Distance relays used for protection of transmission lines have problems of under-reach, over-reach and maloperation due to high impedance faults. Further the problem is compounded when the distance relays are used for protection of double circuit transmission lines due to effect of zero sequence mutual coupling. Different types of faults on a protected transmission line should be located correctly...
Field oriented control (FOC), also known as vector control of induction motor drives is very useful technique to obtain high performance speed response. Implementation of field oriented control requires the knowledge of instantaneous magnitude and position of rotor flux and load behavior for the correct dimensioning of an induction motor. This paper demonstrates estimation of feedback signals in a...
