PROJECT TITLE :

Analysis of a Nonintrusive Efficiency Estimation Technique for Induction Machines Compared to the IEEE 112B and IEC 34-2-1 Standards

ABSTRACT:

International potency testing standards, such as the IEEE 112-B and IEC thirty four-2-one, will verify the potency of an induction machine (IM) accurately at the value of hindering the machine's productivity. Alternatively, various methods used to determine a machine's potency in situ do therefore at the cost of accuracy. This paper proposes a technique that determines an IM's potency over a range of load conditions from tests conducted and targeted around one thermally stable load purpose in the smallest amount intrusive manner possible. The results are then compared to those of the IEEE 112-B and IEC 34-2-1 motor testing standards using segregated loss analysis. It was found that despite the proposed algorithm being unable to accurately determine core losses, the potency of a machine can be estimated to within zero.five%–two.1% and 1.one%–one.seven% error, compared to the IEEE 112-B and IEC 34-a pair of-one standards, respectively over a 25%–a hundred and fifty% machine load profile (dependent upon the proposed technique's implementations).
