This paper presents the application of an adaptive control strategy to enhance the low voltage ride through (LVRT) capability of a grid-connected switched reluctance wind generator. In this study, the switched reluctance generator (SRG) is driven by a variable-speed wind turbine and connected to the grid through an asymmetric half bridge inverter, DC-link, and DC-AC inverter system. The adaptive proportional-integral (PI) controllers are used to control the power electronic circuits. The Widrow-Hoff adaptation algorithm is used in this study. The Widrow-Hoff delta rule can be used to adapt the PI controllers' parameters. The detailed modelling and control strategies of the overall system are presented. The effectiveness of the proposed control scheme is verified under a severe symmetrical grid fault condition. The validity of the proposed system is verified by the simulation results, which are carried out using PSCAD/EMTDC. 0

This paper presents the application of an adaptive neuro-fuzzy controller (ANFC) for speed control of the switched reluctance generator (SRG). In this study, the SRG is driven by a variable-speed wind turbine and connected to the grid through an asymmetric half bridge inverter, DC-link, and DC-AC inverter system. Speed control plays an important role in variable-speed operation of the SRG to ensure maximum power delivery to the grid for any particular wind speed. The effectiveness of the proposed ANFC is compared with that of the conventional proportional-Integral (PI) controller. Detailed modeling and control strategies of the overall system are also presented. The validity of the proposed system is verified by the simulation results using the real wind speed data measured at Hokkaido Island, Japan. The dynamic simulation study is performed using the laboratory standard power system simulator PSCAD/EMTDC. Keywords-adaptive neuro-fuzzy controller, asymmetric half bridge inverter, switched reluctance generator, variable-speed wind turbine.

“…The switched reluctance generator is still capable of generating half its normal power for the same coil current. In [8], a Matlab/Simulink system model is developed and used for three-phase switched reluctance generators. Simulation results show that the switched reluctance generators are able to maintain its output with a single phase-short and a single phase-open fault condition.…”

The reliability of aeronautic starter/generator system is very important to the safety of aircraft. This paper investigates a starter/generator system with one dual-channel switched reluctance starter/generator and one dual-channel doubly salient permanent magnet starter/generator. By analyzing the mathematic models of two starter-generators considering magnetically coupling between channels and phases, a Matlab/Simulink model is built. To achieve fault-tolerant operations, a speed closed-loop control strategy and a voltage closed-loop control strategy are proposed for motor mode and generator mode, respectively. The dynamic performance of two starter/generators under normal and open-circuit fault conditions are analyzed and compared. Using the proposed approach, the simulated performances are shown to provide reference for further research.
