density (Bm), using different core materials and concluded that to develop an SRG with higher efficiency, reduced losses, increased power density, and torque material selection is crucial. M. E. Abdollahi et al presented the design of a high-density SRM for an aerospace application and proposed a multi-objective optimization framework for the design of a high-power density SRM [18].…”
