Abstract
Although switched-reluctance machine (SRM) possesses many structural
advantages and application potential, it is rather difficult to successfully control with
high performance being comparable to other machines. Many critical affairs must be
properly treated to obtain the improved operating characteristics. This chapter
presents the basic and key technologies of switched-reluctance machine in motor
and generator operations. The contents in this chapter include: (1) structures and
governing equations of SRM; (2) some commonly used SRM converters; (3) estimation of key parameters and performance evaluation of SRM drive; (4) commutation
scheme, current control scheme, and speed control scheme of SRM drive; (5) some
commonly used front-end converters and their operation controls for SRM drive;
(6) reversible and regenerative braking operation controls for SRM drive; (7) some
tuning issues for SRM drive; (8) operation control and some tuning issues of
switched-reluctance generators; and (9) experimental application exploration for
SRM systems—(a) wind generator and microgrid and (b) EV SRM drive.
Keywords: switched-reluctance machine, motor drive, generator system,
modeling, current control, speed control, commutation shift, voltage boosting
Conclusions
Compared to other machines, SRM is more difficult to control for yielding
satisfactory operating characteristics. This chapter has presented some basic and
key issues for SRM operated as motor and generator. These include structural
features, governing equations and dynamic model, SRM converter, some front-end
DC/DC converters and SMRs, some key motor parameters estimation and experimental performance evaluation of an SRM drive, commutation scheme, dynamic
controls, reversible and regenerative braking operation controls, operation control
and tuning issues of SRM and SRG, etc. Finally, two example SRM plants are
presented to demonstrate the affairs being described, including a wind SRM-based
microgrid and an EV SRM drive.
