Abstract:This paper presents the design and implementation of small power switched reluctance generator (SRG)-based wind energy conversion system supplying stand-alone DC load. A finite element analysis (FEA) model is developed for the existing machine geometry using MagNet 7.1.1 and solved to obtain parameters like flux linkage, inductance, and torque. The data obtained from the FEA model are utilized to develop an SRG machine model in the MATLAB/Simulink environment. The phase winding of the SRG is excited through asymmetric half bridge converter with dedicated buses for source and load to avoid absorbing a large current from the excitation battery. The performance of the system is analyzed for various values of torque input and dwell angle; the output of the SRG is supplied to the stand-alone DC load. A wind turbine with perfect maximum power point tracking algorithm is modelled to extract maximum power from the wind turbine and it is emulated by a DC motor. We implemented the SRG-based small power wind energy conversion system using a microcontroller. The results are examined.

“…The magnetic independence among phases permits the machine to keep operating when phase-lacking faults occur, if a proper power converter and related control procedure are used. This leads the SRG to have a better fault tolerance ability [2][3][4][5].…”

A Non-Unity Torque Sharing Function for Torque Ripple Minimization of Switched Reluctance Generators in Wind Power Systems

This paper deals with a new torque ripple minimization method for a Switched Reluctance Generator (SRG). Although, the SRG has many advantages including simple and robust construction, and high power density as a generator, it has not been widely employed in the industry. One of the major drawbacks of the SRG is its high torque ripple that results in high noise operation of the generator. In this paper, a non-unity Torque Sharing Function (TSF) is proposed to minimize the torque ripple over a wide speed range of operation. Simulations as well as experimental results are presented to verify the effectiveness of the proposed torque ripple minimization technique.

“…Once the signal reaches the turn off angle, the increase in phase current can no longer be controlled. Therefore, the current chopping mode is not suitable for generating operation especially at low speed and under heavy load conditions [61].…”

This paper provides a comprehensive review of the recent development on the switched reluctance machine operating in generating mode in both the low and high speed operations. The machine consists of a salient rotor and stator poles and controlled via switching of the power electronic devices. There is a steady development of the machine operating in the motoring mode; however, its generating operation is still under study. This paper gives an overview of the machine, followed by the principle of operation in generating mode and briefly discusses the structure and types of control methods which involve the switched reluctance generator (SRG). Due to its geometry simplicity and advantages such as robust, ability to operate over a wide speed range and absence of permanent magnet and windings on the rotor, the SRG promises to be a good candidate for variable speed application.
