Abstract
In the paper, the possibilities of application of switched reluctance generators in modern variable-speed drives were discussed. The process of mechanical energy conversion into electric energy was discussed. Based on simulation and laboratory tests, output power profiles, efficiency profiles and profiles of ratio of output power to phase current were determined in the single-pulse mode. The authors showed that proper selection of control parameters allows the operation of the SRG with maximum power, maximum efficiency or maximum ratio of output power to phase current. Finally, conclusions concerning advantages of using SRGs in variable-speed applications were drawn.
Highlights
Due to the development of variable-speed applications and increasing demand for electrical energy, research on efficient, fault tolerant, compact and reliable generation systems are being conducted
The influence of control parameters on properties of switched reluctance generator was determined based on the simulation model
Points of maximum efficiency was obtained at completely different control angles than points of maximum output power
Summary
Due to the development of variable-speed applications and increasing demand for electrical energy, research on efficient, fault tolerant, compact and reliable generation systems are being conducted. Electric machines, which operate depending on the situation, among others, as a generator, are used in both of these types of drives The development of these types of vehicles is a part of a global tendency to decrease negative impact of combustion engines on the environment. Combustion engine drives electric machine which operates as a generator and charges batteries. In vehicles with electric drive, batteries are charged from the mains In both electric and hybrid drives, part of accumulated kinetic energy of moving vehicle is converted into electric energy. It is possible when electric machine operates as a generator. The rotor tends to the position where reluctance is the smallest
