Virtual instrument based fault detection in three phase circuit

Abstract

At present the field of science, engineers and technology is so dynamic due to recent improvement in computer and other technologies. The advances in computer field developed such programs to solve our traditional and novel problems of practical life. We can solve our complex problems within a few minutes due to high computational abilities, accuracy of computer based programs. For electrical people there are many software programs are currently used in academia to design and analyse different kinds of electrical circuits and models. The main objectives of this report is to design three phase power system models using the VI modules available , and detect the types of of fault like 3-phase (L-L-L), 3-phase to ground (L-L-L-G), Line to Ground(L-G), Line to line(L-L), Line to Line to Ground(L-LG) in power system . Initially the simulation work is done by using a software based programs named Multisim, which is an electronic Schematic Capture and simulation program .After completion of the simulation task the real time three phase hardware circuit interfaces with the LabVIEW model to detect the real time faults in power system.
