Dynamic Characteristic of Permanent Magnet Assisted Self Excited Synchronous Reluctance Generator (original) (raw)

2020

Abstract

The use of self-excited synchronous reluctance generator is gaining interest due to its simplicity and inexpensiveness in terms of manufacturing. The problem of this machine which is best suited in a standalone application is that it has poor power factor. This paper presents a comparative study of a PM assisted synchronous reluctance generator with a regular reluctant generator. The machine was studied using rotor rotating frame and embedded MATLAB was used to simulate the machine. Results shows that the generator with PM exhibited a better performance in terms of voltage and power output due to the PM flux. This was possible at power factor of 0.999 and excitation capacitor value of 70uF and PM flux of 0.8. Reducing the value of the excitation capacitor hampered the generator performance. However, increasing the PM flux at the lower capacitor, produces a suitable voltage for the generator. Keywords: PM Flux, Excitation capacitor, Output power, Voltage build up, Torque. Cite this A...
