Conversion of a switched reluctance motor to operate as a generator for wind power applications

Abstract

climate change effect become number one concern in many countries due to the effect that will have on human life. Renewable energy found to be one of the most effective ways to overcome this problem, wind energy is part of the renewable and one of the most growing areas in this field. In this paper the definition of switched reluctance generator and the principal of operation will be discussed, the excitation cycle and its relation to the switching parameters, methods on the switching phenomena will be discussed, low speed circuit and high speed circuit will be explained, output power of the SRM

Switched Reluctance Generator - Modeling, Design, Simulation, Analysis and Control a Comprehensive Review

“…To overcome this problem some researchers used a slot of permanent magnet on the edge of the stator pole to create a magnetic field that run through the rotor to both sides of the stator; the rotation of the rotor will change the permanent magnetic flux which induces alternating voltage in the stator winding. The others have chosen an external power source to help in self excitation for this SRG like using a battery or capacitor to create a magnetic field around the stator winding for a set time and then this magnetic field will be used to create electricity when the rotor moves [1]. The concept of attaching rectangular pieces to each pole of the machine phase for self excitation has been presented and implemented the same in three different means in [13].…”

“…This led to the increased interest in researchers of electrical community as this machine is an attractive solution for worldwide increasing demand of electrical energy. The shortcomings of the conventionally used generators have turned research attention to a more simple and robust variable speed switched reluctance generator (SRG) which exhibits the most desirable features of a generator [1][2][3][4][5][6][7][8][9][10][11][12]. The published literature on switched reluctance generators has dealt with the technical issues related to the machine technology such as generator modeling, design, simulation, analysis and control.…”

“…Due to the absence of winding in rotor of SRM, it can withstand high temperature and can rotate at very high speeds. The number of rotor poles, number of stator pole and number of phases decides the type of SRM as shown in the Figure 1 [4].…”
