ABSTRACT
This paper presents the development of an experimental bench for performing time-domain tests on synchronousmachines at standstill. The test bench allows the collection of experimental data which can then be used in theparameter estimation of mathematical models of synchronous motors and generators. The system development isbased on the LabVIEW programming language. It effortlessly allows the calibration of voltage and current sensors, thed-q magnetic axis positioning of the synchronous generator, and the spectral analysis from the collected data. Inaddition, the testing environment includes non-sophisticated instrumentation elements and a power amplifier. Thisexperimental bench has a friendly user interface which guides the user throughout a defined methodology to allow theachievement of the different time domain tests on synchronous machines. A 7kVA, 220V, 60Hz synchronousgenerator was used to show the functionality and usefulness of the test bench in research and teaching electricalmachine theory.
