    Abstract: Every year Bangladesh experiences high density of lightning as it is a tropical country. In recent years, lightning related deaths and injuries have increased in Bangladesh. In 2016 due to lightning, 81 people have died in just two days. Therefore, the GoB has acknowledged lightning as natural disaster. The survey portrayed that around 70% populati... Show More

    Abstract: This paper presents an approach to minimize the electromagnetic torque ripple of a synchronous reluctance generator (SynRG) with a magnetic field created by externally excited rotor coils. The synchronous reluctance machine is widely used in low and medium power systems such as wind power generation and new electric vehicle technologies. This paper... Show More

    Abstract: Static eccentricity will cause the abnormal distribution of air gap magnetic field and further affect the electromechanical characteristics of the generator. This paper comparatively studies on the end winding electromagnetic force of turbo generator under different eccentricity ratio and eccentricity angle. The analytical expression of end winding...

    Abstract: This paper proposes a doubly-fed induction generator (DFIG) model built on three simulation platforms: Maxwell, Simplorer and Simulink. It can solve the overall modeling problem of the DFIG system effectively. In this paper, the generator physical simulation model (rotating shaft, rotor, stator and winding) are first established in Maxwell. Then, t... Show More
