Virtual measurement system for AC machine using labview

Abstract

It is widely accepted that contemporary scientific experimentation on electrical machines requires extensive measurements and acquisition of various data. In this project the development of virtual measurements system based on labview software environment is described. This system is able to perform an essentially large number of simultaneous electrical and mechanical physical variables measurements of an AC induction machine. In the studied case only voltages, currents (of the three phase system ),speed and torque are measured and recorded in real time , while power, reactive power, apparent power,total harmonic distortion…etc are calculated according to the IEEE(Institute of Electrical and Electronic Engineering) std 1945-2000. A graphical user interface is created to allow an accurate measurements display and data recording using TDMS function (Writes data to binary measurement files (.tdm or .tdms)).
