Design of converter topology for switched reluctance wind power generator

Abstract

Residential electricity load decomposition method based on maximum a posteriori probability AIP Conference Proceedings 1839, 020042 (2017) Abstract. Considering the small output power of switched reluctance generator (SRG) at low speed, this paper proposes a new power converter topology based on the operation principle of switched reluctance generator, aiming to improve the performance of traditional power converter. The new power converter includes two working modes: full winding excitation power generation and partial winding excitation power generation, which are applied to different speed to increase the output power. To verify the feasibility of proposed converter, simulations and experiments on the SRG with single phase, external rotor, and U-shaped stators are conducted, compared with the traditional power converter. The simulation results show that the new power converter increases the output power and improve the efficiency of SRG at low speed.

A Comprehensive Analysis and Review on Electrical Machines in Wind Energy Conversion Systems

“…In the SRG, when the number of turns of the stator winding is too low, this will reduce the use of the generator and reduce the efficiency of power generation. For this purpose, a new power converter for SRG has been proposed to solve the problem of low-power output at low-speed [57]. This converter is similar to the traditional asymmetrical bridge used by several authors in the literature.…”

Analysis of Skewing Effects on Radial Force for Different Topologies of Switched Reluctance Machines: 6/4 SRM, 8/6 SRM, and 12/8 SRM

“…In industrial applications, the Switched Reluctance Machine (SRM) has attracted much interest. It is a good candidate for electric or hybrid vehicles (Cheng et al 2019), (Fathabadi 2018), and (Martinez et al 2016), electrical energy production (Bahy et al 2020), (Chen et al 2020), and (Dong et al 2017), aeronautics (Bartolo et al 2016) and flywheel energy storage systems (Cárdenas s et al 2006). SRMs have several advantages, such as robust construction without windings or magnets on the rotor, high reliability, low manufacturing cost, high torque, insensitivity to high temperatures, and fault tolerance (Dias et al 2020), (dos Santos Barros et al 2017), (Sarr et al 2020), and (Lu et al 2020).…”

Model predictive control of switched reluctance generator based onZ‐source converterfor wind power applications

“…To solve the problem, the c‐shape stator cores in modular design were employed in Reference 19 and a ring‐shape excitation assistant coil was placed between the stator coils. In order to overcome the same problem of high inductance during excitation mode, partial winding excitation was performed by a new converter in Reference 20. In References 19 and 20, special design of the generator is needed and the idea is not applicable for the existing generators.…”

In References 19 and 20, special design of the generator is needed and the idea is not applicable for the existing generators. In Reference 21, generation voltage was regulated by utilizing a buck‐boost circuit between the dc power supply and machine generation circuit.…”
