Development and efficiency estimation of a regenerative test rig for induction motor testing

摘要

This paper presents the development and error analysis of a flexible test rig which is intended for emulating the static and dynamic characteristics of some mechanical loads found in industry. The test rig will provide a laboratory-based platform for assessing the efficiency of inverter-fed induction motors (IM) within a wide range as well that of variable speed drives (VSDs). The use of an Active Front End (AFE) with regenerative capabilities allows the power generated by the motor drive to be recycled within the system. An in-depth error analysis is conducted on the complete system. This is done by analyzing raw data obtained by means of 2 commercial instruments. Detailed comparisons of the error bands were done for the results obtained.
