A 300 hp motor and generator testing facility is being completed at Oregon
State University. The testing center is the largest independent testing facility west of
the Mississippi River. This regional resource center will incorporate state-of-the-art
features that set it apart from other testing facilities. An induction machine with a
modem regenerative power electronic converter is being used as the dynamometer.
This regenerative dynamometer system significantly reduces the amount of power
necessary for testing, allows for extremely flexible computer controlled testing, and is
able to test adjustable speed machine systems from 100-4000 r/min. The
dynamometer system is able to fully test both motors and generators of 240 hp from
no-load to 125% rated load. A virtual instrumentation system provides tremendous
flexibility and measures instantaneous, rms, and spectral signal values.
Because the system is designed for testing over a wide speed range, it is
necessary that all dynamometer losses are isolated and tabulated for the entire speed
range. Initial fixed speed testing was performed on a 60 hp induction motor and
standard report formats were generated for this and future test center use. The results
were compared to the manufacturer's original testing data. To demonstrate the ability
to test generators by using the dynamometer as a prime mover, a set of tests were also
performed on a synchronous machine in accordance with IEEE standards. / Graduation date: 1996
