Stator winding insulation failure has been one of the major faults in electrical machines due to the degradation of winding insulation materials. The turn-to-turn short circuit fault indicates an early stage of insulation failure. This fault produces distortion of space harmonics in the air gap magnetic field. Capturing these harmonics and reflecting their effect on the measurable quantities from...
In automobiles, Regenerative Braking (RB) / Acceleration Assist (AA) System captures a portion of the Kinetic Energy (KE) dissipated during braking and stores it in a reusable form to assist the subsequent acceleration of the vehicle. This improves the energy efficiency and reduces vehicle emissions. Electric hybrid cars employing regenerative braking systems are popular, but they are expensive and...
The high penetration of Distributed Generators (DGs) increases the need for monitoring and protection of the distribution system. The stochastic nature of the DGs may result in varying fault currents seen by the conventional over-current protection relays and thereby disturb the coordination of the relays. This necessitates an effective numerical relay that can capture the changes in the varying nature...
Due to the increasing interest on renewable sources in recent times, the studies on integration of distributed generation to the power grid have rapidly increased. In order to minimize line losses of power systems, it is crucially important to define the location of local generation to be placed. Proper location of DGs in power systems is important for obtaining their maximum potential benefits. This...
