Abstract: This paper proposes a basic thermal model to estimate the temperature in different points of an induction motor, totally enclosed with external ventilation, for different loads at steady state. This basic model consists simply of a conductive thermal resistance for each point considered in the machine. Thereafter, the intermediates thermal resistan... Show More

Abstract: In this paper the transient stability enhancement of a 30- bus multi-machine system by using Power system stabilizer and increasing inertia has been observed, as single method is not sufficient for this purpose. We have created a three phase fault at time 0.04 seconds at bus 7 and cleared at time 0.5 seconds. On implementing PSS and on increasing t... Show More
