Transient Characteristics of Cylindrical Stator 6/2 Switched Reluctance Generator

Abstract

The switched reluctance motor can be used in generation mode by selecting the firing angles of the phases. Switched reluctance generators have been identified as a potential option for military aircraft, variable speed wind turbine and automotive electric power systems. Switched reluctance generator (SRG) has various desirable features which include simple and solid structure, easiness of maintenance, small moment of rotor inertia and low cost. This paper presents detailed transient characteristics of a 6/2 cylindrical stator switched reluctance generator (SRG) through experimental observation. The results are computed from the transient analysis equations. The computed results are presented to validate the effectiveness. Due to highly nonlinear characteristics of (SRG), iterative simulation of the generator model on the range of parameters and control variables has been used. Maximization of (SRG) output power has been addressed in this paper. Phase self-inductance, phase voltage switching angles, DC excitation voltage level and shaft speed of the generator have been identified as control variables affecting output power. Depending on the application each one can be defined as control variable.
